WASHINGTON-American Luke Aikins leapt into the void at 25,000 feet (7,600 meters) on Saturday with no parachute or wingsuit, becoming the first skydiver to land safely on the ground in a net.

Aikins — who has done movie stunts — spent a year and a half preparing the death-defying feat, plummeting at 120 miles per hour (193 kph) in Simi Valley, California.

Fox television broadcast the two-minute jump live on an hour-long reality TV special.

“Pay attention to the science and the math behind this. And we’ll show you what’s possible,” said Aikins, 42, who runs a skydiving school in Washington state, just before taking off.

There was a lot of method behind Aikins’ madness: he has made more than 18,000 skydiving jumps.

In all those years, he needed to use his emergency chute on 30 occasions.

Also an airplane and helicopter pilot, Aikins made his first tandem jump when he was 12, following with his first solo leap four years later.

Back on the ground, with his wife and family, he seemed stunned at his own bit of history-making.

“I’m almost levitating, it’s incredible. The thing that just happened. The words I want to say I can’t even get out of my mouth. All of these guys, everything that made it happen ... It’s awesome.”

Aikins also is a third-generation skydiver whose grandfather co-founded the skydiving school after returning from World War II.
