Philippe Petit - Man On Wire

WIKI: He walked the wire for 45 minutes, making eight crossings between the towers, a quarter of a mile above the sidewalks of Manhattan. In addition to walking, he sat on the wire, gave knee salutes and, while lying on the wire, spoke with a gull circling above his head.

As soon as Petit was observed by witnesses on the ground, the Port Authority Police Department dispatched officers to take him into custody. One of the officers, Sgt. Charles Daniels, later reported his experience:

 I observed the tightrope 'dancer'—because you couldn't call him a 'walker'—approximately halfway between the two towers. And upon seeing us he started to smile and laugh and he started going into a dancing routine on the high wire....And when he got to the building we asked him to get off the high wire but instead he turned around and ran back out into the middle....He was bouncing up and down. His feet were actually leaving the wire and then he would resettle back on the wire again....Unbelievable really....Everybody was spellbound in the watching of it. 

Wiki: Although movie cameras were on the roof during the walk, the person who was supposed to film the walk did not do so, apparently due to exhaustion from pulling the heavy cable tight after some of it had fallen, creating slack while the rigging was being set up.
