Roden Douglas DC-7C Royal Dutch Airlines (KLM)

The Douglas DC-7C was an American four-engine plane produced in the early 1950s. The main task of this aircraft was transcontinental flight between the United States and the capitals of Europe and Asia. For a few years, the DC-7C was the flagship aircraft of the world's leading airlines, such as American Pan Am, Dutch KLM, Scandinavian SAS, and Japanese JAL. With the beginning of the jet era, the DC-7C was retired and converted into a transport and firefighting aircraft. Use of the type in developing countries continued until the end of the twentieth century. A total of 337 DC-7s of all variations were produced. This aircraft is considered a classic and one of the most important passenger aircraft of all time.
