Boeing 747 Flies for First Time By Marcel Brown | 1 January 12, 1970 The Boeing 747, the original “Jumbo Jet”, makes its maiden flight. The 747 was the first wide-body airliner, first to use the twin-aisle concept, and the first airliner to use high bypass turbofan engines. Posted in Miscellaneous Technology Scot_Kroozr If you wish to see the original ‘City of Everett’, come to the Museum of Flight in Seattle. It’s looking worn and shabby now in the overflow parking lot, but is STILL a very impressive piece of aeronautical engineering. Your admission fee will help fund the new building that will eventually bring the plane indoors, where it will be be spiffed up again.
