Altitude set once or more than once?
I have read all the posts before posting. I wish others did. I have not seen a resolution to whether the altitude set was made one time only, just before the beginning of descent, or whether there were subsequent resets, as has also been posted. This makes a big difference on the question of consciousness. The noise of breathing, without characterizing any changes in it, is by itself no proof of consciousness. If unconscious, knocking on the door, and musings about what one moral issues one thinks about during an 8 minute suicide, are moot confusions.
