As part of its investigation into the cause of hypoxia-like symptoms affecting a few F-22 Raptor pilots, Air Combat Command this week released new conditions regarding what pilots can wear while flying the aircraft. Testing has apparently found problems with the pressure vests worn by F-22 pilots as the upper portion of their G-suits. Air Combat Command spokesman Lieutenant Colonel Edward Sholtis told Bloomberg News that the vest is "like a tight-fitting garment" and that it was not properly fitted for pilots, possibly restricting their ability to breathe. But finding a fix for the vest is not expected to resolve the hypoxia-symptom issue.
