Men with dynamite

Duration: 01:24

In Switzerland there are an estimated 30,000 of avalanches each year.

At the forefront of avalanche control in Switzerland are highly specialised people who risk their lives each day. These are the alpine Ski Patrollers; experts who must have an intimate knowledge of local weather patterns and the unique geography of the Alps. They have learnt how to deal with avalanches before they become killers – by detonating explosives on high mountain slopes releasing tonnes of snow which might otherwise kill skiiers and people living in the villages below.

Martin and his colleague can read the snow and spot its weak line on the slopes but in this clip they show that even the experts can get things wrong!
