The Boeing 747, often referred to by the nickname "Jumbo Jet", is among the world's most recognizable aircraft, and was the first wide-body commercial airliner 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, it held the passenger capacity record for 37 years, until it was surpassed by the Airbus A380.
