How high do you fly? (what it should have been about)
In light of the "How high do you fly" thread that had nothing to do with what I though it would, and following on from the "What type are you on" thread, how about compiling a list of how high you have piloted an aircraft and what it was in?
Personally I have never been been required to use oxygen, only 9500' in a C172.
I look forward to some unexpected altitudes from light aircraft.
