Major Ryan Link and Captain Justin Grieve, the aircraft's two pilots and the only two aboard, were unable to regain control and safely ejected just as the aircraft stalled and mushed into the ground and its left wing impacted the ground. The $1.4 billion aircraft crashed just off the left side of the runway and exploded. It was the first-ever B-2 crash and followed 75,000 hours of loss-free service. Link and Grieve both suffered injuries during ejection, with Grieve suffering compression fractures to his spine.
The report points to the inaccurate readings as contributing factors, adding that ineffective communication of critical information about a technique used to remove moisture from the sensors also contributed. It's possible that all the maintenance crew had to do to avert the accident was turn on the pitot heat prior to performing air data calibrations. But the suggested technique was not part of checklist procedures.
