Thanks for your comment. What you say is safe and true also, what I was getting at is that altitude gives you options ( time to decide) and airspeed bleeds off faster. The faster you are going the faster it bleeds. When you pull a fighter out of afterburner at Mach 2, the jolt is so intense that you are slammed against the shoulder harness. This is obviously the extreme high end. Whether you climb a bonanza at 150 or 100 kt you must learn to unload instantly in an engine failure. You can stall an airplane at any airspeed but you can’t stall at “0” G. I have tested this ancient theory in a T-38, B-52 at Max Gross Weight, and an F111 with double engine failure, and Upside down in an old worn out Taylorcraft (BC12D?) Maybe I was just lucky.
