History

The Boeing 747 first flew on 9th February 1969. (The very first plane, called the City of Everett after the place where it was built, is now kept in the Museum of Flight in Seattle, USA.) Just under a year later, on 21st January 1970, a 747 took off from New York bound for London with the first fare-paying passengers aboard. By July of that year, a million people had travelled in a Jumbo Jet. 

A later version of the Jumbo, the Boeing 747-400, looked similar to the original 747 on the outside, but inside, new technology made it almost a completely different aeroplane. For example, on the flight deck of the original version, there were 971 lights, dials and gauges; they numbered only 365 on the 747-400. The engines were 50% more powerful—and only half as noisy.
