A small helicopter that can take off underwater from a submarine and hold two passengers - designed jointly by students at the Technion-Israel Institute of Technology in Haifa and the University of Pennsylvania - has won first prize in a US helicopter design competition.

Called "Waterspout," the helicopter can be stored inside the submarine without taking up too much space. It is released through existing openings in the submarine, so no new ones have to be made.
The helicopter is autonomous, can function in a variety of weather conditions and can be dispatched from a submarine from some 15 meters under the water's surface (enough for a periscope to see into the air from under the water.)
