According to Wikipedia: "The Airbus A380 is a double-deck, wide-body, four-engine jet airliner manufactured by Airbus. It is the world's largest passenger airliner, and many airports have upgraded facilities to accommodate its size. It was initially named Airbus A3XX and designed to challenge Boeing's monopoly in the large-aircraft market. The A380 made its first flight on 27 April 2005 and entered commercial service in October 2007 with Singapore Airlines."
