Briahna O’Neill believed in the mission. She joined Wisk Aero in 2022 as a software manager. Three years later she was gone. Fired, she says, weeks after she filed internal reports warning that executives were pressing engineers to cut corners on FAA-mandated testing of flight-critical code.
The lawsuit filed this week in Santa Clara Superior Court lands at a delicate moment. Wisk, fully owned by Boeing since 2023, has logged more than 1,750 test flights. It flew its Generation 6 autonomous eVTOL for the first time in late 2025. The company touts the aircraft as a four-seat, 90-mile-range air taxi that needs no pilot on board. Certification and passenger service remain years away. Yet the allegations echo familiar questions about schedule pressure, software quality and whether voices that raise safety flags are truly heard.
O’Neill’s suit, first reported by The Seattle Times, details a vehicle management system described internally as “spaghetti code.” The disorganized programming, her complaint says, made it hard to trace failures or complete required verification. When she asked for more time in late 2024, leadership pushed back. One executive suggested two shifts and weekend work to keep the first-flight target intact. Her proposed schedule, the messages showed, would simply take too long.
Internal warnings meet swift pushback
In February 2025 O’Neill filed her first safety report. It flagged that the vehicle management system software did not appear to meet FAA testing standards. A second report followed in March. That one accused executives of deliberately reducing the amount of testing to hit the 2025 flight deadline. Less than two weeks later she was terminated. Her manager cited an “environment that hinders collaboration” and “inefficiencies and program delays,” according to court records.
“I spent years at Wisk believing in the company’s mission and in the future of this technology,” O’Neill said in a statement to The Seattle Times. “When I raised safety concerns to the company, I did so because I believed it was the right thing to do, not just for myself but for every passenger who would one day fly with this technology. Wisk’s response was not one of accountability. It was retaliation.”
The firing triggered unease inside the company. Screenshots included in the lawsuit show employees sending messages to senior leaders defending O’Neill’s leadership and warning that her exit could chill future safety reporting. One senior engineer wrote to then-CEO Brian Yutko: “Our software is in a terrible state. … The hardware teams may be on track for first flight, but software very much is not.”
Another employee drafted a letter urging leadership to encourage “constructive challenge … to the status quo” and to keep an environment “where all voices are heard, especially as related to safety.” In private chats, engineers expressed doubt. “I was trying to have faith but now I’m lost,” one wrote. The reply: “what are we doing here?” The answer that followed: “taking Boeing’s money.”
O’Neill also alleges gender discrimination during her time at Wisk. She filed a complaint with California’s Civil Rights Department shortly after her March 2025 termination. The agency issued a right-to-sue letter. Her current lawsuit seeks compensation but does not ask for reinstatement.
Wisk did not respond to multiple requests for comment from The Seattle Times or TechCrunch. Boeing declined to comment on the litigation. Yutko no longer serves as Wisk’s CEO. He now holds the role of vice president of product development for Boeing commercial airplanes while remaining chair of Wisk’s board.
The episode arrives against a backdrop of prolonged scrutiny of Boeing’s safety practices. Federal panels and congressional hearings have repeatedly highlighted gaps between management rhetoric and frontline experience. Wisk’s public materials strike a different tone. Its website declares, “Safety is our cornerstone. Safety is everyone’s responsibility. We speak up and celebrate tough choices that support a strong safety culture. We clearly communicate risks so they can be addressed and mitigated.” Company values also stress integrity, transparency and honoring commitments “even when it’s hard.”
Yet the autonomous air-taxi sector operates under intense timetable pressure. No eVTOL has received full FAA certification for passenger service. Earlier this year the agency launched a pilot program pairing developers, including Wisk, with state governments to accelerate testing. Wisk aims to certify its aircraft by the end of the decade. It has positioned full autonomy, with human oversight from the ground, as the path to safety, scale and lower costs. The company and the Texas Department of Transportation were selected by the White House in March 2026 to help lead safe introduction of such operations.
But autonomy raises the stakes on software. The vehicle management system controls flight and navigation. Integration of ground-control and air-control elements proved messier than expected when O’Neill’s team began work in fall 2024. Disorganized code, she alleged, increased the chance that defects would go undetected. Cutting test scope to preserve a deadline therefore carried direct implications for airworthiness.
Industry observers note the pattern feels familiar. Past Boeing whistleblower accounts, from the 737 MAX era through recent production-quality disputes, have centered on schedule overriding engineering judgment. Regulators have demanded cultural change. Whether those lessons have reached every corner of Boeing’s growing portfolio of future-mobility businesses remains an open question.
O’Neill’s case adds one more data point. It also highlights the tension inside startups absorbed by large manufacturers. Funding from Boeing, including a $450 million round and earlier joint investment with Kitty Hawk, gave Wisk stability. It also tied the young company’s cadence to the parent’s expectations. First flight of the Generation 6 vehicle occurred in December 2025, on or near the timeline that O’Neill says required trimmed testing.
Since then Wisk has flown a second Gen 6 aircraft and continues expanding its test program. The company stresses that its systems are designed to meet or exceed commercial-aviation safety standards. Public statements celebrate the pace of execution. Yet the internal messages cited in the lawsuit suggest not everyone shared that confidence in the software’s readiness.
The litigation will now move through discovery. Regulators may take notice. The FAA’s ongoing oversight of Boeing already includes close examination of safety culture and quality systems. Any findings that similar pressures exist at Wisk could complicate certification efforts across the eVTOL sector.
For now the dispute stands as a reminder. Technical ambition in advanced air mobility is real. So are the human and organizational challenges required to deliver on it. Promises of safer, cleaner flight depend on more than flight hours accumulated. They rest on whether engineers and managers can surface problems early, fix them thoroughly and do so without fear that candor will cost them their jobs.
So far Wisk has offered no public defense beyond silence. O’Neill has offered a detailed complaint, supporting messages and her own statement. The court will sort the claims. The industry, and passengers who may one day ride these autonomous taxis, will watch the outcome closely.
