A search is under way in Antarctica for a missing plane with three Canadians on board, New Zealand rescue authorities said on Thursday.
An emergency locator beacon from a Twin Otter plane flying from the South Pole to the Italian base in Terra Nova was activated late on Wednesday in the northern end of the Queen Alexandra Range.
A search by a U.S. National Guard Hercules failed to spot the plane, and a second flight over the area was planned, the NZ Rescue Coordination Centre said.
Weather conditions in the area were said to be poor, with low cloud and strengthening winds.
A joint New Zealand-United States field rescue team was assembled and a helicopter was due to drop them into the area when conditions improved.
