The standard of luxury on Pan American's Boeing 314s has rarely been matched on heavier-than-air transport since then they were a form of travel for the super-rich, priced at $675 return from New York to Southampton (comparable to a round trip aboard Concorde in 2003). Men and women were provided with separate dressing rooms, and white-coated stewards served five and six-course meals with gleaming silver service. The Boeing 314s had a lounge and dining area, and the galleys were crewed by chefs from four-star hotels. ![]() The seats could be converted into 36 bunks for overnight accommodation with a cruising speed of 188 miles per hour (303 km/h) (typically flights at maximum gross weight were flown at 155 miles per hour (249 km/h)) in 1940 Pan Am's schedule San Francisco to Honolulu was 19 hours. Pan Am's Boeing 314 "Clippers" were built for "one-class" luxury air travel, a necessity given the long duration of transoceanic flights. A capacity of 300 US gallons (1,100 L 250 Imp gallons) of oil was required for operation of the radial engines. The later Boeing 314A model carried a further 1,200 US gallons (4,500 L 1,000 Imp gallons.). To fly the long ranges needed for trans-Pacific service, the Boeing 314 carried 4,246 US gallons (16,070 l 3,536 imp gal) of gasoline. Passengers and their baggage were weighed, with each passenger allowed up to 77 pounds (35 kg) free baggage allowance (in the later 314 series) but then charged $3.25 per lb ($7.15/kg) for exceeding the limit. The sponsons, broad lateral extensions at the waterline on both sides of the hull, served several purposes: they provided a wide platform to stabilize the craft while floating on water, they acted as an entryway for passengers boarding the flying boat and they were shaped to contribute additional lift in flight. Boeing also incorporated Dornier-style sponsons into the hull structure. The Boeing 314 used a series of heavy ribs and spars to create a robust fuselage and cantilevered wing, obviating the need for external drag-inducing struts to brace the wings. This too was found to be lacking and finally the centerline vertical fin was restored, after which the aircraft flew satisfactorily. The aircraft returned to the factory and was fitted with the endplates on the ends of the horizontal tail in place of the single vertical fin. At first the aircraft had a single vertical tail, and Allen found he had inadequate directional control. The first flight was on June 7, 1938, piloted by Edmund T. The huge flying boat was assembled at Boeing's Plant 1 on the Duwamish River in Seattle, and towed to Elliott Bay for taxi and flight tests. Pan Am ordered six more aircraft with increased engine power and capacity for 77 daytime passengers as the Boeing 314A. Boeing engineers adapted the cancelled Boeing XB-15's 149 ft (45 m) wing, and replaced the 850 hp (630 kW) Pratt & Whitney Twin Wasp radial engines with the 1,600 hp (1,200 kW) Wright Twin Cyclone. Boeing's bid was successful and on July 21, 1936, Pan American signed a contract for six aircraft. Pan American had requested a flying boat with unprecedented range that could augment the airline's trans-Pacific Martin M-130. (BOAC's 3 Short S.26 transoceanic flying-boats had been requisitioned by the RAF). The remaining three were sold to British Overseas Airways Corporation (BOAC) by Pan Am and delivered in early 1941. Twelve Clippers were built nine were brought into service for Pan Am and later transferred to the U.S. One of the largest aircraft of the time, it used the massive wing of Boeing's earlier XB-15 bomber prototype to achieve the range necessary for flights across the Atlantic and Pacific Oceans. The Boeing 314 Clipper was a long-range flying boat produced by the Boeing Airplane Company between 19.
