"It's not every day that a giant paper airplane is released high over the Arizona desert. In fact, it's never been done. But that's exactly what the Pima Air & Space Museum did," the museum wrote on its wonderfully named Web site, GreatPaperAirplane.org. "A couple months ago, hundreds of kids came to the museum to show us what paper airplane flying was all about. And now, inspired by their enthusiasm, we built a 45-foot paper airplane (quite possibly the largest ever constructed) and flew it."
