Consciousness is retained for up to 15 seconds as the effects of oxygen starvation set in. Counteracting this requires a helmet to contain breathing gases and protect the ears and eyes. [3] These effects have been confirmed through various accidents in very high altitude conditions, outer space, and training vacuum chambers. [4] [2]
CYPRES II panel. In skydiving, an automatic activation device (AAD) is a dead man's switch consisting of an electronic-pyrotechnic or mechanical device that automatically activates the opening sequence of the main or reserve parachute container when the AAD is falling below a preset altitude and above a preset decent speed.
Red Bull Stratos was a high-altitude skydiving project involving Austrian skydiver Felix Baumgartner.On 14 October 2012, Baumgartner flew approximately 39 kilometres (24 mi) [1] [2] [3] into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth.

A pressure suit is a protective suit worn by high-altitude pilots who may fly at altitudes where the air pressure is too low for an unprotected person to survive, even when breathing pure oxygen at positive pressure. Such suits may be either full-pressure (e.g., a space suit) or partial-pressure (as used by aircrew). Partial-pressure suits work ...
United States Air Force Pararescuemen jump at half the height of a typical HALO/HAHO insertion 2eme REP Legionnaires HALO jump from a C-160.. High-altitude military parachuting, or military free fall (MFF), is a method of delivering military personnel, military equipment, and other military supplies from a transport aircraft at a high altitude via free-fall parachute insertion.
The Military Freefall Parachutist Badge is a military badge of the United States Army and United States Air Force awarded to qualified U.S. Army and U.S. Air Force personnel as high-altitude military parachute specialists. [2] [3]
The Mercury space suit (or Navy Mark IV) was a full-body, high-altitude pressure suit originally developed by the B.F. Goodrich Company and the U.S. Navy for pilots of high-altitude fighter aircraft. It is best known for its role as the spacesuit worn by the astronauts of the Project Mercury spaceflights.
He held the world record for the highest skydive—102,800 feet (31.3 km)—from 1960 until 2012. [1] [2] He participated in the Project Manhigh and Project Excelsior high-altitude balloon flight projects from 1956 to 1960 and was the first man to fully witness the curvature of the Earth.
