Sky's not the limit for Felix's leap
The Austrian daredevil Felix Baumgartner (pictured below) will make a death-defying leap from the edge of space today as he attempts to complete the highest, fastest skydive in history.
Baumgartner (43) will jump from a helium-filled balloon 23 miles above the Earth's surface. On his way down, the man nicknamed Fearless Felix will become the first human to break the sound barrier without the aid of an aircraft.
Cameras will be attached to Baumgartner's specially designed suit and live footage of his descent will be broadcast online.
During his jump, over desert in New Mexico, temperatures will be as low as -56C. If his suit rips, potentially lethal bubbles could form in his blood. If he goes into a spin, he risks blood vessels bursting in his eyes and brain.
Planning has taken five years and he successfully completed a test jump from 18 miles up in July. (© Daily Telegraph, London)
