If you chance upon a paper airplane with an SD card stuck to it sometime in the next few weeks, don't be surprised. It's part of a viral marketing effort by The Viral Factory, which was commissioned by Samsung to drop 100 paper airplanes from a weather balloon at the edge of space back to Earth. Each plane will have an attached SD card (Samsung branded, of course) carrying a message--pictures, videos, music, whatever--uploaded by the public to the Project Space Planes Web site.
Samsung says it's pulling off the stunt to prove how tough its memory cards are. The exact site 21 miles above the Earth where the paper planes will be set loose has yet to be announced, but the marketing company has engaged Andy Chipling, an expert in dabbling with paper planes, to ensure that when released, the planes will be able to travel the longest possible distance.
So keep on the lookout for any paper planes, and if you find one, let Samsung know here and the company says it will get you in touch with the person who uploaded the message in the first place. Even if you don't want to participate in the project, at least you get to keep an SD card.
