Has anyone looked into what might be leaching into the cockpit itself during flight? With all that equipment, seems there'd be a lot of exotic material getting heated up, possibly getting vaporized into the air outside the mask. If a guy goes to scratch his nose or something, he might inhale something he shouldn't, something that might interact with the stresses of high g-load or something else. How is cockpit temperature maintained anyways? It might explain why the problem seems worse in Alaska. Perhaps a heating element of some kind is having to burn hotter or longer than usual in the colder climate. Has anyone ever noticed how heaters sometimes give off fumes when they're turned up all the way?


I'd personally look into what would be producing natural gas in flight. That just sounds too odd.

I find it interesting AF has installed activated carbon filters for the pilots. Resolution might be a lot cheaper if OBOGS isn't the source but I might be concerned about longterm effects on the pilots' health.


They did that? that was my "advice" during the first grounding hah.

What worrisome is that this situation could bring mental pressure on the pilots and affect their confidence.

I would have thought that an issue affecting life support systems would be top of the agenda to isolate and fix?? There must be some obscure combination of factors that they simply haven't considered yet.

I would have though the actual oxygen generating system would be pretty robust/reliable as it is hardly a new concept, and the Shuttle for example has been flying with them for decades, AFAIK without problems.

Similar technology but different design and execution. F-22 OBOGS was tailor made for the platform. I believe it represents the first implementation where the matrices into which are bound the metal that actually interacts with and slows down the nitrogen passing through are produced from plastic instead of mineral. It's possible that atmospheric contaminants in certain places, conditions and times are gumming up the works and the labs did not test with them. I dunno but then I am not alone in my ignorance unfortunately.
