Audio of an F-22 Pilot Getting Hypoxia

That’s right, someone recorded an F-22 Raptor pilot using the callsign Rocket 04 declaring an emergency after suffering hypocia-like symptoms while flying in the famous Red Flag combat excercises at Nellis Air Force Base in Nevada earlier this year.

Listen to the tape to hear Rocket 04 report his situation and request an immediate descent to 18,000 feet so that he can breather easier and asses his situation. Rocket 04 left the battlespace and was escorted home by another F-22, Rocket 03.

As David Cenciotti points out, this pilot was likely from the 27th Fighter Squadron, a unit of the Langley AFB-based 1st Fighter Wing, the same wing that those Air Guard pilots who refused the Raptor belong to. Those Virginia guardsmen refused to fly the jet due to concerns about Raptor pilots suffering from hypoxia-like symptoms with alarming frequency.

    I'm curious to know if any intense maneuvers were performed prior to the symptoms arising. I can't hear the audio since I have no speakers on this computer unfortunately. I don't think the OBOGs is providing enough air to the pilot. It could be a similar computer glitch with the bleed air system affecting life support just like Haney's bird. If that's the case, the software needs to be updated to prevent the computer from automatically disabling OBOGS, but allow the pilot to manually disable it and activate the emergency O2 system (via the new lever).

    However, if it's contaminants infiltrating the OBOGs, rip the system out and replace it with LOx. Whatever is used on this plane to make it more stealthy (fuel, coatings, etc) may be gassing out and into the Bleed-Air/OBOGS.

    Clearly it's pilot error!

    This does not help me understand anything. I'm moving on.

  4. It kind of makes you wonder if it's a virus attack not unlike that against Iran's nuke program.

    I’m curious if LM used the same OBOGS gear in the F-35, but the hypoxia issue just hasn’t yet come to light there because there aren’t enough F-35s out there to start any serious air combat maneuver training and discover their OBOGS (or whatever) doesn’t work right, either.

  6. Makes me wounder why Lockheed installed such a crappy Oxygen system? Too keep cost down? Time to bring back the F-15 for now.

  7. Is it really so difficult to just give these men and women spare airtanks they where on their flightsuit. If they start having breathing issues put on the spare till you find the secondary in the cockpit. And that can work till you fix it damnit.

    Perhaps they already found the solution, but they aren't saying it.. Maybe our enemies have copied the technology, but are facing the same problems until a solution is spilled. You never know…

  9. Let’s become friends with Russia to destroy China!

    its the engines…. i base that on absolutely nothing.

    We need to take these jets completely apart till we know what's up. Until then our air superiority will be done with our reliable 4th gen and 4.5 gen fighters. All of our malfunctioning fighters seem to come from Lockheed. They need to get their crap together.

  12. Air goes in, air comes out; and there’s a finite number of bits and bobs in between. How hard can it be to find the problem?

  13. Hope someone from the air force reads these blogs for ideas. I am still rooting for low pressure around the engine air intakes due to more powerfull engines causing hypoxia of pilots and ground crews. The engine intakes are only a foot or two from the pilot.

  14. Solve the oxygen system problem of F-22 and reuse it after the fixes. We still need the F-22 for defense. But it needed to fix the oxygen systems in F-22.

  15. am i the only one wondering how someone managed to record it?

  16. If he is having hypoxia symptoms why isn't he asking to descend to below 10K where he does not need the onboard oxygen system? At 18K he's still dependent on the system which is supposedly causing him his problem. This just doesn't make a lot of sense.

  17. Test for infrasound induced hypoxia symptoms. New theory.

  18. I was told the same oxygen system is used on the Navy's F/A-18. If true, why isn't it happening in those aicraft?

    I couldn't "filter" through the controller/pilot jargon. that which sounded like routine flight conversation didn't appear to me (who am I?) that Rocket 04 was in any kind of distress. it's going to take an expert, e.g., test pilot or flight surgeon, to determine if he was actually experiencing Hypoxia. This is WAY outta my pay grade!

    This is a typical govt lack of common sense. When u don't get oxygen, u pass out and die peacefully. Put a team to troubleshooters together, including one common sense leader, preferably outside the military's control. Preferably someone with no technical knowledge who will ask the stupid questions …. Like why is that hose wrapped around something that reacts to changes in altititude and looks like it is part of the oxygen delivery system? Do not let them leave until it is fixed. Tell the big egos to stay home.

  21. Either fix the oxygen system or start producing robo pilots to fly and land the F-22.

  22. Most fighters have two radios. Throughout most of the flight usually one radio is used for mainly for interflight communications. Rocket 1,2,3 and 4 would have their own interflight frequency. The other radio would be tunned to whoever is controlling the flight. It is on this control frequency that we hear one of the Rockets inform the controller of Rocket 4's problem. Rocket 4 is not heard and was probably just talking on the F-22 flight interflight radio. For all we know, it was just a case of food poisoning. Nausea is one of the hypoxia symptoms. Or it could have be the real thing and very serious. Without hearing Rocket 4 himself there is no way for us to tell.

  23. Wow’ many comments. IMHO US military and defense industry are simply stumped. Nowadays, it takes global effort on any project as technically demanding as the F-22. The US no longer has a monopoly on such projects, if it ever did in the past. We don’t educate enough US engineers of almost all engineering disciplines and must rely on new immigrants to the USA and other nations for high tech work That should not mean we allow a bunch of out-and-out spies to all over us.

  24. My glaring concern is that the problem caused 2 fighters to leave the battlespace. Might as well have been lost to enemy fighters or engine failure. 2 of our best assets had to RTB because of… what? Bad engineering? Lack of leadership and determination by the AF brass?

    2 less assets of this caliber affects the mission plan greatly and could even be a deciding factor in some battle or even war.

    Why would the AF not want to fix this problem immediately considering the weakened posture of the rest of the flight/mission and overall force?

    Its almost as if the USAF has sworn this plane off and could care less about the world's front line fighter. This is stupid and petty because if a Republican gets back into office I think the F-22 lines will stay open and hopefully the program can start looking at future upgrades… and I think Gates knew this.

    The F22 is a better machine than the F35 all day every day. When I think of the problems with the F22 I get a sick feeling in my stomach about the future with 2000 F35 (inferior) built with the same OBOGS and by the same company… who knows what else is going to come out in the future. Its terrifying.

    so this is the reason why they rolled off the production of f-22?
    The final F-22 Raptor rolled off the production line last December 13th. http://airsoc.com/articles/view/id/4fac5770c6f8fa
