I wonder how they define "useful" consciousness...  I have
heard that one would stay conscious for thirty seconds or so
in a total vacuum, but I don't know how "useful" it would be.

Given that they almost certainly lost consciousness, the next
morbid question is whether they regained it once they got below
12,000 feet or so...  I wonder why people want to know such
things.
