I'm still trying to figure out the oxygen in cabin fire hazard part...
if they only went over to suit oxygen when they first started to
interface with the atmosphere and back to cabin air once they had
decelerated to under, say, Mach 2...then one wouldn't think there would
be enough time for a excessive oxygen situation to develop, as this all
takes under half an hour.
