Wendover’s Boeing Story Blames the Supply Chain, but the Evidence Points Back Inside Boeing
Wendover Productions' How Boeing Lost Its Way makes a persuasive broad argument: Boeing's problems are institutional, not a collection of unrelated manufacturing defects. But its explanation is too neat.
The documentary presents a story in which Boeing transferred development costs to suppliers, squeezed them until quality deteriorated, while Airbus pursued a fundamentally different strategy built around supply-chain stability.
There is truth in that account. But the evidence does not support its clean division. Boeing still carried most of the 787's development costs. Airbus used comparable outsourcing, risk-sharing and supplier cost-reduction strategies. And investigations into some of Boeing's most notorious failures point directly to decisions made inside Boeing itself.
Wendover credits Jon Ostrower and The Air Current for their reporting. My objection is not that the documentary invented Boeing's crisis. It is that its explanation simplifies the financial arrangements, overlooks important comparisons, and does not adequately distinguish the different mechanisms behind Boeing's failures.
The 787 was not financed primarily by suppliers
Wendover claims that 787 suppliers had to "foot the bulk of the upfront development costs."
That description exaggerates the financial transfer.
Boeing's own 2004 Form 10-K disclosed that suppliers had earned $205 million in development cost-sharing payments that year. Crucially, Boeing described these contributions as reimbursements for costs Boeing itself incurred in experimentation, basic design and testing. Boeing also retained the same rights to the aircraft components that it had under traditional supplier arrangements.
More importantly, Boston Consulting Group's 2016 analysis estimated that Boeing spent approximately $20 billion developing the 787, while supplier development costs were considerably lower.
The aircraft's development risk was shared, but Boeing remained responsible for the overwhelming financial commitment.

This distinction matters.
The 787's failure was not simply that Boeing persuaded suppliers to finance an aircraft while Boeing merely assembled it. Boeing spent billions developing the aircraft while distributing substantial design and manufacturing responsibilities across an international network.
That created a serious integration challenge. But it is a different problem from the one Wendover describes.
The relevant question is why Boeing could spend approximately $20 billion on a new aircraft and still fail to coordinate its development and manufacturing partners effectively.
Airbus did not avoid the same supplier model
Wendover makes an unusually sweeping claim:
"Airbus never pursued such an extractive strategy with its suppliers."
Airbus's own documentation contradicts that characterization.
Its 2014 Corporate Responsibility and Sustainability Report describes the A350's procurement strategy as an integrator model that outsourced much of the aircraft's design, manufacturing and subassembly.
Major suppliers received larger, more integrated work packages and shared development costs and risks with Airbus. Suppliers accounted for approximately 60% of the A350's aerostructure costs.
Airbus also established cost and schedule targets for those suppliers.

This was not fundamentally different from the broad supplier risk-sharing approach Wendover criticizes at Boeing.
The comparison becomes even less convincing when supplier pricing is examined.
Boston Consulting Group identified Airbus's SCOPE+ program alongside Boeing's Partnering for Success initiative. Both programs used procurement incentives, including opportunities for future contracts, to encourage suppliers to reduce prices on current work.

There were differences in how the manufacturers managed their suppliers. Airbus's A350 strategy emphasized earlier supplier involvement, more integrated work packages, shared processes and closer collaboration.
That distinction deserves investigation. It is not the same as claiming Airbus avoided outsourcing or supplier cost pressure.
In fact, Airbus subsequently moved in the opposite direction on selected manufacturing activities. An October 2025 IATA and Oliver Wyman report describes Airbus's strategy of bringing fuselage and wing manufacturing and assembly back in-house to improve control and quality.

A March 2024 Government Accountability Office investigation also found that both Boeing and Airbus struggled to increase production of their principal aircraft families. Nine of the 15 suppliers interviewed reported difficulties filling orders, while 15 of 17 manufacturers reported difficulties hiring sufficient skilled workers.
The GAO acknowledged that its stakeholder sample was not statistically representative, but the findings establish that industry-wide workforce and material shortages were real.

None of this establishes that Airbus had Boeing's safety problems. It establishes something more limited but important: Airbus is not the clean alternative the documentary presents.
The meaningful comparison is how effectively each manufacturer managed its suppliers, maintained engineering control and protected quality.
The 737 MAX crisis involved decisions beyond one defective sensor
Wendover correctly identifies the MCAS system's dependence on a single angle-of-attack sensor as a critical vulnerability.
But its explanation does not adequately examine the decisions surrounding that system.
The US House Committee on Transportation and Infrastructure's September 2020 investigation documented extensive financial and schedule pressure throughout the MAX program.
Among its findings:
- Boeing reduced avionics regression-testing work by 2,000 hours.
- It examined additional cost reductions involving 3,000 hours of flight-test support and 8,000 hours of engineering flight-deck simulator work.
- The FAA accepted Boeing's cost-based argument against installing an Engine Indicating and Crew Alerting System.
- Boeing marketed the MAX on the promise that existing 737 NG pilots would require minimal, non-simulator-based differences training.
- Boeing rejected a proposed MCAS indicator light.
- Boeing withheld important MCAS information from the FAA, customers and pilots, including internal test information about the time required for a pilot to recognize and respond to an uncommanded activation.
These were not simply consequences of a difficult supplier relationship.
They were engineering, testing, certification and communication decisions made within Boeing, alongside failures of regulatory oversight.
The single-sensor vulnerability was the technical trigger. But it was not the entire explanation for why the aircraft entered service with such a dangerous system.
A documentary that reduces this crisis primarily to engine size and a software workaround leaves out the decisions that made the workaround so dangerous.
The door-plug investigation points directly to Boeing's factory
The strongest subsequent evidence comes from the National Transportation Safety Board's final investigation into Alaska Airlines Flight 1282.
The report was published in June 2025, after Wendover's February 2024 video. It provides information that substantially sharpens the explanation of Boeing's manufacturing failures.
The four bolts securing the aircraft's mid-exit door plug were installed before the fuselage reached Boeing's Renton production facility.
Five rivets installed by a Spirit AeroSystems supplier required corrective work. Spirit personnel at Renton were responsible for repairing those rivets.
To provide access, Boeing personnel opened the door plug, necessarily removing its four securing bolts.
What happened next exposed a catastrophic failure of Boeing's internal production controls.
The NTSB found that:
- No required removal record was generated when the door plug was opened.
- Personnel responsible for the door operation lacked experience with opening the plug.
- No door-team personnel were on duty when the plug was closed.
- The absence of a removal record meant no quality-assurance inspection of the closure occurred.
- Boeing's relevant work instruction had a documented history of compliance problems extending back at least ten years.
- Boeing received 35 employee Speak Up reports concerning the parts-removal process between January 2019 and April 2024.
The NTSB identified Boeing's inadequate training, guidance and oversight as the probable cause. It identified ineffective FAA surveillance and audit planning as a contributing factor.
Sources: NTSB Aviation Investigation Report AIR-25-04 and NTSB's June 24, 2025 findings.
There is an important distinction here.
Spirit's supplier installed rivets that required rework. That was part of the chain of events. But the four missing bolts were not delivered to Boeing in a missing condition. They were removed during Boeing's own manufacturing process.
The NTSB could not identify the individual who physically opened the plug. It did, however, establish the failures in Boeing's process that allowed the aircraft to leave the factory without the bolts or the required inspection.
This is not merely a story about suppliers failing to deliver good components.
It is a story about a manufacturer that could not reliably document, supervise and inspect work performed inside its own production facility.
Boeing's Spirit divestiture and subsequent reversal
Wendover also misstates an important financial transaction.
It says Boeing and its shareholders received a $1.2 billion check when the Wichita and Tulsa operations were sold in 2005.
Boeing's own second-quarter 2005 financial announcement records approximately $900 million in cash received from Onex, together with the transfer of approximately $100 million in liabilities.
The transaction also established long-term supply agreements that provided Boeing with ongoing cost savings. Boeing recorded a $110 million pre-tax charge and anticipated another $238 million pension-related charge.
Source: Boeing's Second-Quarter 2005 Results, SEC filing, July 27, 2005.
The sale was real and strategically consequential. But it was not the $1.2 billion cash payment described in the documentary.
There is now an even more interesting development.
On December 8, 2025, Boeing completed its acquisition of Spirit AeroSystems, bringing its Boeing-related commercial manufacturing operations back under its control.
Boeing's 2025 SEC filing reported total consideration of approximately $8.371 billion. This included $4.704 billion in Boeing stock, $948 million in debt repaid, and $2.571 billion in loans, advances and other payments, among other items. The latter amount included funding for Spirit's concurrent transaction involving its Airbus-related assets.
These figures are not directly comparable with the 2005 sale price. They represent different transactions and different financial obligations.
But the strategic reversal is unmistakable.
Boeing's own stated rationale was to align commercial production systems, safety and quality management systems, and workforces around the same priorities and outcomes.
Source: Boeing 2025 Form 10-K, SEC filing.
The company that once separated these operations is now trying to restore direct control over them.
That does not prove that every manufacturing failure resulted from the original divestiture. It does demonstrate that the independent supplier arrangement did not provide the stability and alignment Boeing ultimately wanted.
Boeing still has not completed its recovery
The latest financial results provide another useful test.
In its October 27, 2026 third-quarter results, Boeing reported a commercial-aircraft operating loss of $1.582 billion for the first nine months of the year, compared with $6.447 billion over the same period in 2025.
Deliveries improved from 440 to 475 aircraft.
The 737 program was still progressing toward stabilized production of 47 aircraft per month, while the 787 was producing eight per month.
Boeing also reported a commercial-aircraft backlog exceeding 6,300 aircraft, valued at approximately $612 billion.
Source: Boeing Third-Quarter 2026 Results, October 27, 2026.
The improvement is substantial. It would be inaccurate to suggest that Boeing has made no progress.
But demand is not the problem. The company has enormous demand for its aircraft.
Its continuing challenge is converting that demand into reliable, repeatable and profitable production.
Reintegrating Spirit is one part of that process. It is not proof that the underlying engineering, management and quality-control problems have been solved.
The verdict: Boeing failed to govern the system it controlled
Wendover's conclusion that Boeing has a systemic problem is credible. Its explanation is less convincing.
The documentary repeatedly brings different problems under one broad explanation: financial pressure, supplier exploitation and outsourcing.
But these are not interchangeable.
The 787 involved fragmented engineering and manufacturing responsibilities, alongside substantial development spending by Boeing itself.
The Airbus comparison overlooks similar outsourcing, supplier risk-sharing and cost-reduction arrangements.
The MAX involved identifiable engineering, testing, training, certification and disclosure failures.
The Alaska Airlines door-plug incident exposed failures in Boeing's own factory procedures, employee training, documentation and quality assurance, compounded by inadequate FAA oversight.
The supplier model mattered. Financial pressure mattered. But neither replaces the need to establish exactly which decisions caused each failure.
I would make a more specific accusation.
Boeing took responsibility for building some of the most complicated machines in the world, but repeatedly failed to govern the people, processes, suppliers and safety systems required to build them properly.
It sold critical manufacturing capabilities, created a more complicated network of dependencies, failed to maintain effective control over that network, and eventually began buying essential operations back.
That is a more serious indictment than simply saying outsourcing ruined Boeing.
The company did not lose its ability to design extraordinary aircraft overnight. It lost the ability to consistently manage the industrial system responsible for turning those designs into safe, reliable products.
And that is the responsibility no supplier, contractor or regulator can carry on Boeing's behalf.
