Great photos DB, brought back many memories.
I was in Malta from 1972 -1974 with 41 Commando Group, Royal Marines. We were based in St George's Barracks with our Sioux AH Mk 1's and spent many a happy hour either training or taking people on the Cook's tour around the islands.
BTW, The diving is - or rather, should I say, was, excellent on Gozo. Xlendi was particularly good with the remnants of the Roman fleet and the whole amphora sitting in the sand. Every time we returned to harbour, a local Policeman would inspect our boat to make sure we hadn't lifted any artefacts.
Is the Spitfire still in the small bay on the north side of Gozo? Only in about 30ft, or should I say 10 metres. The Roman stuff was at about 35 metres, if my memory serves me well.
