Felix Baumgartner's Airstream used for the record breaking free fall.

Some data:

Launch was rescheduled and the mission instead took place on 14 October 2012 when Baumgartner landed in eastern New Mexico after jumping from a world record 39,045 metres (128,100 ft) or just over 39 kilometres (24 mi).On the basis of provisional data, Baumgartner also set the record for the highest manned balloon flight (at the same height) and fastest speed of free fall at 1,342 kilometres per hour (834 mph) making him the first human to break the sound barrier outside of a vehicle.
