Passersby walking along the River Thames must have been surprised by the feat of two parachutists dressed in wingsuits. Two Austrians, Marco Furst and Marco Waltenspiel, jumped from a helicopter at a height of three thousand feet to fly over the course of the river and cross London’s Tower Bridge at several hundred kilometers per hour.

A wingsuit or wingsuit is a winged suit used for gliding, as a form of skydiving. The horizontal displacement in this modality increases while the vertical descent decreases, compared to traditional free fall skydiving.

In the case in question, they completed a maneuver called “flare”, which consists of descending to a height of 35 meters to rise again to 80 meters, at which time it was decided to open the parachute and land properly on the ground. The images in the video that accompanies this article speak for themselves.
