Kjerag is one of the world's most popular sites for base jumpers - one of them can be seen in the upper centre part of this picture. They hike up to the plateau for 2-3 hrs, evaluate the wind conditions, calm the nerves before they (as the madmen and women they are) throw themselves off the cliff, aiming for the ground 1000m below.
This is from 2012 when we all of a sudden, as is typical for the mountains, were cloud'ed up.
