The wreckage of a Twin Otter aircraft missing in Antarctica since Wednesday night has been found and the three-member Canadian crew is believed to be dead.
Officials with the Rescue Coordination Centre in New Zealand say a helicopter spotted the wreckage on a steep slope near the summit of Mount Elizabeth.
They say the impact appears to have been direct and would not have been survivable.
The next of kin of the three men have been informed.
Mission coordinator Tracy Brickles says it was very sad end to the operation.
