As the Air Force searches desperately for the source of a mysterious and potentially deadly oxygen system problem in its $79 billion fleet of F-22 Raptor fighter jets, it is also investigating why the jets’ pilots are coughing so often after missions that the pilots have taken to calling it the “Raptor cough.”

For decades pilots in fighter jets have been contending with temporary fits of coughing after executing extreme maneuvers in the air, due to a known condition called acceleration atelectasis, but an Air Force spokesperson told ABC News that the coughing appears to be more prevalent in F-22 pilots.

And while the current thinking by the Air Force is that the F-22 pilots suffer more bouts of coughing than their counterparts is because the F-22 can fly at more extreme speeds and altitudes, Air Force spokesperson Lt. Col. Tadd Sholtis told ABC News that the service has not discounted the possibility that toxins that may have leaked in to the oxygen system could be exacerbating the coughing.

The leakage of toxins into the oxygen system is also a possible cause of F-22 pilots experiencing dangerous “hypoxia-like symptoms” while flying the Raptor in more than two dozen cases since 2008, as reported in a recent ABC News’ “Nightline” investigation. Hypoxia is caused by a lack of oxygen to the brain and is characterized by dizziness, disorientation, poor judgment and, eventually, unconsciousness.

Last year the Air Force grounded the full fleet of F-22s, which cost U.S. taxpayers more than an estimated $420 million each, for nearly five months to investigate what was causing the incidents, but never could come up with an answer and sent the planes back in the air.

Over the weekend, one of two F-22 pilots who spoke out publicly to CBS News’ “60 Minutes” about their fears of flying the F-22 linked the “Raptor cough” with other symptoms associated with the “hypoxia-like” incidents, saying that in a room full of F-22 pilots, “the vast majority will be coughing a lot of the time.”

Sholtis said that there are no hard numbers on how many F-22 pilots are experiencing the “Raptor cough,” but said it’s obviously “common enough to have developed its own moniker.”

Last week the Air Force officially received the last F-22 Raptor from defense contracting giant Lockheed Martin, completing an order of 187 planes that cost U.S. taxpayers an estimated $79 billion — meaning that including research, development and production among other costs, each plane has a price tag of more than $420 million. Despite being the most advanced fighters on the planet, none of the planes have been used on a combat mission since they went combat-ready in late 2005.
