Make Your Career Soar

Sixty years ago this week, USAF Captain Joseph W. Kittinger, Jr. successfully completed a daring parachute jump from 102,800 feet (19.5 miles). The historic bailout took place over the Tularosa Basin of New Mexico.

Kittinger’s jump was the final mission of the three-jump Project Excelsior flight research effort which focused on manned testing of the Beaupre Multi-Stage Parachute Parachute (BMSP). The system was being developed to provide USAF pilots with a means of survival from an extreme altitude ejection.

Transport to jump altitude was via a 3-million cubic foot helium balloon. Kittinger rode in an open gondola. He was protected from the harsh environment by an MC-3 partial pressure suit as well as an assortment of heavy cold-weather clothing. Kittinger and his jump wardrobe and flight gear weighed a total of 313 pounds

The Excelsior III mission was launched just north of Alamogordo, New Mexico at 11:29 UTC on Tuesday, 16 August 1960. Ninety-three minutes later, Kittinger’s fragile balloon reached float altitude. At 13:12 UTC, Kittinger stepped out of the gondola and into space. As he did so, he said: “Lord, take care of me now!”

The historic record shows that Joe Kittinger experienced a free-fall that lasted 4 minutes and 36 seconds. During this time, he fell 85,300 feet (16.2 miles). Incredibly, Kittinger reached a maximum free-fall velocity of 614 miles per hour (Mach 0.92) passing through 90,000 feet.

The BMSP worked as advertised. Kittinger entered the cloud deck obscuring his Tularosa Basin landing point at 21,000 feet. Main parachute deployment occurred at 17,500 feet. Total elapsed time from bailout to touchdown was 13 minutes and 45 seconds.

While Joe Kittinger and the Excelsior team focused on flight testing technology critical to the survival of fellow aviators, a byproduct of their efforts were aviation records that stood for over 50 years. Those achievements include: highest parachute jump (102,800 feet), longest free-fall duration (4 minutes 36 seconds – this record still stands), and longest free-fall distance (85,300 feet).
