Felix Baumgartner jumped from 128,100-feet, at the edge of space, for Red Bull’s Stratos mission and during that jump, he broke the speed of sound after 34-seconds of free fall, ultimately accelerating to as high as 833.9 mph, or mach 1.24. The first video of the actual sonic boom, which can be heard at :25, has been released by Red Bull. Continue reading to see more.

A team of experts has been analyzing the soundtrack from video footage shot at the exact instant Baumgartner went supersonic and believe they have captured the noise of the first human being breaking the speed of sound. Project Director Art Thompson is now working closely with sound experts who are also examining GPS data and other telemetry information from the chest pack to verify Baumgartner’s speed and timing of the sonic boom.

Following the attempt Baumgartner couldn’t say what it felt like to smash through the sound barrier during his leap from the brink of space. The 43-year-old Austrian said his pressurized space suit prevented him from experiencing the supersonic boom as he broke the sound barrier and accelerated through the heavens at 833.9 mph. ‘It is hard to describe, because I didn’t feel it,’ Baumgartner told reporters after the jump. ‘When you’re in a dead pressure suit [with no reference points] you don’t feel anything.’
