The automatic parachute opener in his equipment saved his life. He went into a flat spin at a rotational velocity of about 120 rpm, the g-forces at his extremities having been calculated to be over 22 times the force of gravity, setting another record. [9] Excelsior II: On December 11, 1959, Kittinger jumped again from about 74,700 feet (22,800 m).
It also provides non-MFF personnel with a ram-air parachute that is static-line deployed.

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 first, from 76,400 feet (23,300 m) in November 1959 was a near tragedy when an equipment malfunction caused him to lose consciousness, but the automatic parachute saved him (he went into a flat spin at a rotational velocity of 120 rpm; the g-force at his extremities was calculated to be over 22 times that of gravity, setting another record ...
The steerable parachute or parafoil is called a "decelerator," and gives the JPADS system directional control throughout its descent by means of decelerator steering lines attached to the Autonomous Guidance Unit (AGU). They create drag on either side of the decelerator, which turns the parachute, thus achieving directional control.
