Leave it to RedBull to pull the most spectacular stunt you've never even thought of. Well they've done it again, this time by attaching a small skate park to the bottom of a hot air balloon, and letting BMX superstar Kriss Kyle loose to have some fun... 2,000 feet up in the air. 

Kriss Kyle, also known as the "Scottish Wildcat," is one of the world's premiere BMX bikers, and believe it or not he's scared of heights - but probably not much else. "I’ve had to push past my fears several times before on Red Bull projects, but nothing has compared to this,” he said. "By far this is the biggest challenge that I've ever faced in my life."

On top of trusting his BMX skills to take over when the time comes, he has trust in those around him. "With a project like this you need a strong team behind you," he said, "and I literally trust those boys with my life." At 2,000 feet in the air, it's a good thing he does. And for shots like these, I think it was all worth it.
