History came in a flash Wednesday night.

Jamaican sprinter Usain Bolt stunned a crowd of 91,000 at National Stadium on Wednesday, powering his way to a 200-meter gold medal to become the first man since Carl Lewis in 1984 to win an Olympic sprint double.

Bolt had won the 100 four days earlier, breaking the world record even as he cavalierly showboated before hitting the finish.

This time, he was all business, pushing his 6-foot-5 body across the line in 19.30 seconds to eclipse Michael Johnson's record, set 12 years ago at the Atlanta Games, by 0.02 of a second.

"I told myself, 'If I'm going to break the world record, it's going to be here because this track is really fast,' " Bolt said.

"I felt like I was swimming, and I just kept telling myself, 'Don't die, don't die.' "

Bolt threw his arms into the muggy air after his historic run, flopped onto his back, pulled himself to his knees and kissed the track.

He then boogied around the oval as fans sang Happy Birthday to the soon-to-be 22-year-old. It's the first time in Olympic history one sprinter has broken both world records at a single Games.

"It means a lot to me and my country," he said. "I spoke to the prime minister, and he said everyone's in the streets. He told me I have written history pretty much."

Lost in the jubilation was the fact Churandy Martina of Netherlands Antilles and Wallace Spearmon of the U.S. crossed the finish line second and third, but both stepped out of their lanes.

After a flurry of protests, American Shawn Crawford, who had been fourth, was awarded the silver and U.S. teammate Walter Dix jumped from fifth to third, giving the U.S. two medals instead of one.

But the night belonged completely to Bolt, who joins Michael Phelps as the master of 2008.

"I'm on the track, he's in the water. You can't compare it," Bolt said.

Bolt fired an imaginary arrow into the sky as he approached the blocks, but the frivolity ended there.

Off and humming from the start, Bolt came into the straightaway like a blur, then ratcheted it up another notch, unlike Saturday, when he coasted the final 20 meters.

A replay showed Jamaica's hero glancing at the clock, apparently checking to see if Johnson's record was tumbling.

"I left everything on this track," he said.
