This video is about the professional slackliner Spencer Seabrooke, who attempted to walk through a single slack line without any safety aid. He walked through the slack to beat his own record and walked for a distance of 64 meters and 290 meters off the ground.

Seabrooke definitely has nerve of steels to walk in a slackline as dangerous as this without any safety harness.
