Sorry to not have your answer.... Read the same article, quite a feat
(somehow I think it rates a different category of record than the space
shuttle IMHO)

Did find some interesting reading though...

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that resulted in it being withdrawn from use.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?
