| British Airways- Boeing 747 |
The Boeing 747 is a widebody commercial airliner and cargo transport, often referred to by the nickname Jumbo Jet or Queen of the Skies. It is among the world's most recognizable aircraft, and was the first widebody ever produced.
First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.
The 747-400 incorporates major aerodynamic improvements over earlier 747 models, including the addition of winglets to reduce drag, new avionics, a new flight deck and the latest in-flight entertainment systems. And, the 747 continues to be the world's fastest subsonic jetliner, cruising at Mach .855 -- or 85.5 percent of the speed of sound.
The four-engine 747 uses a double deck configuration for part of its length. It is available in passenger, freighter and other versions. Boeing designed the 747's hump-like upper deck to serve as a first class lounge or (as is the general rule today) extra seating, and to allow the aircraft to be easily converted to a cargo carrier by removing seats and installing a front cargo door. Boeing did so because the company expected supersonic airliners (whose development was announced in the early 1960s) to render the 747 and other subsonic airliners obsolete, while believing that the demand for subsonic cargo aircraft would be robust into the future.
Did you know the 747-400 wing measures 5,600 square feet (524.9 sq m), an area large enough to hold 45 medium-sized automobiles?
