The Boeing 747 is a large, long-range commercial jet airliner developed by Boeing, recognizable by its distinctive upper-deck hump and four-engine design.

Wide-body aircraft: An airliner with a cabin wide enough for multiple passenger aisles. The 747 helped establish the wide-body airliner category.
Boeing 2707: Boeing's proposed supersonic transport, developed during the 1960s but never built. Boeing pursued the 747 after losing the government contract for this aircraft.
Boeing 747-100: The initial production variant of the Boeing 747. It introduced the basic passenger configuration and proportions of the family.
Boeing 747 freighter: A cargo aircraft variant of the 747 designed to carry freight rather than passengers. The 747's size and nose-loading option made it useful for oversized cargo.
Jumbo jet: An informal name for a very large commercial jet airliner, especially the Boeing 747. The 747 became the aircraft most closely associated with the term.
Jet engine: An engine that produces thrust by accelerating a stream of gas rearward. Four jet engines powered the 747's original long-range design.
Juan Trippe: The Pan American World Airways executive who led the airline from 1946 to 1968. Trippe pressed Boeing to build a much larger airliner for Pan Am.
Boeing 747-400: A long-range 747 variant introduced in 1989 with a two-person flight deck and winglets. Its redesign improved range and reduced cockpit crew requirements.
Boeing 747-200B: A long-range passenger variant of the 747-200 series. Airlines used it on high-capacity international routes.
Air travel: Passenger or cargo transportation by aircraft. The 747's high capacity changed how airlines planned long-distance service.
