Space jumper Felix Baumgartner has again postponed plans to make his record bid to skydive from the edge of space back to Earth - because of unsafe climate conditions.
Organisers at Red Bull Stratos had hoped to make another attempt to send a balloon carrying Baumgartner to a height of 23 miles above the surface of the Earth. An earlier attempt was postponed because of adverse weather conditions.
Now, the rescheduled jump has been cancelled because of continuing poor weather.
A spokesman said: "The next weather window for another launch attempt opens on Sunday October 14th."
The balloon designed to carry Baumgartner is so delicate that it cannot operate in winds above 2mph. The balloon is 55 storeys high.
Wearing a pressurised suit, the Austrian daredevil hoped to launch himself from the balloon and drop at speeds of up to 690mph before opening his parachute and landing in the New Mexico desert.
If successful, he would set a record as the first man to break the sound barrier without mechanised support.
If he failed, he would burn up in the atmosphere.
The 33-year-old skydiver and Base jumper made a name for himself in 1999 by setting a record for a parachute jump from top of the 450m (1,500ft) Petronas Towers in Kuala Lumpur, at the time the tallest building in the world.
