Oct. 25 (Bloomberg) -- U.S. Air Force F-22 fighters have resumed flight operations at Joint Base Langley-Eustis in Virginia, after a suspension due to continued concerns about possible pilot oxygen deprivation.
Flights by Lockheed Martin Corp.’s F-22 Raptors resumed this morning, Miles Brown, an Air Force spokesman at the base, said in an e-mail, without providing any further details.
An Oct. 20 “physiological event” prompted a suspension of F-22 flights at Langley, spokeswoman Monica Miller Rodgers said yesterday. Langley has about 30 F-22 fighters.
The brief suspension came one month after the Air Force lifted an F-22 flight ban imposed on May 3 as a precaution after 12 incidents in which pilots experienced “hypoxia-like symptoms” associated with lack of oxygen, according to a statement from Air Combat Command. Oxygen deprivation might lead to disorientation or blackouts.
The stealth F-22 jet first entered service in 2005. The Air Force has fielded 170 of the planes as of May.
