Well, it arrived. Very thorough. It even includes photocopies of letters my mother sent from Australia when I was fifteen, asking about qualifications needed etc.
What show up though are how subjective the various reports can be, and how much pressure must have been on superiors to produce something. My reports vary from "excellent, keen, proactive, good flying ability" to "uninteresting, no leadership ability, barely average pilot"
I think I'll keep them, particularly my mother's letters, but they aren't going to affect my life. I left just after my 30th birthday, and I'm 70 now, so water not just under the bridge, but several water-cycles gone.
