F-35 grounding at Arizona base extended indefinitely amid hypoxia probe

‘The decision to ground all F-35 fighters at the Luke Air Force Base in Arizona was extended indefinitely, as special teams of experts struggled to figure out what caused multiple incidents of pilots reporting oxygen deprivation.
Brigadier General Brook Leonard, commander of the 56th Fighter Wing at Luke, suspended flight operations on Friday after reports of five “physiological incidents” since May 2. Flights were supposed to resume. Monday, but the ground stop remained in place.
“The 56th Fighter Wing will continue their pause in local F-35A flying to coordinate analysis and communication between pilots, maintainers, medical professionals and a team of military and industry experts,” base spokeswoman Major Rebecca Heyse said in a statement. “This coordination will include technical analysis of the physiological incidents to date and discussions on possible risk mitigation options to enable a return to flying operations.”’
