The Boeing 747-400 is a large, long-range wide-body airliner produced by Boeing Commercial Airplanes, as an advanced version of the original Boeing 747. The model, first introduced as the Advanced Series 300, was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and 1,000 nautical miles [nmi] (1,900 km; 1,200 mi) range increase. Northwest Airlines became the launch customer with an order for ten aircraft on October 22, 1985. The first 747-400 was rolled out on January 26, 1988, made its maiden flight on April 29, 1988, received type certification on January 9, 1989, and entered service with Northwest a month later on February 9,…

The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. It was conceived in response to the demand of Pan Am for a jet 2+1⁄2 times the size of the 707, which had been introduced in October 1958, to reduce the airline's seat cost by 30%. The design team was led by Joe Sutter, who left the 737 development program in 1965 to design the 747. In April 1966, Pan Am ordered 25 Boeing 747-100 aircraft, and in late 1966, Pratt & Whitney agreed to develop the JT9D engine, a high-bypass turbofan. On September 30, 1968, the first 747 was rolled out of the purpose-built Everett Plant, the world's largest build…

An airplane (American English), or aeroplane (Commonwealth English), also plane, is a fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller, or rocket engine. Airplanes come in a variety of sizes, shapes, and wing configurations. The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Worldwide, commercial aviation transports more than four billion passengers annually on airliners and transports more than 200 billion tonne-kilometers of cargo annually, which is less than 1% of the world's cargo movement. Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remot…
