Pilot Kevin Kochersberger rides the Experimental Aviation Association's (EAA) 1903 Wright flyer reproduction down the 180 foot rail in his first attempt to reenact the "12 seconds that changed the world" during the Centennial of Flight celebration at Kitty Hawk, North Carolina (NC), December 17, 2003. The prevailing winds that brought the brothers to Kitty Hawk for their flight experiments weren't on hand at the Centennial of flight celebration. Despite two attempts between storm fronts the EAA crew was only able to get their 1903 Wright flyer reproduction about six inches off its rail before crashing at the end before a crowd of some 34,000 aviation enthusiasts
