The First Man-Carrying Aeroplane Capable of Sustained Free Flight: Langley's Success as a Pioneer in Aviation: From the Smithsonian Report for 1914, pages 217-222, Publication 2329, 1915

"The First Man-Carrying Aeroplane Capable of Sustained Free Flight: Langley's Success as a Pioneer in Aviation" by A. F. Zahm, Ph. D. is a scientific publication written in the early 20th century. This work explores the significant contributions of Dr. Samuel Langley to the development of aviation, focusing on his innovative designs and experiments that laid the groundwork for modern aeronautics. The likely topic of the book centers on Langley’s pioneering efforts in creating a man-carrying aeroplane that was capable of sustained flight. The book discusses Langley’s extensive background in aerodynamics and his various experiments, illustrating how he developed several model aeroplanes powered by different means, including steam and gasoline. Zahm details the challenges faced by Langley, particularly highlighting the setbacks from a crucial 1903 accident that initially undermined public confidence in aviation. However, the narrative shifts to the subsequent restoration and successful flights of Langley's machine in 1914, under the supervision of Glenn H. Curtiss, underscoring its historical significance. The text emphasizes Langley’s achievements in aerodynamics and his ultimate recognition as a trailblazer in the field of aviation, showcasing the evolution of his work and its enduring impact.
