December 17 should be a day of celebration, and some might argue that’s thanks to those involved in the aviation world. Many historic milestones were reached on this day, starting with the Wright brothers’ first successful powered flight.

Orville and Wilbur Wright, bicycle mechanics from Ohio, had been experimenting with kites and then gliders for years. On December 17, 1903, the propellers on the Wright Flyer turned, powered by a 4-cycle 12 hp engine, and the aircraft took off from a track and flew for “12 seconds that changed the world.”
