HAMPTON, Va. (AP) -- An Air Force leader says some F-22 Raptor pilots are asking to be moved into other jobs because of a series of oxygen-deficit problems aboard the stealth fighter.
The nation's F-22 fighter jets were grounded for four months last year after pilots complained about experiencing a lack of oxygen that can cause dizziness and blackouts. Air Force officials say they have taken steps to mitigate the problem, but they still haven't pinpointed what's causing the hypoxia-like symptoms. Hypoxia is when the body doesn't receive enough oxygen.
Gen. Mike Hostage, commander of the Air Combat Command at Langley Air Force Base in Hampton, Va., told reporters Monday that a small number of pilots have asked not to fly the jets or to be reassigned. Hostage didn't provide exact figures.
