The 747 is a wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, “Jumbo Jet”. Its distinctive hump upper deck along the forward part of the aircraft has made it one of the most recognizable aircraft and it was the first wide-body airplane produced.
The 747-400, the most common variant in service, has a high-subsonic cruise speed of up to 570 mph or 920 km/h with an intercontinental range of 7,260 nautical miles (8,350 statute miles or 13,450 km). The 747-8, referred to as the 747 Advanced prior to its launch, uses the same engine and cockpit technology as the 787, hence the use of the “8”. The variant is designed to be quieter, more economical, and more environmentally friendly.
