The Boeing 747 is a widebody commercial airliner, often referred to by the nickname "Jumbo Jet". It is among the world's most recognizable aircraft,and was the first widebody ever produced. Manufactured by Boeing's Commercial Airplane unit in the US, the original version of the 747 was two and a half times the size of the Boeing 707,one of the 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. It 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 (as is the general rule today) 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 did so because the company expected supersonic airliners, whose development was announced in the early 1960s, to render the 747 and other subsonic airliners obsolete, but that the demand for subsonic cargo aircraft would be robust into the future. The 747 in particular was expected to become obsolete after 400 were sold but it exceeded its critics' expectations with production passing the 1,000 mark in 1993. As of October 2008, 1,409 aircraft had been built, with 115 more in various configurations on order.
The 747-8 officially announced in 2005, the 747-8 is the fourth-generation Boeing 747 version, with lengthened fuselage, redesigned wings and improved efficiency. The 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest passenger aircraft in the world.
The 747-8 is offered in two main variants: the 747-8 Intercontinental (747-8I) for passengers and the 747-8 Freighter (747-8F) for cargo. The first 747-8F performed the model's maiden flight on February 8, 2010 with the 747-8 Intercontinental following on March 20, 2011.
The 747 is to be replaced by the Boeing Y3 (part of the Boeing Yellowstone Project) in the future.
