Some pilots refuse to fly F-22 Raptor amid jet's oxygen problems

Some of the nation's top aviators are refusing to fly the radar-evading F-22 Raptor, a fighter jet with ongoing problems with the oxygen systems that have plagued the fleet for four years.
At the risk of significant reprimand or even discharge from the Air Force fighter pilots are turning down the opportunity to climb into the cockpit of the F-22, the world's most expensive fighter jet.
The Air Force did not reveal how many of its 200 F-22 pilots, who are stationed at seven military bases across the country, declined their assignment orders. But current and former Air Force officials say it's an extremely rare occurrence.

Concern about the safety of the F-22 has grown in recent months as reports about problems with its oxygen systems have offered no clear explanations why pilots are reporting hypoxia-like symptoms in the air. Hypoxia is a condition that can bring on nausea, headaches, fatigue or blackouts when the body is deprived of oxygen.

I can't wait until they try and get the F-35 off the ground and back again without serious damage.
For my money the A-10 as our last worthwhile flight platform.

(6,279 posts)4. The USAF's latest speculation: bad oxygen caused by extreme flight conditions
Since they mainly draw oxygen from cleaned-up compressor air, their best guess now is that maybe the gear that cleans up the oxygen doesn't quite work right under some F-22 flight conditions.
We have some recent data that we are starting to believe, we are coming to closure on that root cause, said Wolfenbarger during a May 8 Senate Armed Services Committee hearing. Were realizing that we operate this aircraft differently than we operate any of our other fighter aircraft, we fly at a higher altitude, we execute maneuvers that are high-G at that high altitude and were on that oxygen system at those high altitudes for periods of time.
Apparently ground crews are also having trouble breathing around the planes... the plot thickens!
