Project Space Planes is a publicity stunt, but a fun and interesting one at that. Launch 100 paper planes with a particular brand of memory cards containing messages sent in from people across the Internet on a high altitude weather balloon and see what happens. Well, it’s been a couple of weeks since they launched and results are still streaming in. Currently the list includes a number of unconfirmed reports of planes found in places like Germany, Australia, Russia, India, the Netherlands, California, Canada, and South Africa.[via /.]
