I bet you can now sleep at night having got that off your chest. I take it you think that during the Falklands there were only 20 Movers at ASI and nobody else. Considering the real estate at ASI I would guess there wasn't much space for anything, where would mail have been kept? Once it left ASI assuming by air, I take it any bored passenger sat on the Herc would not have been tempted to have a fiddle with the freight, or did your mates have a rummage before delivering it to you. I might have to ask a few of my mates who are still serving and where in ASI at the time.
Anyway enjoy the next 27 years until the next oppertunity arises for you to vent your anger.
