Baumgartner starts bid to break sound barrier

Extreme athlete Felix Baumgartner has started his bid to become the first skydiver in history to break the sound barrier.

The 23-mile (37km) high jump over New Mexico was postponed on Monday and Tuesday because of unexpected winds.

If successful, “Fearless Felix” will break a 52-year-old altitude record by Joe Kittinger, who jumped from 19.5 miles (31km) and reached a speed of 614 mph (988kph), just under the sound barrier.
