Messner and Habeler on Everest

This amazing footage was shot when Reinhold Messner and Peter Habeler made their epochal ascent of Everest without oxygen in 1978.

The pair were climbing Alpine style as part of a larger expedition, and the ascent was not without drama.

Messner became snowblind and disorientated on the descent and was lucky to make it back.
