Final answer:
Information on wing walkers and brake riders can be found in historical aviation texts, aviation museums, and military archives. Wing walkers performed stunts on aircraft wings, and brake riders helped in braking heavy artillery. Books, museums, and reputable online resources are good places to begin your research.
Step-by-step explanation:
Information about wing walkers or brake riders can generally be found in historical texts, documents on early aviation history, and in museums dedicated to aviation. Wing walkers were daredevil stunt performers who would walk along the wings of an airplane, typically during airshows, in the early days of aviation when planes flew at much lower speeds than today. Brake riders, on the other hand, were individuals who sat on the brakes of large railroad guns or heavy artillery to assist with the braking process when the pieces needed to be moved.
To learn more about wing walkers or break riders, a good starting point might be books on the history of aviation or military equipment, respectively. Visiting aviation museums or historical military sites may also offer more hands-on or visual information. Finally, reputable online aviation history resources or military archives could provide detailed accounts and photographs of wing walkers and brake riders.
