If I remember right it was the one that broke its back on a rough
landing. It was filmed and I bet there's a video clip around somewhere.


X-15 #2 suffered a fuselage structure failure on it's third flight, 11/5/59.
It also suffered serious damage three years later when it was landed without
flaps. The high speed caused the left main landing gear to collapse. The
rebuild produced the X-15A-2 version.
