Felix Baumgartner’s sonic boom captured

Audio from a video recording captures what is believed to be the sonic boom (heard at 00:25 in this clip) made by Felix Baumgartner as he broke through the speed of sound barrier. The footage was recorded using a video camera pointing skyward as Baumgartner accelerated to a speed of 833.9 mph (1,342.8 km/h) during his jump from the edge of space.

The 'wave form' of the sonic boom was isolated and analysis found it to be consistent with existing ‘sonic boom characteristics’ data. 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. They are using the same algorithm that NASA applies to work out the exact moment an object travels though the sound barrier. This scientific evidence is backed up by four different groups of observers on the ground that stated they heard the sonic boom. For more info go to www.redbullstratos.com.
