Half of the F-22 Raptor fleet was grounded Oct. 20 after a pilot flying out of a base in Virginia reported a loss of oxygen. But now the stealthy, expensive jets are back in the air, according to Defense Tech.
All this up and down is because pilots keep having “hypoxia-like” symptoms that stem from some oxygen problem—but despite extensive testing, the Air Force has yet to pinpoint the cause.
As Defense Tech put it, “The most troubling part of all this is the fact that the Air Force still doesn’t know what’s behind the reports of possible toxins seeping into pilots’ oxygen supplies on its most advanced jet.”
The Air Force is taking precautions, but “numerous sources had voiced their misgiving about the return-to-flight arrangements,” according to Defense News.
