I remember seeing the aftermath of the hypersonic flight on one of the
cable channels (History? Discovery Wings?) but haven't yet found the site.
IIRC, the damage that grounded X-15 #2 was from the thermal environment.
I
have a mental picture of the rear of the aircraft (horizontal stab, skin
near the engine bell) burned through. Will keep looking.
