The sky is the limit for a new water sport in the Florida Keys.  Jetpack Adventures is giving tourists the chance to fly -- propelled by water.

Participants strap on a flight pack that is attached to a 30-foot hose. The hose is connected to a high volume pump that uses seawater as a propellant.

A certified instructor initially operates the machine with a remote control. Then visitors are taught how to pilot their own jet pack, take off, make soft turns, hover and then eventually land.

"It's been my dream since I was a kid to fly. So, it's just amazing. I can't even describe it," one customer said.

"I love the feeling of jetting up high and coming back down in a circle," another added. "I feel like a spy woman out of a James Bond film."

The Florida Keys is currently the only region in the U.S. to offer the experience. The cost for a half hour is $249.
