What Day Was the Wright brothers' first powered flight?

About this date

Orville and Wilbur Wright achieved the first sustained, controlled, powered flight of a heavier-than-air aircraft at Kitty Hawk, North Carolina, with Orville piloting the Wright Flyer for 12 seconds over 120 feet.

The brothers made three more flights that same day, the longest covering 852 feet in 59 seconds, laying the foundation for the aviation industry that followed.

The brothers had spent the previous several years testing gliders at the same windy North Carolina site specifically because of its consistent, predictable wind conditions, an important variable for early powered-flight experiments.

The Wright brothers had earlier applied engineering rigor unusual for the era, building their own wind tunnel to test wing designs systematically rather than relying purely on trial and error like many contemporary aviation pioneers.
