75 cars break doughnut record in Calif.

SONOMA, Calif., March 22 (UPI) -- A California raceway said 75 cars gathered on the tarmac and performed simultaneous doughnuts to set a Guinness World Record.

The Infineon Raceway in Sonoma said the participants Tuesday beat the 2010 record of 57 cars performing simultaneous doughnuts in Queensland, Australia, and evidence has been submitted to Guinness to make the new record official.

The cars spun in small circles for more than 15 seconds in front of more than 200 spectators.

"That was a blast. With all the smoke and all the cars doing donuts simultaneously; I've never seen anything as big as that," said Calvin Wan, a professional drifter from San Francisco. "That was just a great time."

Bird-like wings carry man 330 feet

THE HAGUE, Netherlands, March 22 (UPI) -- A Dutch man said he completed a flight of about 330 feet using homemade wings based on those of a bird.

Jarno Smeets, 31, an engineer, said he controlled the 55-foot wings using two Nintendo Wii controllers, the accelerometers from an HTC Wildfire S smartphone and Turnigy motors when he took off Sunday at a park in The Hague and flew for about a minute.

"Ever since I was a little boy I have been inspired by pioneers like Otto Lilienthal, Leonardo da Vinci and also my own grandfather," Smeets said.

Smeets has been chronicling his progress on the Human Bird Wings project on YouTube.

Group makes sleeper car on subway

NEW YORK, March 22 (UPI) -- New York "prank collective" Improv Everywhere released video to YouTube of members converting a commuter train into a subway sleeping car.

The group, which describes itself as a "prank collective" aimed at staging "scenes of chaos and joy in public places," said founder Charlie Todd and accomplices boarded an N train around midnight in February and set up three folding cots with pillows, sheets and comforters in the aisle of the moving train, the New York Daily News reported Wednesday.

"We had no idea how people would react," Todd said of the stunt. "Many people took us up on the offer of taking a little nap."

The stunt was sponsored by the Guggenheim Museum as part of its public events series titled "stillspotting nyc."

The pranksters did not encounter any police or Metropolitan Transportation Authority officers, but officials said the group would have been ticked if officials had seen them.

"This was a YouTube moment that should have resulted in the receipt of a fine," MTA spokesman Charles Seaton said. "Aside from the obvious tripping hazard, placing any large and bulky item in an area of limited space could cause extreme difficulty for customers in the event of an emergency."

World's longest bridal train: 1.85 miles

BUCHAREST, Hungary, March 22 (UPI) -- Guinness World Records said the world's longest bridal train, measuring 1.85 miles, was displayed at a Wedding Fair in Hungary.

The organization said the dress, which was displayed at the Bucharest Wedding Fair, was longer than the previous record holder, a 1.54-mile-long bridal train created by a Dutch designer, CNN reported Wednesday.

The creators of the train, which was displayed by a model riding in a hot air balloon, said a team of 10 seamstresses spent 100 days creating the item.
