Watch Austrian daredevil Felix Baumgartner skydive from 38 kilometres (24 miles) above Roswell, New Mexico.
As the Red Bull Stratos project began, Baumgartner was lifted in a capsule attached to a giant helium balloon on Sunday, Oct. 14.
In a specially made suit, he is attempting the highest parachute jump in history, hoping to become the first skydiver to break the sound barrier.
"The near absence of air at this high altitude means he should break the speed of sound as he falls - a velocity in excess of 690mph (1,110km/h)," according to the BBC.

The 43-year-old has been training for five years to make this jump.
Baumgartner's ascent is expected to take up to three hours. His descent, however, will only last for about 10 minutes — half of it will be in freefall, without a parachute. According to the CBC, he "is expected to break the sound barrier in the first 30 seconds after leaving the capsule."
