In February this year the BBC attempted to provide the first live pictures of a winter ice climb. For seven days a film crew recorded the efforts of technicians, climbers and Royal Marines, as they struggled in 100mph winds and sub-zero temperatures. Arctic tents were smashed, helicopters iced up in mid-air; five visiting climbers were killed. The project was called off hours from success, but one man went on, French Alpinist Jean Franck Charlet.
