Manly is a scientific publication likely written in the late 19th and early 20th centuries. This work documents the pioneering experiments in aerodynamics conducted by Langley, focusing on the practical aspects of mechanical flight, including models powered by various engines and the significant technical challenges faced in the pursuit of sustained aerial transportation. The narrative intertwines rigorous scientific inquiry with historical context, showcasing the evolution of flight technology during this formative period. The opening of the memoir introduces Langley as an early advocate for mechanical flight, recounting the essential experiments that took place from 1887 to 1896. Langley reflects on the evolution of his aerodromes, initially utilizing rubber-powered models and eventually transitioning to more powerful steam engines. He emphasizes the frustrations stemming from the limitations of earlier models, such as issues with weight and launching mechanics. The text sets the stage for a detailed recounting of his trials, including the scientific hypotheses behind design choices, the trials of constructing lighter and more efficient models, and Langley’s aspirations for a successful demonstration of sustained flight had been realized in his experiments by May 1896.
