Heller 80452 Boeing B-707

The Boeing 707 was a low-wing, four-engine, narrow-body, low-wing, American-made airliner. The drive was provided by four Pratt and Whitney JT3C or JT3D engines. The flight of the prototype took place in 1954, and serial production continued in the period 1958-1979. During its course, 1,010 Boeing 707 were produced. At the time of the emergence of efficient jet engines at the turn of the 1940s and 1950s, Boeing decided - on its own, huge financial risk - to develop the first jet airliner, which could also be offered to the US military aviation as a flying tanker, under the designation KC -135. The USAAF has expressed a lot of interest and placed orders. The same was true of civil airlines, which, however, wanted to create a wider plane - this is how the Boeing 707 was created. In the course of serial production, several different versions of the aircraft were created with different versions of engines and more and more perfect avionics. Depending on the version, the Boeing 707 could take from 141 to 189 passengers. On the basis of the Boeing 707 fuselage, several military versions were also created (e.g. E-3 Sentry or E-6 Mercury), which, however, were clearly changed in relation to the civilian versions.
