A skydiving  executive is safely back on Earth after jumping out of a giant balloon floating in the stratosphere more than 25 miles (40 km) above New , a feat that broke the sound barrier and shattered a world altitude record.

Alan Eustace, a senior vice president at the Mountain View, California-based company, was lifted up 135,890 feet (41,419 meters) by an enormous balloon shortly before dawn on Friday, the Paragon Space Development Corp said. 

After spending about 30 minutes "experiencing the wonders of the stratosphere," he plunged toward the earth, the company, which designed his custom-made pressurized spacesuit and life support system, said on its website.

The jump topped a record set by Austrian daredevil Felix Baumgartner over New  on Oct. 14, 2012 after he jumped from a height of 128,100 feet (39,045 meters).

Eustace remained in a free fall for about 4.5 minutes before landing safely nearly 70 miles from his launch point, setting a world record for the highest skydive and breaking the sound barrier in the process.

"In rapid free-fall, Alan experienced a short period of near weightlessness and within 90 seconds exceeded the speed of sound," Paragon said on its website.

He landed on the ground just 15 minutes after he was lifted into the air. 

Eustace, who has worked with  since 2002, is a pilot and skydiver, Paragon said.

"I always wondered: what if you could design a system that would allow humans to explore the stratosphere as easily and safely as they do the ocean?" Eustace is quoted as saying on the space development company's website.
