The world is turning to YouTube to watch Felix Baumgartner's daring stratospheric skydive this morning.

At last count, the video-sharing site's live stream of the high-altitude jump had attracted more than 7.2 million viewers. They are currently watching the last stages of egress before Baumgartner jumps from approximately 128,000 feet.

Baumgartner is attempting to set four records: the fastest freefall (an unprecedented Mach 1), the longest sustained freefall, a free fall from the highest-ever starting point, and the highest ascent in a manned balloon.
