Warping flight. Is...

Blackbird books (was: hi-speed ejections) by
Paul A. Suhler

"Lockheed's SR-71 'Blackbird' Family: A-12, F-12, M-21,
D-21, SR-71" by Jim Goodall and Jay Miller.

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
