Speed Skydiving



Marco Wiederkehr of Liechtenstein holds the world speed skydiving record with 511.63 km/h (317.91 mph).

========================



The mission, Red Bull Stratos, will take renowned athlete Felix Baumgartner to at least 120,000 feet above the earth, to the very edge of Space.

From there, he will attempt a stratospheric free fall jump - the longest in the history of man - and hopefully will become the first human to break the speed of sound with his own body.

This is a mission to overcome limits which have existed for almost fifty years, ever since the heroic achievement of the young US Air Force test pilot, Joe Kittinger, with his 1960 Excelsior mission.

Red Bull Stratos will attempt to make history and deliver valuable learnings for medical and scientific advancement that will aid the exploration of space in future years.
