The shot at 3.42 looks like Observation Hill at McMurdo Station on Ross island, Antarctica. Named by Scott. I have climbed this for the inspirational view many times whilst I worked at Scott Base, the NZ Base. This is where the TAE finished the crossing of Antarctica. Sir Ed (Edmund Hillary, 1st summiter of Mt Everest) set out the depots of fuel for Bunny Fuchs and the TAE and then decided to carry on to the South Pole. He used tiny English Ferguson tractors modified with tracks..
I was at the Tucker factory in 1977 and they had one of the machines from this expedition in a shed. The Brits left the others there but brought one back and gave it back to Tucker. Tons of wear on it - tough trip.
There is one of these Trans Antarctica Expedition Tuckers at the Christchurch Museum, New Zealand. I looked at it often as a kid, so it is nice to see them in action with the tracks pivoting.
Nice recovery! I wonder if that was something they had figured out how to do beforehand, or if it was just an example of ingenuity at work? I'm guessing a bit of both...they did have those long traction planks, but I'm thinking they were intended for less extreme circumstances.
Nowadays it is said in the info: Forgotten Ambition from Musicshake (or Renerade)... I have been searching this for ten years or so. Meanwhile I also found Tucker from London Science Museum 2013.
