I agree with Whowhenwhy - Bra's motivation for joining the RAF isn't exactly strong.
He did, however, say he was "an action/energy thirsty chap". You don't see many of those sitting around LACC bitching about whether they're 'mobile grades' or not!
(Having listened to some of the BS about military ATC that comes out of some instructors/students mouths at Hurn, I think only people that have done both are able to compare the two fairly!)
