In January 1935, "Peng Ameriksn Eyruez", one of the largest US airlines asked the company "Boeing" with a proposal to develop a new model of the "Clipper" (the so-called flying boats that have been used by air carriers) for the transatlantic line. The company "Boeing", in spite of the heavy workload, said yes, intending to design a new aircraft to use the maximum operating time, resulting in creating not included in a series of heavy bomber XB-15.
Seaplane Boeing 314 (or as it is called - "Dreamliner") was produced in the United States from 1938 to 1941 and was able to make flights at a cruising speed of 300 km / h over a distance of 6,000 kilometers. Flying boat could be in the air for more than 12 hours (!!!) and take on board 77 passengers. Note that this is even before the Second World War!
Not surprisingly, the Boeing 314 was designed for trans-Atlantic flights. And it's fun for a long (flight to Hong Kong took six days with all intermediate stops) and expensive, so all the passengers on board were served only by the upper class. Chairs were turned into bunk, separate toilets for men and women, the menu of six dishes to choose from, lounge, restaurant - all in the best houses of Paris.
