It sounds like a Hollywood concept, but DARPA wants to make the submersible aircraft a reality -- and they need your help. This week, the Defense Advanced Research Projects Agency put out a request for designs: they want a vehicle with a 2,000-pound capacity that can cover an area of about 1,000 nautical miles, fly that distance in just eight hours, and -- by the way -- fly both above and below water.
