I saw a Bocke Jungmeister perform this maneuver at an airshow in Mojave, California. I did not realize how old the aircraft was or how long ago the maneuver had been developed. I just held it in memory as I worked later with Phantoms and MIGS. Hammerheads and tail slides were less. Only recently, I have bought and read books about the X-15 and the folks just a little older than I. Streak Eagle and the F-15 was the closest I came to the real thing about altitude and attitude.
