KITTY HAWK, DARE COUNTY -

In 1903, Orville and Wilbur Wright made their first powered and heavier-than-air flights in the Wright Flyer at Kitty Hawk, N.C.

The first flight, by Orville, traveled 120 feet in 12 seconds at a speed of only 6.8 miles per hour and was recorded in this famous photograph. The next two flights covered approximately 175 feet and 200 feet by Wilbur and Orville respectively.

The altitude of all the flights was about 10 feet above the ground. In the two years afterward, the brothers developed their flying machine into the first practical fixed-wing aircraft.

Ceremonies marking the 110th anniversary of the Wright brothers' first flight are scheduled for Tuesday.

The founder of Boeing is being celebrated on the anniversary of the Wright Brothers' historic flight too.

The National Park Service and the First Flight Society are leading the celebration, highlighted by the induction of William Edward Boeing, founder of the aviation company, into the group's Paul E. Garber First Flight Shrine.

Boeing started Pacific Aero Products Co. before winning a contract to build 50 planes for the Navy as the U.S. entered World War I. He changed the company's name to Boeing Airplane Co.

Louis Mancini, Boeing's senior vice president for commercial aviation services, is scheduled to give the keynote address.
