Glenforsa was (and probably still is) a regular drinking hole for certain university diving clubs. On one occasion in the 1980s the barman promised to buy us all a drink if I identified all the a/c models hanging from the ceiling. I did, but then couldn't find him
We dived the remains of Peter Gibbs' Cessna in October 1986 and found a wing in 32m. We carried out a search from the wing to see if any other wreckage lay nearby, using compass bearings, but found nothing. Proved the compass by swimming back to the wing, and picked up plenty of scallops, which made a good lunch.
I remember watching some impressive aerobatics by model a/c too.
Never flown in there, but one day...
