At a restaurant atop Prague City Tower in Pankrác, the tallest building in Prague, Karel Bejšovec and two friends sit down and order some coffees. They move into a blind spot where the waiters cannot see Bejšovec, who dons a helmet and turns on his camera.
Twenty seconds later, Bejšovec is on the edge of the roof, prepared to leap.
In an article for Novinky.cz, Bejšovec describes how he prepared for the jump over the course of two months. No permission was obtained from the building, the restaurant, or any authorities; Bejšovec and his team cased the restaurant over a number of visits and found vulnerabilities in their security.
It was all captured on camera: a video posted to YouTube on May 21 showcases the jump. Bejšovec was equipped with two GoPro cameras, and was also covered by a team on the ground.
After the feat, the jumper can be seen stealthily running away from the building, leaping a fence, and making his escape in a van.
Bejšovec has made over 650 jumps in the Czech Republic and around the world, many of which have been caught on camera.
