An investigation has been launched into a plane crash that killed three Canadians in Antarctica.
The men were killed when the Twin Otter plane they were in slammed into the Queen Alexandra mountain range en route to Terra Nova Bay in January.
The Transportation Safety Board (TSB) of Canada will conduct a full independent investigation into the crash in case of significant safety findings.
"Everything we know at this stage points to a controlled flight into terrain (CFIT) accident, which is an issue on the TSB's watchlist," said Director of Air Investigations Mark Clitsome.
The New Zealand Transport Accident Investigation Commission has been assisting the TSB since the crash.
The three men killed, Bob Heath, Mike Denton and Perry Andersen, were farewelled at an informal memorial at the South Pole a week after the crash.
