Felix Baumgartner is attempting to break the world record for the highest and fastest freefall in history today, Sunday October 14 at 12:24 PM EDT. You can watch a live stream of the jump here (UPDATES).
The jump was postponed because of unexpected winds on Monday and Tuesday.
According to USA Today, Baumgartner "unaccustomed to freefalling while confined by a helmet and cumbersome suit... started suffering panic attacks and pulled himself off the project. He overcame his fears with the help of a sports psychologist."

Baumgartner told USA Today after a test jump from nearly 100,000 feet: "It was simple stuff. I'd put on a helmet and tell him, from one to 10, how panicked I felt. And in the end, no matter what the number was, he told me my pulse rate never changed. So it was all in my head."
UPDATE: About 3.4 million people are watching the live stream at the moment.
According to The Associated Press, a lot could go wrong:
"His blood could boil. His lungs could overinflate. The vessels in his brain could burst. His eyes could hemorrhage. And, yes, he could break his neck while jumping from a mind-boggling altitude of 23 miles."

UPDATE: Baumgartner, 43, has jumped from his 11-by-8-foot fiberglass and acrylic capsule and landed safely on earth after a supersonic leap from space.
