CR, I'm shocked and stunned that you've taken the bait of the two most notorious 'off threaders'. You know, Beagle and ABIW. Such empty lives lead them to seek amusement in this way I feel.
Foz, wade through the deliberate attempts to sway your opinion and look at what you want out of a career.
A summary if you will;
A. Flying, low ethos and a dubious uniform - RAF
B. Some flying in a challenging environment (mainly the challenge to get off the ground) with the inevitable desk job. - AAC
C. A balance of both with hopefully the best bits of both - FAA (Golden rivet inspections a necessity).
The dark horse is a RM commision of course. Take B mix it with C and fill in A.
