Boing 747 wingspan and the wright brothers


The Boeing 747 truly represents the current peak of passenger aircraft development. At 150 feet, the 747's economy section alone is longer than the Wright Brothers' first flight at Kitty Hawk. It is the largest passenger jet currently in service, seating up to 524 people. With a width of over 19 feet, the 747 appears from inside the cabin to be enclosed by nearly vertical fuselage walls. The plane can stay aloft for 17-hour flights, storing fuel in the tail structure as well as in the wings and fuselage. With a range of 8,430 statute miles, the 747 can easily connect such far-flung cities as Los Angeles-to-Hong Kong, San Francisco-to-Sydney and Singapore-to-London.
