context_page_description: 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 people than any other aircraft for 37 years, until the Airbus A380 was made.
  The 747 is a double deck plane. It can carry people, cargo and many other things. Boeing designed the 747's upper deck to be a first class lounge or just extra seats. They also designed the upper deck so that the aircraft could be changed into a cargo plane easily. This was done by removing seats and putting in a cargo door at the front of the plane. Boeing did this because they thought that supersonic airliners would become much more popular than the 747 and other subsonic airliners. However, they thought that subsonic cargo planes would always be popular.
context_section_description: The 747-400 was the next-generation Boeing 747 introduced in 1989. It is the best-selling variant of the Boeing 747. It includes improvements over the 747-300 including new engines, and new winglets, which improve fuel efficiency. Its length is the same as the 747-300 but the wingspan has been increased to 211 feet 5 inches. The 747-400 retains the same longer upper deck as the 747-300 (excluding frieghter versions), and came in six variants: the 747–400, 747-400F, 747-400M, 747-400D, 747-400ER, and the 747-400ERF.
