My info from a well known ex DCA editor of the crash comics that there have been several RFDS/Aerial Ambulance accidents. They are:
RFDS Baron in Tasmania 1979.Pilot J. Lingridge. Heard to take off from Devonport for Wynyard at night. Crashed into hills. Suspect heart attack - incapacitation.
22/10/53..DH84 Cheviot Hills to Charters Towers. Too heavy, hot day, failed to climb..killed two.
4/2/56. Anson on charter from MMA to RFDS. Ran into thunderstorms at night en-route Derby. Killed 5.
More recently in England. Aerial Ambulance Navajo single pilot. Non-precision VOR/DME runway 09 approach into Liverpool in 2000 metres and low cloud. Highly experienced GA pilot. Hit one mile short and killed 3.
Interesting to note that Police Air Wing operate helicopters with one pilot and observer in other seat up front on aero medical ops. ie Two crew.
