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 descent speed.

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.
A six-man stick of team operators from 1st Force Recon perform a 'high-altitude, low-opening' (HALO) parachute insertion jump at ≈22,000–30,000 ft. above sea-level. —circa 2004. Throughout training and real life operations, jet fins, snorkels and low-volume double lens dive masks are used. [47]
If the parachute is deployed while the jumper is unstable, there is a high risk of entanglement or malfunction. The jumper may also not be facing the right direction. Such an off-heading opening is not as problematic in skydiving, but an off-heading opening that results in object strike has caused many serious injuries and deaths in BASE jumping.

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.
The image shows the complete multi-layer suit and positive-pressure helmet, lacking only the backpack. (taken c. 1971) A mechanical counterpressure (MCP) suit , partial pressure suit , direct compression suit , or space activity suit ( SAS ) is an experimental spacesuit which applies stable pressure against the skin by means of skintight ...
Speed skydiving is a competition discipline within the sport of skydiving. The competition objective is for the competitors to fly their body as fast as possible to achieve the highest average vertical speed through a 3-second window. The speed is measured using a speed measuring device (SMD) worn on the competitor's helmet.
