The wreckage of a Twin Otter aircraft that was reported missing earlier this week in Antarctica has been found in a remote and mountainous area of the continent.
An initial assessment by Kenn Borek Air Ltd. of Calgary, Canada, the owner of the plane, deemed the crash "not survivable."
Weather has prevented search-and-rescue personnel from landing at the site.
The National Science Foundation (NSF), as manager of the U.S. Antarctic Program (USAP), has been cooperating with the Rescue Coordination Centre in Wellington, New Zealand, since the search-and-rescue effort to locate the missing aircraft--a de Havilland DHC-6 Twin Otter--began earlier this week.
Communication with the Twin Otter was lost on Wednesday night, New Zealand time, and search-and-rescue operations have been hampered by bad weather and poor visibility since that time.
The plane was flying in support of the Italian Antarctic Program under the logistical responsibility of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development (ENEA). The aircraft was enroute from NSF's Amundsen-Scott South Pole Station to the Italian research station at Terra Nova Bay when contact was lost.
The three crew members were the only people aboard the plane at the time.
On the afternoon of Saturday, Jan. 26, local time, a ski-equipped LC-130 aircraft--operated by the New York Air National Guard for the USAP and flying from NSF's McMurdo Station--overflew the last known position from the aircraft emergency beacon and spotted the aircraft tail at an elevation of about 3,900 meters (13,000 feet) on Mt. Elizabeth, a 4,480-meter (14,500-foot) summit in the Queen Alexandra Range of the Transantarctic Mountains.
Subsequently, a Twin Otter carrying U.S. and New Zealand search-and-rescue personnel conducted an aerial survey of the site and determined that a landing by fixed-wing aircraft was not possible.
Later, two helicopters--one under New Zealand charter and the other flown for the USAP by PHI, Inc. of Lafayette, Louisiana--arrived at a small camp established roughly 50 kilometers (31 miles) from the crash location to support the operation.
The rescue teams will attempt to reach the site, if conditions permit, before returning to McMurdo Station.
