There are 6 million parts in the 747.  Three million parts are fasteners, and about half of those are rivets.
·         The wing area of the 747-400 is 5,600 square feet (524.9 m2), an area large enough to hold 45 medium-sized automobiles.
·         The diameter of the 747-engine nose cowl is 8 feet 6 inches (2.6 m).
·         Four World War I vintages JN4-D “Jenny” aircraft could be lined up on each of the Boeing 747 wings.
·         One wing of the 747 weighs 28,000 pounds (12,700 kg), 10 times the weight of Boeing's first airplane, the 1916 B&W.
·         Seventy-five thousand engineering drawings were used to produce the first 747.
·         There are 15 models of the 747.  The newest model, the 747-400 Freighter, rolled out in February 1993 and was delivered later that year.

The 747-400 contains the greatest passenger interior volume of any commercial airliner at 31,285 cubic feet (876 m3), the equivalent of more than three 1,500-square-foot houses.
·         The 747 has 16 49-inch main landing gear tires and two nose landing gear tires.
·         The 747 has been in service since Jan. 21, 1970, carrying more than 2.2 billion passengers more than 24.7 billion miles.
·         The tail height of a 747, at 63 feet 8 inches (19.41 m), is equivalent to that of a six-story building.
·         The Wright Brothers’ first flight at Kitty Hawk could have been performed within the 150-foot (45-m) economy section of a 747-400.
·         Engine thrust on the 747-400 has grown from 43,500 (19,730 kg) to approximately 60,600 pounds (27,490 kg) per new generation engine. By comparison, total takeoff thrust of the four-engine 707-120 was 54,000 pounds (24,300 kg).
·         The first 747 had a design range of 5,290 miles (8,510 km).  The 747-400 has a design range of 8,290 miles (13,340 km).
·         The 747-400 consumes 8 percent to 13 percent less fuel than the 747-300, depending on engine selection.  This is an improvement of up to 17 percent over the first 747s.
·         The difference between the maximum takeoff gross weight (MTOGW) of the first 747 and the -400 is 165,000 pounds (78,840 kg). This is more than the MTOGW of the Boeing 737-400.
·         There are 365 lights, gauges and switches in the 747-400 flight deck, down from 971 on earlier 747 models.  That's fewer indicators for a four-engine airplane than on some twin-engine jets.
·         The United States Air Force purchased 2 specially modified Boeing 747-200Bs for the official use of the President, the first Air Force Ones were Boeing 707s and were replaced in 1989 with the delivery of the 747s.
·         The 747-400 can carry more than 57,000 gallons (215,745 L) of fuel.  This makes it possible for the airplane to fly extremely long routes, such as between San Francisco and Sydney.

The 3,300 gallons (12,490 L) of fuel carried in a tank in the horizontal stabilizer (tail) can take the 747-400 an extra 400 miles.
·         How much weight does an additional 6-foot (1.8 m) wingtip extension and winglets 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 wingtip extension and winglet.
·         Redesigned “flexible” cabin interiors not only improve passenger conveniences and appeal, but allow airlines to rearrange seats and class configuration overnight (in eight hours).  They also permit 48-hour conversion times for changes in galley and lavatory locations.
·         According to one 747 operator, no less than 5.5 tons of food supplies and more than 50,000 in-flight service items are needed on a typical international flight.
·         Engine noise from today’s 747-400 is half what it was on the original airplanes delivered in 1970.
