Aaron, BEagle is not THAT old
The exercise would have been Moonflower to the Far East. IIRC the whole Cottesmore Wing was put on notice - 24 ac - and all flying ceased as ac were prepared. After 8-10 days reduced essential training was recommenced then, possibly on a Tuesday, we were ordered to send 16 ac or 2 sqns. As 12(B) had done the first Det in 1964 we were the stay behind sqn and had to cover all 3 QRA ALN.
I don't recognise Don Arnott in that picture but the one with th eplaque at his feet could be just possibly be Mr Pastry if he has scrambled egg on his hat.
