The weather in New Mexico appears to be good for a daredevil trying to become the first skydiver to break the sound barrier.
Meteorologist Don Day said the weather forecast remained positive for former Austrian paratrooper Felix Baumgartner's jump, scheduled for early on Sunday near Roswell, New Mexico.
Baumgartner will be prepared at sunrise to launch his helium balloon to hoist a 1,350kg capsule that will carry him 37 kilometres up in the sky. The jump has been cancelled twice due to high winds, once damaging the balloon and forcing use of a backup for Sunday's planned launch.
Baumgartner will try to break a 1960 high-altitude parachuting record. He will also test a pressurised suit that is designed for stratospheric jumps.
He called Tuesday's postponement nerve-wracking but said Sunday's date was one already steeped in aviation history. On October 14, 1947, an experimental rocket plane piloted by Chuck Yeager broke the sound barrier for the first time over Edwards Air Force Base in California.
'I want to break the speed of sound, no matter what it takes,' he said in a statement. 'As long as we have a spare balloon and more launch days, I'm good.'
