Having returned from the Falklands recently, there is a very good map on the wall of the Sea-King crewroom, which pinpoints each and every one of the wreck sites on the islands, together with an aircaft ID and dates of crash, including helicopters, herc, mirages, harries etc.
Don't know if the VC10 nav's crash charts still exist on 1312 though. Certainly no sign of them in the det.
