3 Canadians missing on Antarctic flight

(AP) Three Canadian men are missing in Antarctica after their small plane disappeared.

A search has been launched.

The men went missing late Wednesday on a flight from the South Pole to the Italian base in Terra Nova Bay. An emergency locator transmitter was activated at about 10 p.m. in a mountainous area. But rescue crews have been unable to find the Twin Otter plane.

New Zealand Search and Rescue Mission Coordinator Mike Roberts said in a statement that a Hercules C130 aircraft flew to the Queen Alexandra mountain range but was unable to sight the aircraft, which he presumes has gone down.

He said a joint New Zealand and US field rescue team will attempt to reach the site by helicopter when conditions improve. Weather conditions were poor early Thursday.
