One thing that I found amazing was the F-15 lifted off from a dead stop in 400 feet, or a little over 7 plane lengths! If you noticed they had it fastened to the runway until the pilot got both burners lit, and up to full thrust. There is no way the brakes could hold it with the thrust to weight ratio it has. And the thing to remember is this is 38 year old technology, and to this day nothing can out climb it! Bill T.
