The Bartini Beriev VVA-14 had a three-person crew.
The plane's first flight was held on Sept. 4, 1972. At the time, the prototype had yet to be outfitted with its pontoons for aquatic landings.
The addition of the pontoons allowed the VVA-14 to land at sea.
In addition, the plane could efficiently hover along the surface of the water.
