Don't know about the others, but I am sure that Ian Monkhouse went on to join the CAA SRG as an examiner and then do other ATS Investigation stuff with them.
Another name to conjur with: Al Bailey, a brilliant instructor who, during his days off from Bailbrook Asylum, went flying as a F.O with DanAir.
He then went on to join SRG as well.
On my approach course he turned up to do the CAA bit.
Sitting in the exam room for the writtens we were all told we could start, only to find that he'd slipped in photo's of each of us on the group piss up from a few days back.
A great bloke.
