Which country did the Wright Brothers conduct most of their flight testing?

The Wright Brothers conducted most of their flight testing in the United States, specifically in Kitty Hawk, North Carolina. This location was chosen because it offered favorable wind conditions and privacy for their experiments with powered flight. The brothers made their first successful powered flight on December 17, 1903, in this area, which marked a significant milestone in aviation history. Their testing involved not just the flights themselves but also extensive experimentation with gliders and other flying machines in the preceding years, all taking place in various locations throughout the United States. This foundation of testing and innovation led to the development of their first practical airplane, making the United States the central hub for their groundbreaking work in aviation.
