Richard Branson's First-Ever Scubacraft Flies Like A Plane Underwater (VIDEO)

Business tycoon and founder of Virgin Richard Branson is also a big-time adventurer, and now he's taking his thrill-seeking antics underwater with a scubacraft that is the first of its kind.

Oprah regular Nate Berkus went along with Branson to get an inside look at his mini-submarine/scubacraft in action. The submarine flies like a plane underwater, and since it's completely battery-driven and silent, it's also environmentally-friendly and doesn't disturb the fish.

"You're just like a fish," Branson said.
