The Clipper was the largest commercial transport of its time and the icon of the romantic era of flight. Pan American bought 12 of the Clippers to fly routes across the Pacific and the Atlantic, where the 314 pioneered the first scheduled transatlantic flights. The airplane's 74 passengers were pampered with staterooms, a lounge and a dining salon, and the Clipper seats could convert into 40 bunks. The Clipper became the first of a long line of Boeing presidential airplanes when Franklin Roosevelt flew the Clipper to the Casablanca conference in 1943.
