I was told be a somewhat mad engineering lecturer that at Concorde cruising levels, a depressurisation will drop the cabin pressure to the point where water will boil at body temperature. (i.e. you will start to boil)
He then went on to assure us that the O2 gear was therefore useless at this altitude.
Is there any truth to this?
Thanks in advance, Dave.
