Virgin Galactic’s recently fired flight test director claims that pilot error, not upper-level winds, resulted in the company’s SpaceShipTwo vehicle flying outside of its assigned airspace during a July 11 suborbital flight test that carried the company’s billionaire founder, Richard Branson. He suggested an independent investigation instead of a company-led one might be required to address the mishap.

Mark Stucky, who Virgin Galactic fired eight days after Branson’s flight, said his former employer put out an inaccurate statement about why VSS Unity flew unauthorized into Class A airspace for 1 minute 41 seconds during its descent. Class A airspace is primarily used by airlines, cargo operators and higher performance aircraft.
