There was a daily (M-F) trooping flight from Luton to I guess Hannover (brain cells dimmed by cheap wine), flown by Britannia I think.
One of my ushers was booked on said flight ex Luton.
On check-in at the Britannia/Movements desk he was told he had a prisoner (19 y/o who'd gone AWOL from his unit) to escort back to the Fatherland.
Bob drew himself up to his 6'3" and said in his best voice (he was an actor in his day job). "We don't take prisoners in this regiment". The face of the Cpl on the desk was quite something.
