As reported by 60 Minutes:
Military officers rarely speak out against their services, but in our lead story you’ll hear from two elite pilots who question the safety of Air Force’s most sophisticated, stealthy, and expensive fighter jet, the F-22 Raptor. Maj. Jeremy Gordon and Capt. Joshua Wilson have chosen to stop flying the F-22 because they say during some flights they and other pilots have experienced oxygen deprivation, disorientation, and worse. They are concerned about their safety in the air, as well as the long-term health consequences. The Air Force says it is doing all it can to investigate and solve the problem, and are keeping the jets in the air with careful supervision of the pilots.
