FullWings:
That's probably why the drills start with OXYGEN MASKS ON!
and the SLF are told that in the event of a loss of cabin pressure, that: "mask like these (shows mask) will appear from a panel above your head - fit your own mask before helping others"
At a now long gone UK airline, we had a brand spanking newly delivered 757 that had not had the bulk cargo door seal trimmed correctly - twice in a row, it popped out of place leading to a rapid decompression - rubber jungle - fog in cabin - a couple of SLF with bleeding ears - and a full seat cover change!
