These discussions of the X-20 and other rocket launched gliders reminds me of this bit of trivia: Q: What was the first winged vehicle to fly faster than sound, and when did it fly? If you say the X-1, you're wrong. The X-1 was the first *manned* winged vehicle to fly faster than sound. The first unmanned vehicle was a glider launched by the Germans on a V-2 in January 1945. It glided at Mach 4. -------
