Adventurer Jonathan Trappe's bid to cross the Atlantic using helium balloons is being tracked online. You can view Jonathan's progress via a website that is following his journey, which began from Caribou, Maine on Thursday morning.
The 39-year-old is relying on 370 helium-filled balloons as he attempts to complete the 2,500 mile trip, which should take between three to five days. Due to weather his final destination is not known.
Despite heavy fog, the aviator achieved lift-off at 6.20am this morning from Caribou, Maine but his final destination is still unknown. The flight had been delayed by 100 days due to adverse weather conditions.
Before the launch, Mr Trappe said: "Weather is absolutely the most dangerous factor. But it's a double-edged sword. It's the only thing that will carry me across, but bad conditions could also ruin the attempt or endanger my life."
The adventurer already holds the record for the longest ever cluster balloon flight at 14 hours and crossed the English Channel in May 2010 by using balloons.
Disney's 2009 hit animation film 'Up' tells the story of widower Carl Fredricksen, who tied thousands of balloons to his house in a bid to see the world.
