Felix Baumgartner jumps from the Red Bull Stratos capsule Red Bull Stratos/Red Bull Media House

Felix Baumgartner, the Austrian pilot who free fell from a record 128,000 feet last October 14, reached an even faster speed than was originally estimated during his live jump.

In a new report issued today, the Red Bull Stratos team says Baumgartner fell at Mach 1.25. The report, the result of a three-month long analysis of mission data, provides proof that Baumgartner broke the speed of sound on his way back to Earth.

There are some other mind-warping numbers. For example, it took Baumgartner only 50 seconds to hit his maximum speed of Mach 1.25 (or 843.6 mph). He was supersonic for 30 seconds. And he free fell for 4 minutes and 20 seconds.

The final results was announced at the Red Bull Stratos Scientific Summit held at the California Science Center in Los Angeles. The wide-ranging science findings, including the first physiologic data ever captured from a human freefalling faster than the speed of sound, also led to some revisions in the initial figures from the jump, which collected knowledge for future aerospace travel while breaking numerous records (see below).

Official lift-off time: 9:28:37 MDT

Maximum overland speed rate of manned balloon/capsule: 135.7 mph

Altitude at which Baumgartner stepped off the capsule: 127,852.4 feet

Fastest speed achieved during free fall: 843.6 mph (Mach 1.25)

Time elapse before reaching speed of sound during free fall: 34 seconds

Vertical distance of free fall: 119,431.1 feet

Time to reach maximum speed (Mach 1.25): 50 seconds

Duration of supersonic velocity: 30 seconds

Duration of “flat” spin: About 13 seconds

Total time spent in free fall: 4 minutes 20 seconds

Chute pulled: 8,421.3 feet above sea level (approx. 5,000 feet above ground level)

Total time from the moment he jumped to landing: 9 minutes 18 seconds

Total time from launch of balloon to Baumgartner’s landing: 2 hours 47 minutes

Minimum temperature (at 59,721 feet): -95.62 Fahrenheit
