What was the primary funding source for the Wright Brothers' aviation experiments?

The primary funding source for the Wright Brothers' aviation experiments was indeed their bicycle business profits. The Wright Brothers, Orville and Wilbur, established a successful bicycle company that enabled them to save money and finance their aviation projects without relying on external funding sources. This financial independence allowed them to experiment more freely and maintain control over their inventions. They used the revenue generated from their bicycle sales to purchase materials, build wind tunnels, and conduct flight tests, which were essential to their eventual success in developing the first powered aircraft. Their experience in the bicycle business also contributed to their understanding of balance and control in flight, which was crucial in their design and engineering process.
