Today, Felix Baumgartner is attempting to break the world record for the highest and fastest skydive, from 23 miles up -- that's from the edge of space. The best bit is you can watch the whole shebang right here, live.
Baumgartner attempted to launch his death-defying feat yesterday, but couldn't because of some bad wind.
He's It's looking a bit calmer today, apparently, which should mean things go without a hitch and he breaks 690mph on his way down. Right now final preparations are still underway; lets hope whoever packs his parachutes gets it right, or that'll be one deep, human-sized hole in the ground.
If all goes to plan, Baumgartner will be the first man in history to break the sound barrier, without an aeroplane or a rocket -- that really is incredible. It all kicks off at 13.30pm BST, so come back then and live the amazing feat with us.
Update: Looks like the wind is just too strong to launch, we'll try again tomorrow.
