Scanners to help with helicopter search
High-tech scanning equipment is to be used in the search for vital components of the Rescue helicopter which crashed off the central Queensland coast on Saturday, killing all people three on board.
Investigators are still trying to locate the rotor transmission and engine which separated from the helicopter on impact.
Air Transport Safety Bureau spokesman Alan Stray says an American investigator with extensive underwater recovery experience has flown to Mackay to assist with the salvage operation.
"Our team has been looking at the currents trying to establish where the floating path or the track of the helicopter from the initial impact so between the Australian expert and the American investigator we do hope to locate those components within the next 24 to 48 hours," Mr Stray said.
The bodies of two of the men have been found and a search is continuing for the third man.
