In the mid-1930s, in the wake of the rapid growth in passenger air travel, the Boeing Aircraft Company, while busy with the design of a modern four-engine bomber, worked simultaneously on the creation of a new four-engine aircraft, purposed for civil aviation. Innovative engineering directly affected the design of the aircraft fuselage - for the first time in a machine of this type, a pressurized cabin was utilized, which enabled a significant increase in altitude in flight, allowing greater safety and a minimization of collision with thunderstorms, which flights were affected by at lower levels. The new aircraft, according to designers, could safely fly at an altitude of more than 7,500 meters, where the more dangerous atmospheric phenomena were absent. The first flight of the aircraft took place on the last day of 1938, but shortly afterwards a catastrophe resulted
