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 ...
While performing a high speed landing manoeuvre, his automatic activation device fired at approximately 750 feet (230 metres) above the ground and deployed his reserve parachute. He attempted to correct the situation by releasing his main parachute, however, he still hit the ground hard enough that he died at the scene as a result of his injuries.

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).
