Mawson's Hut aircraft
For info, the seat of Mawson's aircraft was found and identified last summer - I have some pics of it. The ice coverage/melt changes a little each year and the seat was exposed amongst some rocks at Boat Harbour where people land for Mawson's Hut. Capt John Dennis of Qantas overflights was also on the ground there when the seat was found. The probability is that the rest of the aircraft has been carried into the sea by the wind and ice movement - but good luck to the search.
