Pentagon restricts F-22 flights, safety a concern
By ROBERT BURNS | Associated Press – Wed, May 16, 2012
WASHINGTON (AP) — Facing a mysterious safety problem with the Air Force's most-prized stealth fighter, Defense Secretary Leon Panetta on Tuesday ordered new flight restrictions on the F-22 and summoned help from Navy and NASA experts. Panetta endorsed Air Force efforts to figure out why some F-22 pilots have experienced dizziness and other symptoms of an oxygen shortage while flying, but his personal intervention signaled a new urgency. A secretary of defense does not normally get involved in a service-specific safety issue unless it is of great concern. The Air Force grounded its F-22s for four months last year because of the oxygen-deficit problem, and now some pilots are refusing to fly them.
