Just to expand on this for the uninitiated: LOX storage doesn't just takes up space, its also dangerous.
Maybe its because I am not a racoon trapper (wtf?) but I could not really follow your stream of consciousness post. Here's a couple of thoughts that might answer some of your questions:
1) In the Hornet at least, the green ring to release emergency oxygen is relatively easy to find, unless you fly both high and low lots, in which case it will either be on the inboard or outboard of your left thigh. I try to make a habit of touching (though not actuating) it once a flight, along with the emergency jettison button just for muscle memory. I am guessing its probably in a similar place for the F-22.
2) You could have the emergency O2 automatically actuate with an OBOGS degrade but there are two issues with that. First, that would mean you would have a lot of false positives when someone took their mask off to drink some water or eat a snack and forgot to turn off their flow. Second, it still wouldn't prevent hypoxia events that aren't preceeded by an OBOGS caution, which I think are the most insidious.
3) You can still get hypoxia even with LOX, though its less likely.
4) Ultimately, everything the pilot breathes (LOX, compromised OBOGS, emergency oxygen) shares a common set of plumbing to the mask. So care needs to be taken either through engineering or propper emergency procedures to secure the source of bad air, lest you breathe the good with the bad and still pass out.
Sapper!
Excuse the BS...
My apologies, my response was directed, sort of towards usmarinemike's part about having ejection seats and survival training. Didn't mean for it to come off that lame.
The racoon trap bit is based off of pg 27 of this report http://usaf.aib.law.af.mil/ExecSum2011/F-22A_AK_16 Nov 10.pdf
meaning you shove your hand inside of something, try to grab it and then can't get your damn hand out. I got a feeling you gathered that from telling me where the ring was in your hornet.
I don't belong in the weeds on this stuff as I'm ignorant of it all being a non aviator, thanks for the responses and thoughts.
As usual Recovering LSO hits the nail on the head. I won't claim to know if the F-22 issues are the same or similar to the issues in the VFA community, but there have been known issues for quite some time since it was introduced on the Hornet. To boil it down on the VFA issue there is a molecular sieve that is supposed to let oxygen through and keep out pretty much everything else to yield something like 98% pure O2. That sieve has issues ... sometimes. Again, this is an oversimplification. But the Raptor is very high profile so it gets high profile attention.
The main reason is because LOX is dangerous. LOX leaks can freeze flesh instantly for aircrew in the jet or maintainers handling the equipment. A green apple is essentially a bomb as it is liquified explosives. But as magnet said it also allows for sustained flight or multiple missions without servicing.
Another important issue to remember is that guys are getting hypoxic with their masks ON... That's very insidious and frightening. The reason has to do with sieves (filters) like NVGPen mentioned. If you're flying around with your mask on, and you start to feel funny, you're first instinct might not be to take your mask OFF - though with the amount of visibility and awareness within the A-D/EFG community these days it's probably more likely.
^^ This is going to be good. Nice stash dude.

All I could think of when I watched him talk was this:
I don't know about you, but out of the three, I think he looked most like the gay-bar aficionado...
Ughh, I can't stand reading the comments on that 60 minutes clip.
I'm going to have to vote for Creepy Pedophile if those are the only 3 choices. He's a good dude. I just curious how all of this will go down now.
On a side note, it's time for me to start growing a sweet mustache again. Are those really the only 3 choices I have? I do it mostly because it pisses the misses off.

I think there is also the "peach fuzz is all I can grow because my body is still going through puberty" 'stache.

I say bring back beards.
This is the "I work on an oil rig, and don't care to shave" look.

That is the "I've been on a fucking oilfield boat for a month, and am now on the first of 3 10+ hour layovers to get home" look.
