Trim,
I got chopped on JPs ("Nice aeros, but the nearer you get to the ground, the worse you get" was the gist of my chop ride debrief), and I left as soon as possible after being withdrawn from flying training. I didn't think that I could stand being around those that could do what I had always wanted to do since I was a boy. I now regret that hasty decision, as I loved being in the RAF, and was proud to be a commissioned officer. If I have one criticism of that time post-chop, it was that no one made any effort to try and assess if I was really doing the right thing. I think that I could easily have been pursuaded to go nav, or try another branch.
Of course, there's always the possibility that I wasn't deemed to be a great loss to the officer cadre . . . .
