"Brits Steve Daniels, John Oates and Lester Haines just became the envy of geeks the world over. The trio 'built a one-wing glider from paper, lofted it to the edge of space at 90,000 feet with a helium balloon, and posted sound and video recordings from the plane as it glided safely back to the ground,' writes blogger Kevin Fogarty. The Register newspaper sponsored the stunt and reported each step of the process. And British defense-contractor Qinetiq supplied the cameras and testing chambers, says Fogarty."

I always wanted to do this.
