I thoroughly enjoy hearing about your experiences. People today don't realize that trying to fight battles at 30,000 feet was an experiment in physiology and technology-- the human body was not designed for that environment, and you guys stayed up there for hours at a time. As a physician with trauma surgery training, I can't imagine what it was like to be wounded in that environment, with no access to a medic, bleeding and in pain, in the freezing cold, and knowing that it was going to be hours before you could get help. Were any of your crew wounded on your missions?
