If watching cars race around a track at 200 mph is your idea of excitement, picture a group of rocket-powered aircraft battling each other NASCAR-style as they tear around a 3-D virtual track in the sky.

The Rocket Racing League is the brainchild of Granger Whitelaw – a guy who as team chairman won the Indianapolis 500 twice and still wasn’t getting enough RPM in his life, and Peter Diamandis who won the X-Prize, a world-wide competition for amateur rocket design. The pair parlayed their knowledge of rocketry and racing to form the RRL and are now convinced they're sitting on the next big sport.

Their concept is to take the thrill of an air show, multiply that times 100, and mix in some raw competition with a healthy dose white-knuckle action. (I'm thinking collisions during a race in this league will be a helluva lot more heart-stopping than anything you've seen in auto racing. Not that I'm rooting for that...)

The pilots? They've already signed up a handful of the most bad-ass military combat veterans and civilian test pilots in the world, just to make sure crowds get their money's worth.

The RRL will hold it's first exhibition races this summer, where you can see up to ten racing rockets battle head-to-head on a 5-mile track in the clouds. I hear Tony Stewart is already taking flying lessons.
