The U.S. Air Force has grounded all F-35 flights out of an Arizona base after a series of incidents in which pilots reported suffering oxygen deprivation symptoms while in the air. “The Air Force takes these physiological incidents seriously,” a high-ranking U.S. Air Force commander stated.

The U.S. Air Force decided on Friday to ground all F-35 flights out of the 56th Fighter Wing at Luke Air Force Base in Arizona after several pilots reported problems in their air supply system. This appears to be the first significant problem discovered with the advanced aircraft. The suspension is expected to be lifted by Saturday.

“In order to synchronize operations and maintenance efforts toward safe flying operations, we have canceled local F-35A flying,” said Brig. Gen. Brook Leonard, a senior U.S. Air Force commander. “The Air Force takes these physiological incidents seriously, and our focus is on the safety and well-being of our pilots. We are taking the necessary steps to find the root cause of these incidents.”
