- A 747-400 has six million parts, half of which are fasteners.
- A 747-400 has 171 miles (274 km) of wiring and 5 miles (8 km) of tubing.
- A 747-400 consists of 147,000 pounds (66,150 kg) of high-strength aluminum.
- The 747-400 has 16 main landing gear tires and two nose landing gear tires.
- The 747-400 tail height is 63 feet 8 inches (19.4 m), equivalent to a six-story building.
- The 747-400 wing weighs 95,000 pounds (43,090 kg), more than 30 times the weight of the first Boeing airplane, the 1916 B&W.
- The 747-400 wing measures 5,600 square feet (524.9 m 2 ), an area large enough to hold 45 medium-sized automobiles.
- Four World War I vintage JN4-D "Jenny" airplanes could be lined up on each of the Boeing 747 wings.
- How much weight does an additional 6-foot (1.8-m) wingtip extension and winglet add to the 747-400 wing? None! A weight savings of approximately 5,000 pounds (2,270 kg) was achieved in the wing by using new aluminum alloys, which offset the weight increase of the wing tip extension and winglet
More detailed info
The Boeing 747, commonly nicknamed the "Jumbo Jet", is a long-haul, widebody commercial airliner manufactured by Boeing. Known for its impressive size, it is among the world's most recognizable aircraft. First flown commercially in 1970, it has held the passenger capacity record for 37 years and was the first commercial wide-body aircraft.
The four-engine 747, produced by Boeing's Commercial Airplane unit, uses a double decker configuration for part of its length. The hump created by the upper deck has made the 747 a highly recognizable icon of air travel. A typical three-class layout accommodates 416 passengers, while a two-class layout accommodates a maximum of 524 passengers.
The 747-400, the latest version in service, flies at high-subsonic speeds of Mach 0.85 (567 mph or 913 km/h), and features an intercontinental range of 7,260 nautical miles (8,350 mi, 13,450 km).
The 747 was expected to become obsolete after sales of 400 units, but it has outlived many of its critics' expectations and production passed the 1,000 mark in 1993. As of June 2007 1387 planes had been built, with 120 more in various configurations on order. The latest development of the aircraft, the 747-8, is planned to enter service in 2009.
