Ground crews have also reported growing sick while working around F-22s whose engines are running.
The Air Force claims its has a handle on the in-flight blackouts.
has some bad news for the pilots of its F-22 Raptor stealth fighters: Your planes are going to make you feel crappy and there's not much anyone can do about it.
And the message to the maintainers of the radar-evading jet is even depressing.

They think that while we are away that we are on vacation and partying.
All 180 or so F-22s are having faulty filters removed and new backup oxygen generators installed.
The shots of them in combat ring about as true as Spy Kids.
But the Air Force says the alterations won't do to fix the so-called "Raptor cough," a chronic condition afflicting almost all F-22 pilots.
The coughing – which, to be clear, is a totally separate issue from hypoxia – is due to a condition known as "acceleration atelectasis," Maj. Charles Lyon, who headed the Air Force's Raptor investigation, wrote in response to questions submitted following a September testimony before a House subcommittee.
Any illness they feel from working around the Raptor is apparently all in their heads, according to the Air Force.
Those admissions, buried in newly released Congressional records, represent the latest twist in the years-long saga of the F-22's faulty oxygen system, which since at least 2008 has been choking pilots, leading to confusion, memory loss and blackouts – combined known as hypoxia – that may have contributed to at least one fatal crash.
Everyone wants to make a good impression on a first date, but for Caroline Scholes and David Eshelman, the stakes were a little higher.
