Oxygen System Didn’t Cause F-22 Crash

This is interesting. The crash of an F-22 Raptor out of Elmendorf Air Force Base in Alaska late last year was not caused by problems associated with the plane’s oxygen system,  Air Force Chief of Staff, Gen. Norton Schwartz told Air Force Magazine yesterday.

The onset of summer in Alaska allowed investigators to get their hands on  “hardware and computer memory that made a more comprehensive analysis possible,” wrote John Tirpak of Air Force Magazine. This analysis apparently led the investigators to decide that problems with the oxygen system didn’t cause the crash. The investigation had been delayed by harsh winter weather that kept investigators from recovering all the evidence from the crash site.

The service began investigating the Raptors’ on-board-oxygen-generating-system after the fatal crash in late November 2010. The investigation has been looking at whether carbon monoxide and other toxins are seeping into the system, called OBOGS, that provides pilots with air to breath at high-altitudes. 14 Raptor pilots at six bases around the United States have reportedly experienced hypoxia-like symptoms after using the OBOGS system.

Suspected problems with the oxygen system  famously led to the grounding of the entire F-22 fleet in early May — a grounding that remains in effect. (Schwartz also told AF Mag that the F-22s will be flying soon and that the Raptors’ flight to flee Hurricane Irene last weekend was the start of a phased plan to get them back in the air.)

    So what are other possible causes of the AK crash?

  • Chops

    I wonder how much Lockheed Martin is getting charged for each day the Raptor is grounded because of a manufacturing defect.I thought I saw somewhere that w/ the 155 F22s in the current fleet the cost of each bird is @450mil.–that’s quite a bit for a plane that can’t fly without making the pilots sick.These defense contractors are getting away with fleecing the military and taxpayers and not one of our paid-off politicians is doing a single thing to stop it.

      ADD—This is at least a 30yr. life span plane–at 450mil. per copy that translates to $41,095 per plane per day value.That makes the cost of the 150 plane fleet at $6,164,384 per day for something that can’t fly.

      Um don’t you think that they could just upload an auto pilot and turn these into UAVs?

  • Lance

    Why dont they just use the F-15s oxygen system and fix it so F-22s can fly again.

    • Cheesed

      I could certainly be wrong, but my guess is that they won’t because “the crash … was not caused by problems associated with the [F-22]’s oxygen system.”

      • Chops

        Supposedely–but consider that F22 pilots have been tested and toxins have been found in their blood system.They don’t have any answer for this either but it seems this condition is only showing up in F22 pilots.If they would spend as much time worrying about the plane and pilots as they spend worrying about Lockheed Martins reputation and profit margin the plane would be in the air again.

      It not like dropping a transmission in a FORD…………. Not that simple.

    This whole episode with the grounding of our F-22’s all of a sudden reminds me of the premise of the movie “Apollo 18” & why we haven’t returned to the moon. I’m very sure that the Air Force knows exactly why the F-22 crashed. I’m also sure they don’t want us to know or it will cause a panic. I half heartedly joked about it earlier with my “HAARP” explanation. I bet it was the same thing that caused the crash of that B-2 bomber in Guam years ago(& you could probably include the Challenger Space Shuttle in that),& no,I DON’T believe space aliens or UFO’s were involved,nor do I believe it was a “Fringe(as in the TV show Fringe)” event. Russia & China aren’t exactly the Dilbert nation of “Elbonia.”

      “I’m also sure they don’t want us to know or it will cause a panic.”

      Good for you. Now the actual evidence for that statement is where?

      “I bet it was the same thing that caused the crash of that B-2 bomber in Guam years ago(& you could probably include the Challenger Space Shuttle in that)”

      Unless you can provide som hard evidence to back that up, you’d lose that bet.

      I guess that anytime something goes wrong with an incredibly complicated US machine, it must be because of the sinister machinations of Dr Fu Manchu. Working in commie collusion with Boris Badenuv and Natasha, of course…

      • Thomas L. Nielsen

        Don’t forget MAJIC12, the Bilderberg Group, the Zionist Conspiracy and Bigfoot (especially Bigfoot – he’s sneaky for such a big, hairy guy).

          No,it was global warming.

      • barts dad

        or maybe just that the pilots have been starting and warming up the aircraft indoors in hangers. dohhhh!

  • Roland

    Its possible The oxygen become unusable because of cold temperature.

  • Roland

    The F-22 jet probably needed some insulaition on it’s frame and check and double check the oxygen system design and the problems of F-22.
