A Former Manager Claims Boeing’s Air Taxi Startup Bypassed Key Safety Tests to Meet Deadlines
Wisk Aero is trying to prove pilotless air taxis can safely carry passengers. A former employee just called that goal into question.
Boeing’s pilotless air taxi startup is facing a new lawsuit.
Wisk Aero, the autonomous aircraft company owned by Boeing, has been sued by a former software manager who says she was fired after filing internal safety reports warning that the company was reducing safety-critical software testing to keep a flight milestone on schedule.
Briahna O’Neill sued Wisk and Boeing in Santa Clara Superior Court on June 29, alleging discrimination, retaliation, and wrongful termination. The case says O’Neill filed two internal safety reports in early 2025, which claimed that Wisk engineers were being pushed to reduce FAA-required testing on the company’s sixth-generation aircraft. She says she was fired in March 2025, less than two weeks after the second report.
Wisk and Boeing declined comment.
A pilotless bet
While the allegations are as yet unproven, they cut to the center of Wisk’s pitch. The California-based company is trying to commercialize a fully autonomous, four-passenger electric air taxi, with no pilot onboard.
Wisk was formed in 2019 as a joint venture between Boeing and Kitty Hawk, the electric-aircraft startup backed by Google co-founder Larry Page. From the start, it took a different path from many air taxi rivals by aiming directly for an autonomous ride rather than initially launching with a piloted aircraft.
Sebastien Vigneron became Wisk’s CEO in 2025. Before that, he led Wisk’s Gen 6 program, including autonomy, airspace integration, software engineering, systems testing, flight testing, and program management. Former CEO Brian Yutko moved into a senior product development role at Boeing Commercial Airplanes and remains chair of Wisk’s board.
However, the lawsuit may matter more for Wisk than for Boeing. Richard Aboulafia, managing director at AeroDynamic Advisory, told Inc. he doesn’t view Wisk as central to Boeing’s business or public reputation, particularly because broad adoption of autonomy in air transport remains “a very long way off.”
Testing under scrutiny
O’Neill’s lawsuit focuses on the technical systems Wisk must prove to regulators. The case says she raised concerns about the company’s vehicle-management system, a software layer involved in controlling flight and navigation. It alleges Wisk reduced testing to stay on track for the first flight of its Gen 6 aircraft.
Wisk has made software validation central to its public case for autonomy. In 2024, the company acquired Verocel, a software verification and validation firm, saying the deal would help its effort to certify Gen 6. Then-CEO Brian Yutko said at the time that “high-integrity software development is critical” to certifying an autonomous electric aircraft.

Wisk says it has completed more than 1,750 safe test flights across six generations of aircraft and is now testing two Gen 6 aircraft in Hollister, California. In a July 1 blog post, the company described a “multi-layered validation ecosystem” for its autonomy stack, including software simulation, hardware-in-the-loop testing, and surrogate aircraft flights.
In a statement to Inc., the FAA said its priority in eVTOL certification is “ensuring the aircraft is safely designed and produced” through a multi-phase process that ends with type and production certificates. The agency said it works closely with applicants so they understand the standards they must meet and can “quickly address any deficiencies.”
Air taxis get ready to take off
The lawsuit comes as air taxis move from demos toward deployment. Earlier this year, the FAA selected Wisk as part of Texas’s project in the agency’s three-year eVTOL Integration Pilot Program. FAA Deputy Administrator Chris Rocheleau said the program would provide operational experience to help shape standards for safe advanced air mobility operations.
This week, rival Joby Aviation and Toyota announced a joint venture to prepare for commercial air taxi production, one which will start with a piloted aircraft. Wisk is betting that autonomy can eventually make air taxi service cheaper and easier to scale.
