Last surviving hero of Telemark remembers the 1942 mission

When two gliders carrying British soldiers crashed over occupied Norway in late 1942, those that did not die on impact were executed by the Nazis.

But the mission they were on was considered so important to the future of the war, that British military planners knew they would have to try again.

One of the men they turned to was Joachim Ronneberg, a Norwegian who had fled to Britain and wanted to return home to fight.

The last surviving Hero of Telemark - the operation in Norway to stop Germans developing nuclear weapons, remembers the events 70 years on.
