...biggest, almost the fastest land transport plane in the U. S. It has a wingspan of 138 ft. 3 in., overall length of 97 ft. Nearly three times as heavy as the familiar DC-3, which is at present the favorite transport of all U. S. airlines, DC-4 will carry 42 passengers as a day plane, 30 passengers as a sleeper. Its top speed will be 240 m.p.h. Its 32½ tons will hurtle through the air a full mile in 15 seconds...
...With Boeing's 307, DC-4 is the first commercial transport plane with a pressurized cabin. Its passenger compartment will be kept at low-altitude air pressure for passengers' comfort while the plane flies high, above bad weather. Overweather flight has been one of commercial aviation's greatest developments in the last decade, and Douglas planes have taken the lead in making a high curve the shortest traveling distance between any two points in the U. S. DC-4 will heighten the curve, shorten the distance. Without pressurized cabins, planes now fly as high...
That DC-4 may find the actual ceiling of air traffic's enormous room was suggested fortnight ago by Arthur E. Raymond, Douglas' vice president in charge of engineering. He pointed out to the Chamber of Commerce in Washington that there are three good reasons why transcontinental transport planes will never have to fly much higher: 1) the higher they fly, the more oxygen and pressure equipment is necessary, which subtracts from potential payload (passengers and freight); 2) the overwhelming majority of U. S. passenger business is in short hauls, for which "substratosphere" flight is useless, since...
...Patterson went to competitors with his appeal: "United we fly, divided we los.e money." Six months later United, Transcontinental & Western Air, American, Eastern and Pan American signed a contract, crux of which was that for 18 months none of them would invest in any four-motored air transport between the gross weights of 43,500 lb. and 68,500 lb., other than DC-4. These lines advanced Douglas comparatively little for the experiment. Nine-tenths of the expenses, which DC-4 will have to pay back by selling itself,* have come out of the well-filled Douglas sock. None...
...next week is really the fourth DC-4. First was a "mock-up"-a full-sized wooden replica, exact in every detail, for a study of space requirements, load placement, general structure. DC-4 No. 2 was a perfect scale model, with 8 ft. 3 in. wingspan. This Lilliputian transport "flew" through 1,100 hours and $25,000 worth of wind tunnel tests at the Guggenheim Aeronautical Laboratory at Caltech. Third stage was a Spanish Inquisition by Douglas engineers, who systematically squeezed, banged, shook, stretched, heated, froze, destroyed every part, every material. They built huge testing machines many times...
