F-22 crash not related to oxygen

HAMPTON, Va. (WAVY) - The Air Force says there is no indication Thursday's F-22 Raptor crash in Texas is related to the recent oxygen supply incidents.

The pilot ejected safely. Investigators say the pilot was on a routine training mission when he sent an in-flight emergency call before crashing a quarter mile east of the runway at Tyndall Air Force Base.

10 On Your Side was one of the first to report the problems with the F-22 Raptors. Many are based at LangleyAir Force Base in Hampton. The oxygen system causes some pilots to get dizzy or black out, although the exact cause has not been determined. The Air Force grounded the fleet for four months last year.
