America in World War I: NC-3 and NC-4 in front of their hangar ready for...

NC-3 and NC-4 in front of their hangar ready for the trans-Atlantic flight. The NC seaplanes, at the time of the flight, the largest flying boats in existence, were developed by naval constructors in cooperation with the Curtiss Aeroplane and Motor Corporation, by whom they were built. Originally designed for long-distance operations oversea, the first was completed in September, 1918, thoroughly tested in October, and on a flight in December carried up 51 passengers. Four of these flying boats were built, three being assigned to the trans-Atlantic flight.
