New footage has emerged of Felix Baumgartner's utterly insane jump from the edge of space.
The GoPro footage shows his beautifully blissful free-fall from nearly 39km up, becoming the first person to break the sound barrier without help from a vehicle, reaching Mach 1.25 (843.6 mph).
What it also shows is the terrifying and uncontrollable spin he ended up in during which he can be heard saying "I feel like I need to pass out" - which would have almost certainly resulted in his death.
Millions watched his 10 minute descent to Earth live on the Internet, after his slow ascent into the sky beneath a 55-storey balloon.
Baumgartner spent five minutes in freefall, and had to use his years of training to recover from a terrifying spin which saw him rotating faster than once per second.
His team said that the analysis has provided around 100 million data points with practical scientific applications.
"Together we proved that a human in freefall can break the speed of sound returning from near space, going through a transonic phase and landing safely on the ground," said Jonathan Clark, Red Bull Stratos medical director.
"That was a big part of the program, and monitoring the mission was a meaningful event in aerospace medicine and physiology."
Among the innovations that made the jump possible were a new parachute system, an innovative treatment for ebullism and new ventilator systems.
