The Boeing 747, which is also known as the jumbo jet, is the second largest passenger airliner after the Airbus A380. Until the first commercial flight of the A380 in 2006, however, it remains the largest passenger aircraft in commercial service.
The four-engine 747, produced by Boeing Commercial Airplanes, uses a two-deck configuration, where the small upper deck is usually used for business-class passengers. A typical three-class layout accommodates about 400 passengers while a one-class layout accommodates a maximum of 600 passengers. The hump created by the upper deck has made the 747 a highly recognizable icon of air travel.
The 747 flies at high-subsonic speeds (typically 0.85 Mach or 565 mph or 909 km/h) and features intercontinental range (8,430 statute miles, or 13,570 km, for the 747-400 version), in some configurations sufficient to fly from New York to Hong Kong (roughly a third of the globe) non-stop. In 1989 a Qantas 747-400 flew non-stop from London to Sydney, a distance of 11,185 miles (18,000 km), in 20 h 9 min, although this was a delivery flight with no passengers or freight aboard.
...
The development of the 747 was a huge undertaking. Boeing did not have a factory large enough to assemble the giant aircraft, so the company built an all-new assembly building near Everett, Washington. This factory is the largest building ever built.
...
A 747-400 has six million parts (half of which are fasteners) made in 33 different countries.
Due to its immense length, there is a very small flexure of the fuselage in flight. This effect was not anticipated in the design of the autopilot on early models, and so there is a very slow oscillation in yaw when flying on autopilot. This was first discovered on an overseas flight to the Paris Airshow, when some of the people in the rear got air sick. Upon return, the plane went through a shake test for two weeks to sort out the problem and adjust the yaw damper system. This solved the problem and the effect is now too small to be noticeable by passengers.
