Yes it is.
Whilst chasing some Jaguars at low level on an exercise years ago, I suddenly noted a twitch on the pressure altimeter. "Transonic Jump", thought I and throttled back immediately whilst muttering "DON'T PULL" to myself.
Probably knocked the osprey off its nest - sorry!
When the Hawk first appeared over Wales, it seems that selecting airbrake at high IMN would pop a boom - there had been a few unexplained Viet Taff complaints.
