How did the Wright Brothers document their experiments and findings?

The Wright Brothers documented their experiments and findings primarily through letters, photographs, and detailed notes. This meticulous documentation was crucial for tracking their progress and understanding the principles of flight they were discovering. The brothers kept detailed records of their experiences, including flight distances, wind conditions, and technical observations, which helped them refine their designs and understand how to achieve controlled flight. Their correspondence also included letters exchanged with other engineers and inventors, which provided additional insights and feedback. The photographs served not only as visual records of their experiments but also showcased their technological advancements to the world. This comprehensive approach to documentation laid the groundwork for aviation research and development in the years to come.
