X-15 damage

From: "Paul F Austin"


In Pete Knight's obituary in AvWeek, it mentioned that the record setting
Mach 6+ flight in the X-15A2 resulted in structural damage to the aircraft
that resulted in it being withdrawn from use. Was the damage a result of the
thermal environment or was it the dynamic pressure envirnoment?

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.
