Joseph Kittinger Took a 102,800-Foot Step Into the Unknown
Joseph Kittinger’s 1960 Project Excelsior jump tested whether a pilot could survive escape from the edge of space.
In 1960, nobody could be certain how a human body and parachute would behave after an emergency escape from the edge of space. U.S. Air Force Captain Joseph Kittinger volunteered to find out.
Project Excelsior III
On 16 August, a helium balloon lifted Kittinger in an open gondola to 102,800 feet above New Mexico. He stepped out wearing a partial-pressure suit and descended safely using a stabilising drogue and main parachute.

The mission tested equipment intended to save pilots at extreme altitude.
A test with real consequences
Kittinger’s first Excelsior jump had nearly killed him when equipment trouble sent him into a flat spin and he lost consciousness. The automatic parachute system saved him.
He returned to the programme, helping prove a multi-stage parachute concept in which a small drogue stabilised the body before the main canopy opened in denser air. The research informed high-altitude aviation and later spaceflight safety.
Beyond one famous photograph
Kittinger later flew combat missions in Vietnam, became a prisoner of war and pursued long-distance ballooning. In 1984 he completed the first solo balloon crossing of the Atlantic.
Decades after Excelsior, he advised Red Bull Stratos and spoke with Felix Baumgartner throughout the 2012 ascent. Knowledge from one generation became operational guidance for the next.
The geek lesson
Kittinger’s obsession was not risk for its own sake. It was measurement: pressure, altitude, stability, suit performance and parachute timing. His willingness to test the system turned an extraordinary fall into useful aerospace knowledge.
