"Is the Air Traffic Control System Broken?"
Release Date: September 5, 2025
Host: Stephen J. Dubner
Episode Overview
In this episode, Stephen Dubner explores the state of the U.S. air traffic control (ATC) system in the wake of several recent crises—including a tragic midair collision near Washington, D.C. and alarming equipment outages at Newark Liberty Airport. The episode digs into why, despite serious technological and staffing shortcomings, American air travel remains remarkably safe—and whether this luck is sustainable. The conversation brings together voices from airline leadership (Delta CEO Ed Bastian), former federal regulators, economists, and policy experts. The big questions: How did the ATC system get so outmoded? Why is reform so hard? And what should be done—before another disaster?
Key Discussion Points and Insights
1. The Scale and Safety of U.S. Air Traffic Control (02:07–06:11)
- ATC’s Hidden Role: Air traffic controllers guide over 45,000 flights carrying 3 million passengers daily in the U.S.—double the 1980s volume—but remain largely invisible to travelers.
- Exceptional Safety: The risk of a fatality in commercial air travel is about 1 in 13 million boardings, making flying 40 times safer than it was 50 years ago.
"The people who control the air traffic...they are hidden from sight. They are a sort of invisible hand ensuring our safe passage. Although, if something goes wrong, they stop being invisible."
— Stephen Dubner (03:04)
2. Recent Failures and Rising Warnings (03:40–06:11)
- D.C. Collision & Newark Outages: Fatal accident and communication blackouts reveal deep systemic cracks—controller errors, outdated equipment, and fragile infrastructure.
- Public Scrutiny and Fading Panic: Public concern spiked, then faded, despite systemic vulnerabilities remaining.
3. Airlines’ Perspective: Challenges with FAA & ATC (06:27–14:28)
- Ed Bastian (Delta CEO) on Modernization:
- FAA is simultaneously a partner and regulator, but lacks consistent capital, resources, or political support.
- Much of the ATC system still relies on technology from the 1950s and 1960s.
- Chronic staffing shortages lead to reduced flight capacity and longer travel times.
"They're a critical business partner, and they're our regulator...They have not had the capital...or the support...to execute with the level of quality that I think they would like to deliver to us."
— Ed Bastian (07:14)
"I'd say that you and I both have more technology in our car than we're able to use in our planes."
— Ed Bastian (11:32)
-
Delays and Demand: Summer storm patterns have worsened, congestion is up, airlines have to reduce schedules, and customer frustration is rising.
-
Outdated Infrastructure: Airlines have invested in airport terminals, but remain limited by airspace and ATC technology.
"Every day that goes by, we're getting one day closer to when the thing will break."
— Ed Bastian (14:28)
4. The Regulator’s View: FAA’s Complex Mission (15:13–23:08)
- Polly Trottenberg (former Deputy Secretary of Transportation/Acting FAA Administrator):
- FAA manages staggering complexity: commercial flights, military operations, and now commercial space launches—all dependent on both analog and advanced systems.
- Aging systems, like the NOTAM (Notice to Air Missions), have caused massive disruptions when failing.
- COVID-induced training hiatus and waves of retirements have exacerbated controller shortages.
"The FAA, in my opinion, is the largest, most complex, 24/7 safety critical operation in the federal government."
— Polly Trottenberg (18:14)
- Historical Roots: Many ATC systems rely on organizational and technical structures built after WWII.
5. Economics and Funding: Why Modernization Lags (26:29–38:41)
- John Strong (Economist, William & Mary):
- Deregulation in the ‘80s increased air travel dramatically, but ATC infrastructure did not keep up with demand.
- FAA operates with a mixed funding model—mainly from a user trust fund (ticket taxes), but capital investment is often subject to unpredictable Congressional appropriations.
- Most capital spending goes to maintenance, not modernization.
- Staffing shortages alone cost $135–$160 million per year in delays.
"We basically have an iPhone 5 when the rest of the world has an iPhone 18."
— John Strong (05:23)
-
Technology Gap: The U.S. lags behind in adopting satellite-based navigation (GPS), still relying heavily on radar.
-
AI & Automation: New tech could make controllers’ jobs more efficient, but the complexity of the airspace and one-off nature of each facility slows automation.
6. Staffing Crisis and Training Bottlenecks (20:24–35:50)
- Recruitment & Training: The U.S. has only one major controller academy (Oklahoma City); plans for other sites have been blocked by local interests.
- Difficulty of Transfers: Controllers must retrain for each new location’s unique airspace—even seasoned ones are treated as trainees when they relocate.
- Retention: Only about 75% of trainees complete the academy.
7. Budget Dysfunction and Congressional Micromanagement (38:41–41:09)
- FAA’s Budget Constraints: Critical funding for facilities and equipment is subject to Congressional discretion, making long-term planning impossible.
- Modernization Stalled: Unlike airports that receive mandatory, multi-year funding, FAA’s capital budget has remained flat for a decade—falling short of actual modernization costs.
"You have to step back and look at how the federal government budgets right now. I mean, talk about a system that has grown overly complicated and doesn't work very well."
— Polly Trottenberg (38:56)
8. Why Is U.S. Aviation So Safe—And Roads So Deadly? (41:09–43:19)
- Systemic Differences: Aviation is federally regulated, allowing for stringent safety oversight; road safety is highly decentralized, causing uneven outcomes.
- Lessons: Certain systemic improvements in roads could mirror aviation’s centralized safety processes, but political and logistical challenges persist.
9. Political Obstacles to Reform: Congress, Interests, and General Aviation (46:43–66:02)
- Dorothy Robine (Policy Scholar):
- ATC modernization is persistently blocked by Congressional micromanagement and interest-group politics—especially from general aviation and business jet lobbies.
- Both the Clinton and Trump administrations (and many other countries) have proposed "corporatizing" ATC—removing it from traditional regulatory agencies, enabling responsive management and independent capital investment, but Congress has blocked such efforts.
- General aviation, despite making up a small fraction of traffic, exerts enormous political pressure due to effective organization and Congressional caucus influence. Private pilots and business jets are undercharged relative to the costs they impose.
"This is effectively a business trapped in a regulatory agency and micromanaged by Congress."
— Dorothy Robine (05:33, also 56:45)
"A plane is a plane. If you're a controller and you've got an A321 and a business jet, they get equal treatment. The cost they impose on the system is identical."
— Dorothy Robine (66:13)
- International Models:
- Canada’s NAV Canada is cited as an efficient corporatized/coop utility model.
- Most advanced countries have corporatized ATC; the U.S. lags due to political inertia and lobbying.
Notable Quotes and Memorable Moments

On the System's Fragility:
"Every day that goes by, we're getting one day closer to when the thing will break."
— Ed Bastian (14:28) -
On Congressional Interference:
"You can't run a business out of a regulatory agency. But I really would fault Congress. They should know better."
— Dorothy Robine (46:54) -
On the Imbalance in System Contributions:
"The private jet, there's no ticket tax. There's no segment fee. All there is is a fuel tax of a couple of hundred dollars...$3,500 versus $327."
— Dorothy Robine (65:24) -
On International Best Practices:
"This is a piece of infrastructure that everybody else has figured out how to run better...It was obvious in 1995... Now close to 100 countries have done this."
— Dorothy Robine (55:39, 56:11)

Conclusion and Next Episode Preview
Dubner concludes that the U.S. air traffic control system, while statistically safe, is under immense and growing strain—operating on antiquated technology with chronic funding shortfalls and encumbered by political infighting. Calls for "corporatization" have evidence and worldwide success on their side, but reform remains stalled by congressional inertia and special interests, particularly in general aviation. The series will continue in the next episode, featuring even more stakeholder voices—including business jet representatives and air traffic controllers themselves.
This detailed summary provides a comprehensive walkthrough for newcomers and air travel veterans alike to understand the key problems, conflicts, and prospects in America’s air traffic system—and why it’s so hard to change.
