The Engineers Knew

The people who build the airplane know what they're doing. That is what you believe when you board a flight. It is what 346 people believed.

Cedric Atkinson

In 2017, Boeing spent $9.2 billion buying back its own stock. It spent $3.2 billion on research and development. The year before the first crash, the company put nearly three times more money into making its shares expensive than into making its planes.1

$9.2B Stock buybacks, 2017
$3.2B Research & development, 2017

Between 2013 and 2019, Boeing returned $43.4 billion to shareholders through buybacks alone. That was 104 percent of its total profits during the period. Every dollar the company earned went back to Wall Street, and then some.2

On October 29, 2018, Lion Air Flight 610 crashed into the Java Sea thirteen minutes after takeoff. All 189 people on board died.3 On March 10, 2019, Ethiopian Airlines Flight 302 crashed six minutes after takeoff. All 157 people on board died.4 Same aircraft model. Same system failure. Same cause.

346 people. Two crashes. And between them, the company that built the plane declined an urgent request from the second airline's chief pilot asking how the system worked.5

Everyone knows this story. Or they think they do. It gets told as a greed story. Executives chose profit over safety. Stock price over engineering. Shareholders over passengers. That version is emotionally satisfying. It is also incomplete. The problem was not that Boeing's leaders were greedy. The problem was structural. The people who had the knowledge had no power. The people who had the power bore no consequences. And the people who bore the consequences had no knowledge at all.

Three groups, no overlap. That separation is the mechanism.

The merger

In August 1997, Boeing acquired McDonnell Douglas for $13 billion.6 Boeing was the surviving company. But McDonnell Douglas executives filled the key positions. Harry Stonecipher, the former McDonnell Douglas CEO, became Boeing's president and chief operating officer. Ron Woodard, who ran Boeing's commercial airplane division, later described it this way: "Harry outsmarted Phil and his gang bought Boeing with Boeing's money."7

Stonecipher did not hide what he was doing. In 2004, he told the Chicago Tribune:

When people say I changed the culture of Boeing, that was the intent, so that it's run like a business rather than a great engineering firm. Harry Stonecipher, Boeing President, Chicago Tribune, February 29, 2004

Before the merger, Boeing engineers had authority. One retired engineer described the old culture simply: "As an engineer, I had a lot of authority to do the right thing."8 After the merger, accountants made the decisions. Short-term financial metrics replaced long-term technical judgment. Stonecipher's phrase for this was "passion for affordability." The engineers called it something else.

In September 2001, Boeing moved its headquarters from Seattle to Chicago. The CEO, Phil Condit, explained the rationale: "As long as we are side-by-side with commercial airplanes, the view always is that's what we're about."9 A thousand jobs relocated. The top 500 executives were given what Boeing internally described as "greater separation" from the production plants.10

Greater separation. That was the stated goal. Leadership would operate at a distance from the people who built the planes. The engineers would remain in Seattle. The executives would be in Chicago. The knowledge would be in one place. The power would be in another.

When Condit resigned in 2003 amid a procurement scandal, the board did not promote Alan Mulally, who had led the successful 777 program. They brought Stonecipher out of retirement.11 When Stonecipher left in 2005, they did not look inside the company. They recruited Jim McNerney from 3M. McNerney was a former GE executive. A Jack Welch protege. He had no aerospace engineering background. By the time he retired, he had earned approximately $239 million, with compensation tied to share performance.12

McNerney made the decision that produced the 737 MAX. In the summer of 2011, Airbus was taking orders for the A320neo, a re-engined version of its existing narrowbody jet. American Airlines, a long-time Boeing customer, ordered 260 Airbus jets.13 Boeing had two options: design a clean-sheet replacement, which would have cost $10 to $12 billion and taken five to eight years, or bolt larger engines onto the existing 737 airframe, which would cost a fraction of that.14

They chose the engines.

The patch

The new engines were bigger. The 737 sits low to the ground. The larger engines had to be mounted further forward and higher on the wing. This changed the aircraft's aerodynamic behavior: at high angles of attack, the nacelles themselves generated lift, pushing the nose up. Previous 737 models did not do this.15

Boeing's solution was software. They designed a system called the Maneuvering Characteristics Augmentation System, or MCAS. When a sensor detected too high an angle of attack, MCAS would automatically push the nose down. The purpose was to make the MAX handle like the older 737 NG, so that pilots already certified on the NG could fly the MAX with minimal retraining. One hour on an iPad. No simulator time required.16

That was the business case. If the MAX flew like the NG, airlines could deploy it immediately. If it required significant new pilot training, the cost advantage over the A320neo would narrow. MCAS existed to protect a sales pitch.

The original design activated MCAS based on two inputs: angle of attack and G-force. It could move the stabilizer 0.6 degrees. During flight testing in 2016, engineers discovered the same pitch-up problem at low speeds. They removed the G-force trigger and quadrupled the authority to 2.5 degrees.17

MCAS authority evolution Original design: 0.6 degrees (two-input trigger)
After flight testing: 2.5 degrees (single-sensor trigger)
Maximum stabilizer deflection: ~4.7 degrees
Two cycles of the revised MCAS could push the stabilizer to its physical limit

The system now relied on a single angle-of-attack sensor. If that sensor failed, MCAS would activate on bad data. It could fire repeatedly. Each time a pilot trimmed the nose back up, MCAS would reset and push it down again. Effectively unlimited authority over the aircraft's pitch.

Boeing did not update the safety analysis it had submitted to the FAA. The document the regulator relied on still reflected the original 0.6-degree authority.18

An internal meeting in June 2013 had already set the strategy. Minutes show Boeing officials decided to portray MCAS as a modification to an existing system, not as something new. The internal rationale was explicit: "If we emphasize MCAS is a new function there may be greater certification and training impact."19 In 2016, Boeing's chief technical pilot emailed a request to strip MCAS from the pilot manual.20 In 2017, he asked the FAA to remove any mention of MCAS from the report used to develop training standards. The FAA agreed.21

The pilots who flew the 737 MAX did not know MCAS existed.

Boeing also made the angle-of-attack disagree alert a paid option. An indicator that would have told pilots their sensors were giving conflicting readings. Airlines could buy it for extra. Neither Lion Air nor Ethiopian Airlines did. The alert was inoperable on 80 percent of the active 737 MAX fleet. Boeing did not tell anyone.22

The signals

The feedback existed. Boeing had every signal it needed. The signals were generated inside the company, by people who worked there, through the company's own processes. They did not reach the people who made decisions. The signals were not weak. The structure suppressed them.

In November 2012, Boeing ran simulator tests. One pair of technical pilots responded to an uncommanded MCAS activation in four seconds. A second crew took more than ten seconds and judged the failure scenario "catastrophic."23 Federal guidelines assume pilots will respond within four seconds. A ten-second response time triggers a different hazard classification, one that requires additional design safeguards. Boeing submitted the four-second result to the FAA. The House Transportation Committee later found "no evidence" that Boeing shared the ten-second result with the regulator, with airlines, or with pilots.24

In December 2015, an engineer in Boeing's FAA-authorized certification unit emailed a question: "Are we vulnerable to single AOA sensor failures with the MCAS implementation or is there some checking that occurs?" The question went through internal channels. No design change followed.25

In 2016, Mark Forkner, Boeing's chief technical pilot for the 737 MAX, ran MCAS in the flight simulator. He messaged a colleague:

It's running rampant in the sim on me. I'm levelling off at like 4000 ft, 230 knots and the plane is trimming itself like craxy. I'm like, WHAT? Mark Forkner, Boeing Chief Technical Pilot, 737 MAX, text message, 2016

And then: "So I basically lied to the regulators (unknowingly)."26

Forkner had not been told the system had changed. He had presented the original MCAS specifications to foreign regulators. Now he was discovering, in a simulator, that the system he had described no longer existed. He bragged about having used "Jedi mind tricks" on regulators. But the messages reveal something else: he did not know what MCAS had become.

In June 2018, Ed Pierson, a senior manager at Boeing's 737 factory in Renton, Washington, emailed the general manager of the 737 program, Scott Campbell. Workers on the production line were pulling mandatory overtime. Some had worked more than five consecutive weeks without a day off. Parts were chronically short. Work was being done out of sequence. Pierson wrote: "For the first time in my life, I'm sorry to say that I'm hesitant about putting my family on a Boeing airplane."27

He recommended shutting down the production line. In a meeting weeks later, Pierson referenced his military background and said he had seen operations shut down for far less.

Well, the military's not a profit-making enterprise. Scott Campbell, 737 General Manager, to Ed Pierson, July 2018

Pierson retired in August 2018. Lion Air crashed less than three months later.28

Curtis Ewbank, a Boeing systems engineer on the 737 MAX, filed an internal ethics complaint. He had proposed a synthetic airspeed system that would cross-check multiple sensors. An executive rejected it on cost grounds. Ewbank later said a manager told him: "People have to die before Boeing will change things."29

A different Boeing employee, in an internal communication released during the investigation, described the aircraft this way: "This airplane is designed by clowns, who in turn are supervised by monkeys."30

Every one of these signals came from inside Boeing. From engineers, test pilots, factory managers, and technical staff. People with direct knowledge of the problem. Not one of them had the authority to stop it.

The crashes

Lion Air Flight 610 took off from Jakarta at 6:20 a.m. on October 29, 2018. A faulty angle-of-attack sensor fed erroneous data to MCAS. The system activated more than twenty times, pushing the nose down. The pilots fought it each time, trimming the nose back up. Each manual correction caused MCAS to reset and fire again. Thirteen minutes after takeoff, the aircraft hit the Java Sea at approximately 450 miles per hour. All 189 people on board were killed.3

The day before, the same aircraft had experienced the identical malfunction on the previous flight. An off-duty pilot riding in the cockpit jump seat identified the problem and told the crew to cut power to the electric trim system. The plane landed safely. The aircraft was returned to service the next morning with a different crew.31

After the crash, Boeing publicly named MCAS for the first time. The FAA issued an emergency directive. Boeing promised a software fix "in a few weeks." The fix was not completed by March.32

Ethiopian Airlines' chief pilot reached out to Boeing with an urgent request for information about the system. Boeing declined to respond. The company had proactively contacted American airlines and pilots. It did not respond to the Ethiopian request.5

On March 10, 2019, Ethiopian Airlines Flight 302 took off from Addis Ababa. A damaged angle-of-attack sensor, likely struck by a bird during takeoff, sent erroneous data. MCAS activated. The pilots followed the runaway stabilizer procedure and cut the system off. Then, unable to move the stabilizer manually at their speed, they turned it back on to get electrical power. MCAS immediately re-engaged. Six minutes after takeoff, the aircraft crashed near the town of Bishoftu. All 157 people on board were killed. They represented 35 nationalities, including 22 United Nations staff members.4

China grounded the 737 MAX the next day. Indonesia, Singapore, the European Union, Australia, and dozens of other regulators followed within 48 hours. The FAA, on March 11, issued a notice affirming the aircraft was safe to fly. It reversed that position on March 13, becoming the 52nd aviation authority to ground the plane.33

The consequence that never arrived

In January 2021, the Department of Justice charged Boeing with conspiracy to defraud the FAA. Under a deferred prosecution agreement, Boeing paid $2.5 billion: a $243.6 million criminal penalty, $1.77 billion in airline compensation, and $500 million for the victims' families. The agreement explicitly exonerated senior management.34

Mark Forkner was the only individual criminally charged. Four counts of wire fraud. His trial lasted less than a week. The jury deliberated for less than two hours and returned a verdict of not guilty on all counts.35

Judge Reed O'Connor, after the acquittal, said Forkner was "certainly not innocent" but agreed with the jury that he was not guilty. He called him a scapegoat. Forkner's defense attorney put it differently: "This was a massive corporate failure, and Boeing simply needed someone to pin it on."36

Dennis Muilenburg, the CEO who oversaw both crashes, was fired in December 2019. He left with $62.2 million in accumulated compensation. Pension, stock awards, salary, perks. He was not charged.37

No Boeing executive was criminally charged. No one went to prison. For 346 deaths.

Then the consequence failed to arrive again.

On January 5, 2024, a door plug blew out of an Alaska Airlines 737 MAX 9 at 16,000 feet. Two seats where the plug had been were empty. No one was killed.38 The Department of Justice determined Boeing had breached the deferred prosecution agreement.39

On March 9, 2024, John Barnett, a Boeing quality control manager who had spent 32 years at the company, died in a parking lot in Charleston, South Carolina. He was in the middle of giving a deposition in his lawsuit against Boeing. He had alleged that managers pressured workers not to document defects. He had found metal shavings lodged near flight control wiring. His death was ruled a suicide.40

On May 29, 2025, the Department of Justice dropped the criminal prosecution. It reached a non-prosecution agreement instead.41

On November 6, 2025, Judge O'Connor dismissed the case at the government's request. He wrote that the victims' families "are correct" that the agreement "fails to secure the necessary accountability to ensure the safety of the flying public." He wrote that he "disagrees with the Government that dismissing the criminal information in this case is in the public interest." But he said he lacked the authority to deny the dismissal.42

The same judge who called Forkner a scapegoat in 2022 was forced to dismiss the entire case in 2025. The families have appealed to the Fifth Circuit. The briefing schedule has been set.43

The consequence has not arrived. It is not arriving.

The structural finding

The table has a name. The separation it describes, where the people with knowledge have no power and the people with power bear no consequences, is the condition that determines whether a system corrects its own errors.44 Sowell called the people who bear the cost of their own decisions "residual claimants." They self-correct because errors cost them something. The cost produces a change. Insulated decision-makers do not self-correct because feedback never reaches them in a form that forces change.45

Boeing's executives were not residual claimants. The most dangerous institutional design places decision-making power far from the relevant knowledge. When power sits where the knowledge is not, errors compound without correction until the system collapses.46

Group Knowledge Power Consequence
Engineers Had it None Career risk for speaking up
Test pilots Had it None Forkner charged as scapegoat
Executives Chose not to acquire it Total Muilenburg left with $62.2M
FAA Diminished Ceded to Boeing Agency credibility damaged
Passengers None None 346 dead

The engineers who raised concerns about single-sensor MCAS were told not to upset executives. The test pilot who found a "catastrophic" failure scenario watched Boeing submit the passing result instead. The factory manager who recommended shutting down the line was told the military is not a profit-making enterprise. The systems engineer who proposed a cross-checking sensor was overruled on cost. In every case, the person with the knowledge lacked the authority to act on it.

The executives who chose single-sensor MCAS, who rejected the synthetic airspeed study, who overruled the factory shutdown request, who stripped MCAS from the pilot manual, who sold the safety alert as a paid upgrade, who certified 96 percent of their own work with 1,500 Boeing employees overseen by 45 FAA staff. These are the people who had the power. None of them bore the consequence.47

The consequence landed on people who had never heard of MCAS. Who boarded a flight on an October morning in Jakarta or a March morning in Addis Ababa. Who carried one assumption, the same assumption everyone carries. That the people who built the airplane know what they are doing.

This is not a greed story. Greed is a motive. Motives do not explain institutional failure. Thousands of companies are run by people who want to make money. Most of them do not produce 346 deaths. What produced these deaths was a structure in which no feedback loop connected the decision to its outcome. The CEO who chose the $1 billion re-engine over the $10 billion clean-sheet did not fly on the plane. The executive who rejected the second sensor did not sit in row 14. The board that approved $9.2 billion in buybacks in the year before the crash did not breathe the cabin air.

At Toyota, any worker on the production line can pull a cord and stop the entire operation for a single defect.48 The person closest to the problem has the authority to act on it. Knowledge and power occupy the same location. When Toyota faced its own crisis in 2010, nine million vehicles recalled for unintended acceleration, the error-correction mechanisms held. The company accepted responsibility, enhanced its quality systems, and recovered within three years. Boeing's response to the 737 MAX was to blame the pilots, minimize the system's role, and delay.49

The difference is structure. Toyota designed a system where the person who sees the problem can stop the line. Boeing designed a system where the person who sees the problem is told not to rock the boat.

Sowell's framework predicts the outcome with precision. When decision-makers are insulated from consequences, errors do not shrink. They compound. Without feedback mechanisms that impose real costs for being wrong, the system degrades until it collapses or is forcibly reformed.46

Boeing has not been forcibly reformed. The criminal case has been dismissed. The executives have kept their money. The families are still in court. The appeal is still pending. The structure that produced 346 deaths is, as of this writing, intact.

The engineers knew. They always knew. The structure made sure it did not matter.

New pieces when they're ready. Nothing else.
