Bob was killed in an Islander in January '84 near Omkalai (it was either ISG or ISH, I can't recall which).
It was not his girlfriend that walked into the propellor, but was Kerrie Foley, sister of one of Bob's good mates (Chris Foley, also now deceased), who was sitting in the RHS of the Islander when the accident occurred at Hagen. 20th July 1980, P2-ISF.
Tragedy was that they were about to launch and participate in the search for another Talair aircraft, Baron P2-GKN, which had pranged in the Tari Gap the previous day with the loss of all on board.
