Bad Weather Delays Crazy Supersonic Sky-Dive

Felix Baumgartner has already sky-dived from 13 miles up and 18 miles up—so what's a leap of 23 miles that shatters the sound barrier? Well, it at least requires good weather, so the record-breaking dive has been bumped from Monday to Tuesday to avoid strong winds and rain, Space.com reports. Then the 43-year-old Austrian will ride a specially designed capsule into the stratosphere and take a leap over southeastern New Mexico.

The key for Baumgartner is to jump head-first and reach maximum speed so as to avoid an uncontrolled flat spin—which could cause brain damage and possibly kill him, the Daily Mail reports. Within 40 seconds he hopes to reach 700mph, and hit the speed of sound at around 100,000 feet. Ultimately he intends to land near Roswell. His plan after completing the feat: retire and enjoy a quiet life, which for him means working as a rescue helicopter pilot.
