The Boeing 314 (known erroneously as the Clipper, after the name given by Pan American World Airways) was a long-range flying boat produced by the Boeing Airplane Company between 1938 and 1941 and is comparable to the British Short Empire. One of the largest aircraft of the time, it used the massive wing of BoeingÌÎ_Ì´ÌàÌÎ_Ì´åÇs earlier XB-15 bomber prototype to achieve the range necessary for flights across the Atlantic and Pacific Oceans. Twelve Clippers were built for PanAm, three of which were sold to BOAC in 1941 before delivery.
