The History Of Boeing 747 ( Video Biography) – Largest Dams

The Boeing 747 is an American wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, “Jumbo Jet”. Its distinctive hump upper deck along the forward part of the aircraft has made it one of the most recognizable aircraft, and it was the first wide-body airplane produced. Manufactured by Boeing‘s Commercial Airplane unit in the United States, the 747 was originally envisioned to have 150 percent greater capacity than the Boeing 707, a common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.

The four-engine 747 uses a double-deck configuration for part of its length and is available in passenger, freighter and other versions. Boeing designed the 747’s hump-like upper deck to serve as a first–class lounge or extra seating, and to allow the aircraft to be easily converted to a cargo carrier by removing seats and installing a front cargo door. Boeing expected supersonic airliners—the development of which was announced in the early 1960s—to render the 747 and other subsonic airliners obsolete, while the demand for subsonic cargo aircraft would remain robust well into the future…..
