The Boeing 747 is a jet airliner. It is made by Boeing Commercial Airplanes. The Boeing 747 has more than one aisle, which means it is a wide-body aircraft. It is often called the Jumbo Jet or Queen of the Skies. The Boeing 747 is one of the easiest planes in the world to recognise. It was the first wide-body aircraft ever made. The first type of 747 was two and a half times the size of the Boeing 707. The Boeing 747 made its first flight for an airline in 1970. The 747 could carry more passengers than any other aircraft for 37 years, until the Airbus A380 was made.
