Freakonomics Radio - 535. Why Is Flying Safer Than Driving?

Episode Date: March 2, 2023

Thanks to decades of work by airlines and regulators, plane crashes are nearly a thing of the past. Can we do the same for cars? (Part 2 of “Freakonomics Radio Takes to the Skies.”) ...

Starting point is 00:00:00 Tell me about a frightening incident you've had as a pilot. Okay, I'm going to apologize to my mom and my wife on this one. Uh-oh. I had a smoke and fumes emergency when I was departing Guam, and we thought our airplane was on fire. And when you have an internal fire, you have not a lot of time. So we turned around. We had to put the airplane on the ground very quickly. We had a lot of gas on board. I was in charge that day, even though the other pilot was even more senior in experience than I was. But I said, okay, I'm going to do these tasks,
Starting point is 00:00:37 you're going to do these tasks. And we had separated mentally to go take care of what we needed to take care of to get that airplane back on the ground as fast as we could. And when we reconvened, all things were done. We had our oxygen masks on, we landed the airplane safely and egressed the aircraft. How scared were you? At the time, you're not scared. Your training kicks in. You just start turning in an automaton and doing what you know to do correctly. That is Adam Yuhan. Today, he's a pilot for a major U.S. airline, but the emergency he described was some years ago during an Air Force flight. It was a Boeing KC-135 Stratotanker heading out to refuel a bomber midair over the Pacific Ocean. That's why his plane had so much gas on board.
Starting point is 00:01:30 Yuhan joined the Air Force in 2001, and he's still in the National Guard, training other pilots. The first time I said that I was going to be a pilot in the United States Air Force was when I was in first grade. We were walking home from school, and the three other little guys with me said, yeah, no, you can't do that. That's only for, like, superheroes. I asked Yuhan if he'd ever had a frightening incident as an airline pilot. So in the airlines, I've never had a real issue that I would call frightening. The safety records are true. Go ahead and read the NTSB reports. You're gonna be blown away at how few incidents there truly are. This is correct. According to the NTSB, or National Transportation Safety Board,
Starting point is 00:02:05 which investigates every civil aviation accident in the U.S., since 2010, there have been only two fatal accidents involving large U.S. carriers. Two. That's out of more than 100 million flights. It's a miracle. It's a miracle that we can push enough thrust out of the back of this airplane to make enough air go over the wings to then make that airplane rise into the air and fly smoothly, safely to a destination and then lower it by controlling control surfaces and making them move in certain ways that we can bring the airplane down at an exact speed to touchdown and then take you to your gate.
Starting point is 00:02:48 Today on Freakonomics Radio, it wasn't always this way. If you go back 30 or 40 years, air crashes were not uncommon. And now? It's safer than riding a bike, safer than driving a car, safer than crossing a street. And what can the rest of us, the people driving cars especially, what can we learn from the people who fly planes? In commercial aviation, we train ad nauseum. There are, of course, other things that can go wrong.
Starting point is 00:03:15 They just made an announcement asking for a medical professional. And we do a little safety training of our own. Release seatbelts. Leave everything. Release seatbelts. Can I just say, I'm flipping out right now, even though I know I'm going to sit in the chair. This is Freakonomics Radio, the podcast that explores the hidden side of everything, with your host, Stephen Dubner. This is the second episode in our series, Freakonomics Radio Takes to the Skies. Early on, we deputized our listeners to make audio diaries of their recent airline trips. So here's a listener named Alex Polson traveling
Starting point is 00:04:11 with his infant son. Okay, so we got him all wrapped up in a blanket, rocking him now, pacifier in. Hopefully we can get him to sleep. We heard from Faye Walsh-Drewyard, whose concern was other people's kids. There are three children sitting behind me under the age of 10 with no parent nearby, at least that I can tell. And I have been kicked a few times. And we heard from a listener named Charlie Wood, who was just enjoying the ride. Flight attendant said it's going to be a bumpy arrival, but the way I look at it, turbulence is kind of like a free roller coaster.
Starting point is 00:04:59 We received hours and hours of audio diaries covering every phase of the air travel experience. People were concerned about all sorts of things, tight connections and tight seats, lost baggage, noisy passengers, smelly food. But there was one concern that not a single person mentioned, getting in a crash. And that makes sense. Last year, there was only one fatal crash in the world that involved a large commercial jetliner, a China Eastern flight that killed all 132 people on board. And that crash is thought to have been caused by a suicidal pilot. Some other crashes involving smaller aircraft brought the global total of people killed aboard commercial carriers to 174. That's for the entire year. That same number of people die in car crashes every day and a half in the U.S. alone. Last year, there were zero deaths in the U.S. on regularly scheduled
Starting point is 00:05:55 commercial flights. Private air travel is riskier. There, around 300 people die each year in the U.S. Still, the overall progress in air safety is almost hard to fathom. So how did that happen? Yes, you know, I'll knock on wood here, but it's really, you know, pardon the pun, it hasn't been by accident. That is Billy Nolan. And I am the acting administrator for the Federal Aviation Administration. The FAA regulates just about every aspect of civilian aviation,
Starting point is 00:06:26 airports and airlines, air traffic control, and the certification of pilots and aircraft. If you look back to the early 90s, while the rate was fairly low, we could still see more accidents than we wanted. So we set about to create a framework which was designed to bring together the regulator and the airlines to openly share safety data and trending information. So we set out to reduce what we call the rate of fatal accidents by 80% over 10 years. We wind up exceeding that, reducing it by 83% from 1997 to 2007. And in 2007, we realized we wanted to expand that even more.
Starting point is 00:07:09 We wanted to continue to reduce that fatality risk by 50%. In the 1970s, there was one death for every 350,000 passengers who took a commercial flight anywhere in the world. By the 1990s, that number was one death for every 1.3 million passengers. And today, it's roughly one in 8 million. It is a great and an enviable safety record, but we will never claim victory, right? It's one that we're forever innovating, we're forever iterating to say what's next. For all the investment in safety training, which we'll get into later, Nolan says that technology has helped a lot.
Starting point is 00:07:47 You look at the amount of data coming off a modern jetliner. Let's take a Boeing 787. That's got nearly a half a terabyte of data coming off of it per flight. Are there trends that we're seeing that we can have very early indication of something that we need to address? When you think about sensors, things like engine health monitoring, all those can be early warning or early indicators that you might need to do some sort of maintenance. Our goal is to be able to share data openly
Starting point is 00:08:17 and to be able to voluntarily report where we think there are issues out there so that we can address those in an almost real-time manner. Our industry is such that with our regulator, when we see something that looks odd, we want them to know. That is Ed Bastian, the CEO of Delta Airlines, one of the biggest airlines in the world. And when a Delta pilot, for instance, does see something a bit odd… They report it, whether it was due to their judgment or their decision or not. It's a program that our employees all know, as long as they report something they see as an anomaly, they are held harmless as to whether they made a mistake or
Starting point is 00:08:57 there was a judgment error. They may wind up having to go learn from what they did and maybe take a class or receive some additional training. But we want everyone to report anything that they see. Bastian says this sort of program has been a key driver of airline safety. If you go back 30 or 40 years, air crashes were not uncommon. It was something the industry spent an enormous amount of time collaborating together, sharing information, sharing learnings, working closely with the FAA to understand best practices and how we could have an open book with our regulator. This close relationship between regulators and industry plainly has benefits, but it can be
Starting point is 00:09:37 complicated. Two of the worst crashes in recent years, one in Indonesia, the other in Ethiopia, involved a brand new airplane, the 737 MAX, made by Boeing, the other in Ethiopia, involved a brand new airplane, the 737 MAX, made by Boeing, the big U.S. airplane manufacturer. The FAA had certified the MAX as safe, but in both those crashes, the plane's new automation system was found to be at fault. It has been suggested that the FAA's cozy relationship with Boeing led it to sign off on the automation system before it had been fully tested. Those two crashes killed 346 people. That said, airline travel has become the safest form of transportation in the world. It's safer than riding a bike, safer than driving a car, safer than crossing the street. So, Ed, in a given year in the U.S., roughly 40,000 people die from traffic crashes. If you
Starting point is 00:10:30 look at the global numbers, it's more than a million people a year. And yet, to most people, an airplane seems a lot more dangerous than an automobile. Can you talk about that from the perspective of an airline CEO? Well, safety is paramount, and we're proud of that. You compare that to the auto industry, obviously, you have a lot more operators, so you've got a lot more variability. And the other thing that's very different, you will not see airlines compete on safety. We will not say that we're the safest airline in the sky. All of our airlines in this country are safe. However, autos, for many many years used to compete on safety.
Starting point is 00:11:05 It used to say on the most reliable car in terms of safety and other ratings. They don't do it as much anymore. And that's one of the things I've learned from the airline industry. Safety is not something we should compete on. We should collaborate on. Do you think that the average airline pilot is a safer automobile driver than the average automobile driver? Oh, that's hard to know. I do know that our pilots also receive a tremendous amount of support in terms of technology from the aircraft itself. I'm sure they're safer flying planes than they are driving cars. We tried to find some data on whether airline pilots, when they're driving cars, are safer or less safe than the average driver, but we couldn't.
Starting point is 00:11:50 We asked Billy Nolan, acting FAA boss and himself a former military and commercial pilot, if he had seen any such data. I don't know of any, but if I could say one thing, One of the things we look for in pilots is that sense of perception. Now, I'm not going to suggest that every pilot has perfect situational awareness, but I can certainly assert that every commercial aviation pilot has an enhanced sense of awareness because you're constantly thinking about what are the threats that could impact my flight from the time I depart to the time I land, whether birds, thunderstorms, traffic, terrain, all of those things that we are forever training to and we're thinking about. Do you find that that sense of observation and awareness are more natural or
Starting point is 00:12:38 learned? You know, there's a lot of assessments that pilots go through. Part of it is spatially, physically, you go through all kinds of testing. And over the arc of your career, you're presented scenarios to say, how would you react? You're flying over the Rocky Mountains. And what if you were to suddenly have a fire? Or were you starting to have a rapid depressurization? Where would you go? What would you do? In my helicopter days, I was always looking for someplace to land because if something happened, your decisions were almost immediate,
Starting point is 00:13:07 and you had to react. But much of that is learned. We sit down and we talk about the man-machine interface, how we work together, because a lot happens. On a flight deck, you see symptoms. You've got instruments. You say something is happening. But you've got a whole cabin behind you, so you're receiving the stimuli all the time.
Starting point is 00:13:23 And it's your ability to synthesize that and say, is there a threat? Is there something I need to address? We do want you to have that heightened sense so that muscle and that mental memory kicks in. Describe for me you as a pilot, whether it was military or commercial later, the hairiest or scariest moment or flight? I was a helicopter pilot back in the day, and I was flying into and out of Panmunjom. So you're right there on the line between South Korea, North Korea. I found that always to be interesting. That could be another story for another day. Only military would say, I found that to be interesting. But in commercial aviation, we train ad nauseum. So we
Starting point is 00:14:06 try to say, okay, what could happen? What are the possibilities? What are the consequences? What is the greatest outcome? So be it a fire, be it wind shear, microbursts, we put people in the simulator and I used to be a training captain myself to the point we throw the book at them so that that muscle memory and that mental memory is there in terms of what to do. Obviously, you saw it expressed in the miracle on the Hudson, that ability to instinctually know what it is I need to do in the moment, right? That all comes from training. The miracle on the Hudson that Nolan mentioned happened in 2009 on a U.S. Airways flight out of LaGuardia Airport in New York. The plane, an Airbus A320 carrying 150 passengers,
Starting point is 00:14:47 had just taken off when it hit a flock of birds and lost power in both engines. The pilots, Captain Chesley Sully Sullenberger and First Officer Jeffrey Skiles, were able to glide the plane into position and land it safely in the Hudson River. Everyone survived. One NTSB member called it the most successful ditching in aviation history. Much was made of the fact that Sullenberger was a longtime Air Force pilot before moving into commercial. You don't lift one weight one time and you're the size of Arnold Schwarzenegger. It took him rep after rep after rep to do what he did.
Starting point is 00:15:28 It takes a lot of reps to get good at these things. Well, the same thing is when you're flying an airplane. That, again, is Adam Yuhan, another commercial pilot who used to fly military. Those simulators, we are thrown a lot of different problems, and we have to work together to get the problem done. There just hasn't been that much airline catastrophe in the past 15, 20 years. And it's just been gradually getting safer and safer to the point where, gosh, I mean, I think it's bizarrely safe. What would you say have been the key drivers of that improvement? If you go back to the 20s and the 30s, Pilot was a sky god. They could figure
Starting point is 00:16:02 anything out, right? Well, slowly but surely, they had to adjust to technological inputs like the first autopilots that came online or the ability to use navigation, like instrument navigation, not just looking out at a cornfield and going, oh, yeah, I think that's the right way. Why things just got safer is the evolution of this culture of saying, hey, technology can help us. I asked you, Han, if being a pilot has made him a better car driver. My arrogant self would say yes. For me personally, I'm able to tap into that situational awareness and task prioritization mindset that's been beaten into me over 20 years of being a pilot. Like, I really, I've adopted that mentality. So what would it take to bring some of the safety standards of airline travel to roadway travel?
Starting point is 00:17:00 I went back to Billy Nolan for this. His FAA, by the way, is part of the Department of Transportation. In fact, it makes up around 80% of the Department of Transportation. The airline industry has become remarkably safe, to the point where I would posit that the average person, when they get on a flight, they don't even really think about safety anymore. They think about, my seat's too small, the food is not good, and so on. So you could say that complaining is sort of a luxury of not having to worry so much about safety. If we look at automobile travel, however, we've made great strides over the decades, but not as great as one might like. And indeed, there's been a setback during the pandemic. And there are wrinkles like pedestrians now are dying at a higher rate in the last few years than in the
Starting point is 00:17:41 past. I realize there are many, many, many fewer miles flown than there are miles driven. Everybody's a driver. Most of us are not pilots. But are there lessons to be drawn from aviation that can make driving safer? Absolutely. We know just exactly to your point.
Starting point is 00:17:57 We say aviation is the safest mode. It comes as a result of our willingness collectively to say that we cannot tolerate a fatal aircraft accident. When we look at the ecosystem of all things automotive, there's so much more in play, right? You've got fewer players in the aviation arena, and you've got high levels of controls around certification of pilots, certification of mechanics, certification of air traffic controllers, heavy oversight of airlines. I can tell you, I've had communications in the past with automobile manufacturers and their
Starting point is 00:18:30 senior leadership in the safety space of how do we work together. So I think you'll see us continually advance at the federal, state, and local level. We're all vested in that zero fatal traffic accidents, right? And when we can come together and leverage technology, we can certainly put a big hole in that big number, which is unacceptable. I liked your answer. It was a diplomatic answer, but let me poke at a couple pieces of it because pilots, let's say, both training, certification, recertification, but also things like sobriety tests, right? And monitoring with technology and so on. Doesn't it seem a little bit bonkers that just about anybody can get behind the wheel of a car just about any time and put the public at risk? will say, you know, if you've taken a defensive driver course, here's a reduction to your premium, right? So there are some voluntary tools out there. I will say personally, I'm a big advocate
Starting point is 00:19:29 of recurrent training. My training used to be every nine months during my airline career. And I knew that I was going to get put through my paces to make sure when I came out of there, there was a sense of comfort on the part of the check captain that Billy's ready, right? And so could we take some of that and see how that would work on the automotive side? I think that's an opportunity for us to have that kind of conversation. It was never a given that we were going to get to zero fatalities in aviation, right? It took a lot of work, as I said. Look at the work being done. I mean, I've got several, you know, cars and one for my, one of my daughters, you know, it's got pre-collision
Starting point is 00:20:04 warning, it's got lane departure warning, lane keep assistance. So we're seeing technology evolve. We've got a collective sense of ownership in aviation, which is why we are so safe. We need that same collective sense of ownership and responsibility that when I get behind the wheel of something that weighs 3,000 plus pounds, right, the physics of it is something that people just don't always account for. Commercial airliners rarely crash these days, but smaller and private planes still crash with some regularity. I'm curious what the FAA is doing to diminish that. Yeah, it's a great point. We have done a lot of work in the general aviation space. We have something called the General Aviation Joint Steering Committee. We have the helicopter safety team. I was at Oshkosh this summer. 10,000 general aviation airplanes were on the ground. 600 plus thousand people were in attendance. And we talk about safety. And I got to tell you, it's a pretty responsible community. We are seeing technology that used to be the purview of airliners.
Starting point is 00:21:06 Now, some of that can move quite fast into general aviation. You've got better tools. You're using iPads. You've got better systems that have weather, that have moving map displays. In fact, sometimes they can move even faster because we're such a heavily regulated industry when it comes to commercial passengers. But we're making every effort. Coming up after the break,
Starting point is 00:21:25 commercial jets almost never crash, but there is still a risk to flying. Turbulence is the biggest threat to our safety. I'm Stephen Dubner. This is Freakonomics Radio. We'll be right back. Flight attendants, prepare for arrival. I don't like our angle here.
Starting point is 00:21:46 Am I paranoid? No, you're right. So I don't like the tension. Can you tell me, like, what's causing this emergency evacuation? Well, you might see it in a second. I'm going to let it go and see what you think. You're cruel. I know.
Starting point is 00:21:59 I'm sorry. That is Katie Truitt. She used to be a musical theater performer, and now she trains flight attendants at the Atlanta headquarters of Delta Airlines. The training is six weeks long, and much of it involves responding to emergencies. Right now, we are inside an old plane that's been rigged up with hydraulics to simulate turbulence. Great. There it is. So this is a command from the captain that tells us what to do. Go, stay down. Bend over.
Starting point is 00:22:29 Stay down. Bend over. Stay down. We're checking outside. We're looking to see if it's safe. We're looking to see what our conditions are. Evacuate. Evacuate.
Starting point is 00:22:40 All right. So then we tell you to get up and get out, which is release seatbelts. Leave everything. Release seatbelts. Can I just say, I'm flipping out right now. Release seatbelts, leave everything. Come this way, leave everything, jump and slide. And you're going to put your hands out right in front of you, put them right out in front of you, and arms out in front. I'm jumping from here, I stand there.
Starting point is 00:23:00 You jump from here, arms straight ahead. There you go. Nice. Nicely done. Even though every passenger on every airplane sits through a safety briefing at the start of every flight, Truett acknowledges that very few people think they'll need that information. Everybody thinks that our job is really to give you peanuts, right? But actually, our job is to keep you safe. That's the number one job. We are actually first responders in a way.
Starting point is 00:23:27 Everything from de-escalating someone who's angry about something to evacuating an aircraft. And we are trained to evacuate an aircraft in 90 seconds. And 90 seconds for 300 people is a lot. What's going on over here? She's actually doing a CQ. This is our continuing qualification.
Starting point is 00:23:43 So continuing qualification means our flight attendants all have to come back every 18 months to get re-qualified to be a flight attendant. Hey, Katie. Yeah. We actually need this real fast. Oh, sure. Oh, I'm so sorry. Pardon me. You mean actual training?
Starting point is 00:23:56 On actual training. Isn't this more important, getting a demonstration? Worldwide, there are only around 30 full plane evacuations each year out of around 40 million flights. Yet another sign of how safe airline travel has become. If you need help from a flight attendant, it's more likely because you're having a heart attack or other medical issue. And that happens around 44,000 times a year. We're trained to understand how to handle basic medical issue. And that happens around 44,000 times a year. We're trained to understand how to handle basic medical problems. How many times in your flying career have you needed to ask for a doctor or nurse on board?
Starting point is 00:24:35 Three or four. And how many times did you get one? Every time. They just made an announcement asking for a medical professional, and there's flight attendants running around. It's not quite clear what's going on. That is Connor McGill, one of the Freakonomics Radio listeners who sent us an audio diary of a recent trip. He was flying from Amsterdam to Minneapolis.
Starting point is 00:25:00 When the call for help went out, his plane was already over the Hudson Bay in Canada, and there wasn't a good option for a closer airport than Minneapolis. The patient was apparently unconscious, but luckily there was a passenger on board with medical training. So we're definitely beelining it to the airport. You can tell that the flight path is different than normal. It is very important that everyone remain in their seats. Once again, everyone needs to remain in their seats upon our landing
Starting point is 00:25:30 and so the medical personnel can come aboard the aircraft. There's airport fire EMTs. Okay, looks like they got them off. That looks scary. That's unfortunate. When somebody goes unconscious on a plane, that's a serious issue. That is Sarah Nelson. She is a flight attendant with United Airlines, as well as president of the Association of Flight Attendants. We're trained to jump into action,
Starting point is 00:26:06 give CPR, revive people. Flight attendants do this every single day. This is a big part of what they do. And when there's that medical emergency, we also have to be on the lookout for any security risk because we have been trained that anything that happens on the plane could be a distraction from a bigger plot. The role of the flight attendant has evolved along with commercial air travel. So our career was started by a brave woman, Ellen Church, who was a certified pilot and certified nurse, by the way. And she really, really wanted to fly. And so she tried to get a job as a pilot. And the airlines just said, no, you know, women don't belong in the flight deck. They're too emotional. And so she made the argument that passengers get sick and there should be someone in the cabin to be able to assist with
Starting point is 00:26:49 that. And if they fall ill, they need someone to attend to that. You don't want to land with dead passengers. So she made the argument that flight attendants or stewardesses back then should be in the cabin to attend to the needs of what was mostly men flying for business in those days. She was really arguing that flight attendants needed to be in the cabin in order to take care of the emotional men's needs. So, ha, ha, ha. You know, from the very beginning, there's sexist tones there. We were defining this job as women's work, and we had to fight through all those discriminatory barriers that were put up for our job. We had to quit at age 30. We had to step on a weight scale until 1993. You couldn't be married or have children. And we fought for diversity, too. We fought for men to have the same rights on the job, and we fought
Starting point is 00:27:41 for the airlines to be inclusive and hire people of color. As for the current functions of the flight attendant, Nilsen says there is one constant danger to be aware of. Turbulence is the biggest threat to safety. So a lot of people are used to choppy air, where the airplane is making your coffee spill, things like that. We're encountering some pretty decent turbulence right now. Nothing that would make the news. However, all the flight attendants have been ordered back into their jump seats
Starting point is 00:28:12 and everybody is required to have their seatbelt on. That is Freakonomics Radio listener Brandon Murrell on a flight from Tokyo to Chicago. I've never once been scared by turbulence. If you know anything about the engineering behind the planes and the wings, there's no reason to be scared at all. Honestly, the most stressful part of turbulence is making sure this glass doesn't topple over. That's about the only thing I'm worried about. It is true that turbulence doesn't mean the plane is about to crash, but it can still be dangerous. Sarah Nelson again.
Starting point is 00:28:45 Severe turbulence is when there's like an air pocket that's hit where the plane is dropping very quickly. There's no warning for it. The plane will just drop thousands of feet. And that's why you'll hear people being thrown to the ceiling, hitting their head and coming down, along with anything that's loose. So we take turbulence extremely seriously. The flight deck will often be working with ATC to get reports of turbulence ahead. It's something that all the pilots will report out. Over the Pacific Ocean, they don't have the same kind of technology to be able to identify where that turbulence is. So that is actually also more likely where you're going to hit severe turbulence. They hit a bubble in the air and
Starting point is 00:29:33 the bubble burst and we collapsed for a little bit. That is Pepper DeRoy. He's a singer and bassist for an Australian country rock band called Hurricane Fall. In July of 2019, the band got on board an Air Canada flight. It was AC-33 from Vancouver to Sydney with an unscheduled stop in Hawaii. Hurricane Fall had just finished playing some dates in Canada. We all had a pretty severe hangover. And that's Luke Wieldon, a guitarist in the band. It was our last night in Canada and it was successful. So everyone was ready for a good sleep, really. Flight was fine until, yeah, we were just past Hawaii, I believe, and I was awake. But, yeah, there was a sudden jolt and half the plane flew into the roof. It was just shocking.
Starting point is 00:30:33 Wilden had his seatbelt on, but DeRoy didn't. I got up, went to the toilet, came back, was walking down the aisle, sat down with no seatbelt on. The plane shook a little little and in an instant, I just remember being back on the seat with what I thought was just a sore arm and then proved to be much more. The flight attendants were awesome. They immediately started trying to help people
Starting point is 00:30:57 and stop people that were bleeding and that sort of stuff. The most disturbing thing was that there was nothing from the pilot for like 10 minutes. I was like, you've got to say something, man. It felt like forever. I don't know how long it was, really, but it was a long time. And I don't know, he was probably busy saving our lives. So, you know, there's that too.
Starting point is 00:31:23 The plane made an emergency landing in Hawaii. 37 people were injured. The doctors in Hawaii cleared DeRoy and his bandmates to fly back to Australia. When he got home, he went to the hospital. I was like, yeah, it doesn't feel right. And then when the doctor showed me the CT scan with fragments of my neck floating around, he's like, just stop what you're doing right now. Put me straight in a neck brace and like, do not move. DeRoy had a broken neck. Took him 18 months to recover. Turbulence is the leading cause of accidents on larger U.S. commercial flights, and its share is increasing. That's because other types of flying accidents
Starting point is 00:32:03 have become less common. But there may be another reason. Sarah Nelson again. The underlying issue here is that turbulence is getting worse because of climate change. The idea here is that rising temperatures are making air currents more unstable. And that is essentially the definition of turbulence. Here's Adam Yuhan. We could go into more specific meteorological terms, but the reality is you're going through an air that is no longer as stable as the air that you just came out of. And that is why even in the middle of a seemingly smooth flight, a pilot will sometimes turn on the seatbelt sign. It's the biggest risk mitigation strategy
Starting point is 00:32:43 that we have in the airplane. We don't want people to get hurt. Nobody wants anybody to get hurt on an airplane. That seatbelt is really there to protect you because if you hit turbulence hard enough, it can lift you out of that seat and move you around to that airplane any way it wants to. The good news is that predicting and avoiding turbulence is getting easier. 30 years ago, there was no way except for a forecast that was printed out. And back in the day, Northwest Airlines had these turbulence plots, which were the envy of the industry.
Starting point is 00:33:13 Now, a lot of other airlines have adopted this methodology. My airline has probably one of the best weather radar packages on our tablets. We have a different Wi-Fi on board the airplane. And when it's working, which most of the times is, we can actually see down the road where there could be turbulence issues. And then we can do stuff like climb up, descend, go left, go right, navigate around it. I wish if I was in person, I'd show you, you'd be blown away by this system. By what you can actually see. Oh my God. I mean, you can see all the earthquakes
Starting point is 00:33:45 that are happening in the world, volcanic activity. It's wild. And you spin the globe around and you can see everything. It's so cool. You know what? I just got a great idea to go to the bosses with.
Starting point is 00:33:55 I'm going to say we should be doing little mini documentaries and say, hey, this is how we do all these different things. I mean, they wouldn't be a hit with everybody, but a lot of people would love two minute informational clips about how things work. And how does all that information get onto the pilot's tablet?
Starting point is 00:34:13 We're set up with almost two different groups. That is Warren Weston. He is a lead meteorologist at Delta Airlines headquarters in Atlanta. We've got a division where we look at upper air features, turbulence, thunderstorms, keeping an eye on volcanoes, ozone, all the different kinds of things that could interrupt a flight that's at cruise altitude. The other side is more on the surface side, where we're looking at weather on the ground, weather at our big airport operations, New York, Atlanta, Los Angeles, and we're doing hour-by-hour forecasts for those hubs.
Starting point is 00:34:52 Just describe this screen, which is a beautiful screen, but people can't see it. What we're looking at here is tonight's routes that go across the North Atlantic Ocean to Europe. So that's these tracks. The tracks are kind of like a highway in the sky. We're producing turbulence forecasts, and maybe it will show, hey, we're expecting some turbulence along this route between 30,000 and 35,000.
Starting point is 00:35:16 So when we take that information to the flight planner, they might file their flight that night higher, maybe 38,000, 40,000, so that they are able to go over or around the depicted areas. There are a lot of meteorologists in the world, and there's a lot of information you can buy. Why does Delta bother to have this pretty big... How many meteorologists do you have? So we've got 25 meteorologists.
Starting point is 00:35:41 So why is that an in-house function, meteorology? We are looking at things a lot more tailored towards our operation. A lot of the stuff that we produce, those are products that they aren't getting anywhere else. And what's the ROI on that for the airline? Is it worth having 25 of you? Yeah, I think it is because we, first of all, we're a global airline, so we're covering our routes across the Atlantic Ocean, the Pacific Ocean, Hawaii routes, all the domestic routes, South and Central America. What about you? Why did you become a meteorologist? I grew up out in Colorado and I would get frustrated when it wouldn't snow. I wanted to go skiing and so when I would see a forecast, they would call for snow and maybe
Starting point is 00:36:26 we would only get a little bit. The young me was very interested in why is this happening? Why can't they get this right? Weston's meteorology department is one of many departments spread across a vast expanse in a building adjacent to the Atlanta airport. This is Delta's OCC or operations and customer center. The person in charge is a man named Greg Brandner. We meet up with him in a conference room that feels as serious as its name. This is our IBR, so incident briefing room. It is built primarily as a command center for an incident. If we have an incident or accident, incidents and accidents do happen. We have cyber threats now that happen. We would stand this room up and it's built for
Starting point is 00:37:11 senior leaders to come in and be able to work through the incident, be briefed, and then work it through till the end. Brander walks us out onto what looks like a Wall Street trading floor. You could call it a trading floor because there are thousands and thousands of transactions that are taking place. What do you mean? What kind of transactions? Whether it be a dispatch release or a flight plan being sent, or if we get a look across the room, the maintenance coordination team could be working on an aircraft that's broke or needs to be routed a certain way. Can you just read down those three columns of functions? Sure. So we've got the aircraft routing team, airport customer service. We've got catering, cargo, charters, corporate communications, corporate security,
Starting point is 00:37:58 both crew teams, crew tracking, crew scheduling. We have our maintenance control manager that sits up on the bridge, the reservations, revenue management, and system operations managers that are managing the fleets. And this guy whose shoulder we're kind of looking over, he's got, looks to be one, two, three, four, five, six, seven monitors at least. What's he doing? Six monitors and one of the other, the seventh, as you mentioned, that's actually the phone system. Nevertheless, a lot of video that is presented to everybody in this room, a lot of information comes to them on these screens, whether it be just the alerting or they can just look at things to just monitor. He's got the weather viewer up there.
Starting point is 00:38:36 Does everybody always have the weather up? Because it's such a driver of our operational outlook and ultimately result. So, yes, there is a lot of video. We are working hard to reduce that footprint of monitors and try to present it in a more logical way, I'll call it. Just to be clear to someone who's listening, we're not anywhere near a flight tower. That's a common misconception when I say I work
Starting point is 00:39:01 at our operations and customer center. We're not in the airport. When I say, if you think of it as mission control at NASA, right away they go, oh, you work in the tower. No, I don't work in the tower. If you've seen Apollo 13, the movie, Mission Control, that's kind of the way this is set up. Apollo 13 was one mission, and we're running well over 3,000 missions a day. So that's the level of detail we have to put forth for every flight, every customer, every day. So this is our dispatch team. This is our strategic planning team. They're trying to maintain the schedule integrity of an irregular operation. I love that description. They're trying to maintain the schedule integrity of an irregular
Starting point is 00:39:42 operation. That describes airline business. It's very complex. Every day has something come up. No day just runs perfectly smooth. We'll certainly have 100% completion factor days, but that doesn't mean we didn't have to address, and I'm making this number up, you know, 5,000 disruptions of some degree. Coming up after the break, will even more technology make airline travel even safer?
Starting point is 00:40:10 And will technology ever replace the humans who fly the planes? The real big issue is production of pilots has slowed. I'm Stephen Dubner. This is Freakonomics Radio. We'll be right back. Okay, we're talking about how airline travel got so safe. And I want to get back to Billy Nolan, the acting administrator of the Federal Aviation Administration. I have to tell you, my oldest, I'm the youngest in a big family. My oldest brother was an Air Force pilot.
Starting point is 00:40:48 Oh, cool. Yeah, very cool. I didn't inherit any of the, I've asked him to explain to me over the years, many times, literally how it worked, the physics and the engine. And I can't, I just don't have the brain for it. There's always time. The world is in dire need of pilots. So, you know, Stephen, you may have an alternative career there. Well, I can assure you that my
Starting point is 00:41:09 eyesight alone will preclude me from that. But let me ask you, since you brought it up, the pilot shortage, how do you think about that from your perspective? There's a couple of dynamics in play. As a result of the pandemic, we have a large number of pilots who elected to retire. And at the same time, we didn't have at universities or flight schools the numbers that we needed, right? You could call that a sort of a perfect storm. But as a result of that, we've seen a real uptake in terms of what the airlines are doing on their side. They've established their aviation academies. And at the same time, on the government side, we're producing more designated pilot examiners.
Starting point is 00:41:53 It's the FAA who certifies them, right? Y'all get a license with my signature on it. So at the end of the day, we want to make sure that they're safe, they're ready to go. There is a shortage broadly in our country. A lot of it was driven by the pandemic because a lot of airline pilots retired. That, again, is Ed Bastian, the CEO of Delta. Delta alone, we had 2,000 pilots that we retired through an early incentive arrangement that we provided them. And the amount of training that takes to bring 2,000 new pilots in and the time it takes has created a long live recovery period. Then you have that same ripple effect going on throughout the industry because
Starting point is 00:42:31 we didn't have a lot of pilots on the streets and the military isn't producing as many pilots these days. Well, I'll speak to the military to civilian pipeline. And that again is Adam Yuhan, a former Air Force pilot who now flies for a major airline. Yes, that pipeline's gotten smaller. It's gotten smaller for a host of reasons. Obviously, the military has had some downsizing events. The real big issue is production of pilots has slowed. And this goes back to the very first point that we were talking about, the magic of
Starting point is 00:43:06 aviation and flight. The magic that attracted me and that blew me away as a little kid, I don't think it's out there as much as it was in the whole romance of flight and then the service aspect of wanting to be a military aviator. I think there's people who fear the military aviation thinking, I don't know if I have that service bone in my body. And the reality is I think a lot more people do have these kinds of things that they can bring to the table in aviation. And one of the things that I'm applauding is we're now reaching past the traditional communities because let's face it, aviation is predominantly a male dominated sport. And that is starting to be flipped on its head just a little bit. And you don't make a pilot overnight.
Starting point is 00:43:50 You can't go to a 10-week school and have a degree in aviation and go and fly as a captain for a major airline. That's not how it works. It takes years to get there. And that gets us into the economics of pilot creation because it is not cheap. Why would somebody pay $150,000 in student loans to become a pilot when they can pay $150,000 in student loans to become a lawyer and they walk out with a much better paying career in the beginning? Pilots do make good money eventually. At airlines like Frontier, Alaska, and Southwest, the first year salary for a captain ranges from around $180,000 a year to
Starting point is 00:44:27 $240,000. Although typically you don't start at captain, you start as a first officer or what used to be called co-pilot. At the bigger US airlines like Delta, United, and American, first year captain salaries are in the $300,000s. The problem is, as Adam Yuhan said, pilot training takes a long time and costs a lot of money. This wasn't always the case, and that too is connected to the rise of safety in commercial aviation. In 2009, a flight out of Newark, New Jersey, operated by Colgan Air, crashed on its approach into Buffalo, New York, killing all 49 people on board and one on the ground. The National Transportation Safety Board determined the crash was likely caused by pilot error, specifically the captain's inappropriate response to the activation of
Starting point is 00:45:17 the stick shaker, which led to an aerodynamic stall from which the airplane did not recover. The NTSB cited several other contributing factors, all related to crew or airline failures. In response to this crash, Congress mandated that all commercial airline pilots have at least 1,500 hours of flying experience. Until then, airlines could hire pilots with just 250 hours. The FAA says there is no quantifiable relationship between the 1,500-hour requirement and airplane accidents, but the fact remains that the Colgan crash was the last major commercial aviation crash in the U.S., and that was in 2009. This is an astonishing safety record produced, as we've been hearing today, by a
Starting point is 00:46:07 number of factors, including advances in aviation tech. I asked Adam Yuhan what he thinks the job of pilot will look like in a few decades. The generation that's currently employed at the airlines and the folks who are just starting their journeys, I think that they're going to be okay. I think that there is regulation in place, the contracts from the airlines to the unions, a lot of those jobs are protected. I don't know about after that. I don't know if we're going to start seeing a single pilot operation in some... How about a zero pilot operation? I don't ever want to think that way because I don't know. I love the idea of self-driving cars and the
Starting point is 00:46:45 Hyperloop, but I also know because I've seen it where the machine does something that just doesn't make sense. When you say you've seen it, what do you mean? I've flown both Boeing and Airbus products, and I have seen both of those products do something that was unexpected. I've seen a system fail or a weather radar return come up and it looks nominal or not important. And you fly close to it and you're getting a moderate to severe level of turbulence or you're in icing that you didn't expect. And I don't know if our predictive technology is quite there yet. I'm not saying it won't be. I'm definitely not saying that because I do believe we will be able to figure all these things out. And that's great. That's progress. The other thing is, is your emotional response of getting on an airplane where there's no voice
Starting point is 00:47:34 that comes from the front. I don't know how many people are ready for that. I know I'm not. I want somebody to be able to, if the machine goes wrong, can at least shut the machine off and turn it back on again, control-alt-delete it back into correction? I never want to be on an airplane without a Delta pilot at the wheel. Ed Bastian again. Our planes do have a lot of autonomy. They are operated largely by technology, and pilots are there to manage the technology and intervene as necessary.
Starting point is 00:48:02 But there are other companies that are developing platforms where planes can be controlled through remote operation. And the argument is that they're safer. I won't get on one. And I think it's going to take quite a number of years before consumers will eventually be willing to get on one. Although a human pilot can override a confused computer, the primary cause of most fatal accidents is human error. This past January, there was a near miss at JFK Airport in New York City when two planes nearly collided on a runway. Delta Flight 1943 was getting ready to take off. Delta 1943, cancel takeoff clearance.
Starting point is 00:48:43 Delta 1943, cancel takeoff clearance. That's an air traffic controller telling the Delta flight to abort takeoff. There was another plane on its runway just 1,000 feet ahead. The pilots of that plane, an American Airlines jet, had made a wrong turn. All right, and the Delta 1943. Before we get to zero-pilot planes, the interim step is probably one pilot planes. After all, technology in the cockpit just keeps getting better. Adam Yuhan again.
Starting point is 00:49:14 The next generation of these airplanes, it's the Starship Enterprise that we're even further along the line. So you bring on this new technology that has made a safer weather radar, is far superior than it's ever been before. Traffic collision avoidance systems, ground proximity warning systems that we have. The fact that we now communicate when we're flying over the ocean, instead of listening to a high frequency radio that's spitting out static for seven hours, you basically have a text message system with somebody on the ground, which then keeps me from getting audio fatigue. So I am now less tired as I fly through the air. So when something bad does happen, I can react. It's an interesting point you raise about audio fatigue. I guess that's a case
Starting point is 00:49:56 where better technology lets you be better at doing the things that you do as a human. Are there other examples of technologies that you feel accentuate or highlight your human abilities? One that's very, very small, but for instance, some aircraft have what's called auto trim. So trim is the basic aerodynamic 101 here is a tab on parts of the airplane that you can trim off pressure so the airplane is easier to control or maneuver. Well, over the years, they have developed an auto trim system on some airplanes where there's no button for us to actually manually manipulate the trim tab and the computer does it for us. So now instead of me having to click, click, click, click, and move that trim tab as
Starting point is 00:50:43 I'm moving the stick, all I do is point the airplane in the position I want it to go, and it goes there. Now, people say, well, that's easy. Yeah, you're right. It's totally easy. But when you're flying into a really crowded airspace situation and you have weather, now you have little less to concentrate on. Those things do make you sort of superhuman because of your situational awareness, which is critical for pilots. Instead of it being taken away, your situational awareness now is expanded. You know where other airplanes are. You know what's happening on the runway. You understand all those kind of things. Let me ask you this, Adam. Are pilots normal people who happen to fly airplanes, or are you all sort of weirdos? A little from column A and a lot from column B.
Starting point is 00:51:28 I think when you meet us as a whole at a party, you'd know something was maybe a little different about that person. There's an old joke, how do you know that a fighter pilot's at your party is he'll tell you. And the reality is most pilots like to talk about aviation, especially when they're new and younger in the field. It kind of feels like part of who we are. And no matter how much we might try to deny that, it's kind of ingrained in our personality. Also ingrained in the pilot personality, from what I can tell, is an absolute obsession with safety. I think back to something my brother Joe, the former Air Force pilot, once told me.
Starting point is 00:52:10 We had just had a family reunion on the East Coast. He lives out West and he had flown in on his own plane. It is a tiny little experimental jet that he built. It's basically a motorcycle with wings. On the last night of the reunion, we were all having an early dinner together in the hotel restaurant. It was only around 5.30 or 6 p.m. and Joe stood up, said he had enjoyed the reunion, and now he was saying goodbye. And we all said, Joe, it's so early. What's your hurry? He said that he had several hours of flight planning ahead of him. And then he said, there are old pilots and there are bold pilots, but there are no old bold pilots. Here again is Adam Yuhan. I've done this for a long time. When I was younger, I sure as hell wanted people in the
Starting point is 00:52:58 military to appreciate what I was doing. And then when I got in the airline, I thought the same thing. But I realized after the years that go by, the best thing that can ever happen is I never make a highlight reel. Everything went smooth. I retire and I get a nice lithograph signed by my friends. The reality is, is things do run really smoothly. And that's why when people, the traveling public sees the hiccup, it is so eye gougingly painful because now all of a sudden you're delayed 25 minutes and it's like, think about it for a second. You're hurtling through the air at 530 miles an hour going from New York to Los Angeles. You're going to be there in less than five hours.
Starting point is 00:53:38 Less than 200 years ago, it took people 28 days or more to travel that same distance and most of them didn't make it. So I think the perspective is needed. And it's even needed for guys in the industry. Sometimes we need a little bit of that, too. I hate to say this because it does become a job sometimes, and you forget. My favorite thing about flying, it's still to this day, it's my favorite thing. It's when it's cloudy outside and you punch through the cloud layer and you get that first glint of sun.
Starting point is 00:54:03 It's still, it blows my mind every time I do it. Coming up next time in the third and final episode of Freakonomics Radio Takes to the Skies, it's time to sort out the economics. Airlines face incredibly volatile demand, and they have huge fixed costs. How do airlines make their money? Are tickets too expensive or too cheap? And what's it like to run a business where one of your major costs fluctuates wildly? When you have a commodity that's as volatile as fuel and you hedge on a longer term basis, it's very expensive. And what about the pollution from burning all that fuel?
Starting point is 00:54:46 That's next time on the show. Until then, take care of yourself and if you can, someone else too. Freakonomics Radio is produced by Stitcher and Renbud Radio.
