Pentagon: Blame Tight Vests, Not Stealth Jets, for Choking Pilots | Danger Room | Wired.com

The mysterious engineering problem causing F-22 Raptor pilots to choke in their cockpits has been solved, the Pentagon says. And it’s not the nearly $400 million aircraft’s fault after all.

The problem lies with a valve in the pressurized vest pilots wear as they fly the jet at high altitudes, Pentagon spokesman George Little said. The valve inflated the vest, limiting the pilots’ oxygen supply. It does not appear that the vest was affecting quality of the oxygen in the Raptor. The valve will be replaced; the garment’s use will be “suspended,” Little said.
