Luke F-35s grounded

The Air Force has temporarily grounded a squadron of F-35s at Luke Air Force Base, Ariz., after five pilots reported symptoms consistent with oxygen deprivation, the service said Friday. The 56th Fighter Wing canceled local flying operations for its F-35A fighters after five incidents since May 2 where pilots experienced symptoms similar to hypoxia, or oxygen deprivation. Each time the F-35's back-up oxygen system kicked in and pilots were able to land the plane. Flight operations are scheduled to return Monday. F-35 operations at five other bases are not affected.
