F-22 pilot vest scrutinized

Published reports say a potentially faulty pressure vest is the latest clue in the mystery over why pilots of F-22 Raptors get dizzy and disoriented. Pilots of the Lockeed Martin-built plane have been told to stop using the vest for routine flights until a fix is worked out. The vest may make it hard for pilots to breath under some circumstances.

The base also trains F-22 pilots. Previous: F-22 mishap probed; Report puts focus on F-22
