I know most of us don't like to go idle power and point the nose down looking for VNE. Like other emergencies, we need to be mentally prepared when the need arrises. I did it once when an O2 tube came off at a connection when at 19,000 ft. In about two breaths I felt pretty loopy. I tried to reconnect the tube and found myself fumbling with it. Then I did the screaming dive. It takes a LOT longer to loose 10,000+ ft than you might think. An emergency O2 bottle becomes a good idea at higher altitudes. In the Air Force, we carried a small tank as part of the chute when operating above 25,000 ft. Mark Ravinski N360KB 1390 hrs
