LOS ANGELES - An Air Force investigation has found that the fatal crash of an F-22 jet fighter in California occurred after the pilot almost lost consciousness in a high-gravity manoeuvre.
The Air Force says the March 25 accident occurred as Lockheed Martin test pilot David Cooley was performing tests under high gravitational forces 56 kilometres outside Edwards Air Force Base.
The investigation board determined that during the third test he appeared to have been subjected to increased physiological stress and his lack of awareness delayed a recovery manoeuvre.
Cooley attempted a recovery, then determined he had inadequate altitude and ejected. But the report says he suffered fatal blunt force trauma due to the aircraft's speed and windblast.
The report issued by the Air Force Materiel Command estimated total losses at US$155 million.
