High level ! Are you serious? Even on the Vampire T11 we started. WAY. higher than that, went over the top at around 35 K, under partial control !! I doubt we started or even finished at .8 Mach though.
That said, the only underwear involvement was a change on landing after a nasty fright, recovering from a high level loop !
The only booms on the Vampire supported the tailplane !
