Wisk Aero, the electric air taxi company owned by Boeing, has been sued by a former employee, who claims she was fired after raising safety concerns.

Former software manager Briahna O’Neill sued Wisk in Santa Clara Superior Court earlier this week, alleging discrimination and wrongful termination. The Seattle Times first reported on the lawsuit, noting that Boeing declined to comment.

O’Neill said she filed two internal safety reports that described how Wisk had engineers reduce the amount of software testing required by the FAA to meet a test flight deadline in 2025. O’Neill claims she was fired just weeks after filing the second complaint.

Founded in 2019, Wisk is one of several companies trying to develop commercially viable electric vertical take-off and landing aircraft. It is one of the few companies working to achieve total autonomy. Wisk is also one of eight companies that were approved earlier this year by the FAA to join a three-year program to test such aircraft. Wisk said he cannot comment on ongoing litigation.
