Hundreds of multicoloured balloons used Thursday to launch a balloonist for a transatlantic crossing look like a page taken from the script of the movie Up.

Instead of using a conventional hot-air balloon, Jonathan Trappe lifted off using more than 300 helium-filled balloons, like those used in the animated movie.

Trappe's goal is to float across the ocean.

"The Atlantic Ocean has been crossed many times, and in many ways, but never quite like this," the North Carolina native said on his website, which detailed his efforts.

City Manager Austin Bleess said about 150 volunteers assisted in filling the helium balloons starting Wednesday night. Trappe and his balloons lifted off from a foggy softball field in northern Maine, near the Canadian border, at sunrise Thursday.

"Man, it was awesome," Bleess said. "It was amazing to watch."

On Thursday night, Trappe wrote on his Facebook page that he had landed safely at a remote location and would spend the night there. He didn't say where he was.

On hand for Trappe's lift off was Joe Kittinger, a retired air force officer who once set a record for jumping from a balloon 31 kilometres up and later became the first solo balloonist to cross the Atlantic in 1984.

As for Trappe, he's no stranger to the cluster balloons.

He's used them to fly in an office chair, and he's used them to lift a faux house, just like in the Disney-Pixar movie. In 2010, he crossed the English Channel using a cluster of balloons. For his transatlantic crossing, the basket in which he's riding is actually a lifeboat that could be used if he ditches in the ocean.

Trappe worked on the transatlantic crossing for two years and hoped to be the first person to succeed in doing so with a cluster of balloons. By Thursday evening, he was well on his way, headed toward Newfoundland.

The airborne journey, if it goes according to plan, could take anywhere from three days to six days. Wind currents could bring him to northern Africa or Norway.
