The remains of the plane's fuselage had not been visible since the 1970s
A team of Australian conservationists say they have found what they believe to be the remains of the first aeroplane ever taken to Antarctica.
Australian explorer Douglas Mawson had the single-propeller Vickers with him on a 1911-12 expedition but it was abandoned because of engine troubles.
Brought to the frozen continent without its wings, the plane was used for a time as a kind of motorised sledge.
The conservationists are working to restore Mawson's original wooden huts.
The plane had not been seen since the mid-1970s, when researchers photographed the steel fuselage nearly encompassed in ice.

After searching for three summers, the Mawson's Huts Foundation team stumbled upon metal pieces of it on New Year's Day.
"The biggest news of the day is that we've found the air tractor, or at least parts of it!" team member Tony Stewart wrote on the team's blog from Cape Denison in Antarctica's Commonwealth Bay.
The "air tractor", as the plane was described, was abandoned by Mawson's expedition because its engine could not withstand the extreme temperatures. The engine itself was removed and returned to Vickers in the UK.
Mawson had removed the plane's wings back in Australia because of an accident during a demonstration flight in Adelaide which had damaged them.
Nobody was hurt in the accident but there was no time for repairs before the 31-strong expedition set sail for Antarctica.
"The pilot was sent home to England in disgrace while the fuselage was used as an air tractor to tow sledges," according to the Mawson's Huts Foundation website.
Mr Stewart said it had been an "exciting search".
"Friday was possibly the only day in several years when the rocks were sufficiently exposed and the tide was low enough and we were here to see it," he added.
