Air Force to decide Monday whether Arizona F-35s will fly again after oxygen problems

The Air Force is set to make a decision Monday on whether F-35s at Luke Air Force Base in Arizona will return to the sky, said Brig. Gen. Brook Leonard, 56th Fighter Wing commander.

Leonard said the service is looking at altitude restrictions and safety measures that will allow the aircraft to fly, but still has not pinpointed why five F-35 pilots at the base reported oxygen deprivation incidents over the past five weeks. One of the affected pilots belongs to a visiting foreign military.
