This Navy-funded drone is at home in sea and sky

We've all heard of amphibious cars, but what about amphibious drones? Researchers at Rutgers University took on the challenge of building an unmanned vehicle that can soar through the air and seamlessly transition to swim through the water. They call it the Naviator. In fact, inventors have been playing with the idea since the 1930s, when Boris Ushakov, a student engineer at a Soviet military academy, proposed a three-engine floatplane that could flood its fuselage to sink beneath the water and torpedo its enemies when they got close. The project was scrapped before it was ever built.
