Birdflight AS THE Basis OF Aviation

Reviewed as "One of the most important books ever published." After studying how birds fly, Lilien- thal recognized the superiority of curved winged surfaces, then developed a theory of flight. He was killed in a fatal gliding accident in 1896. The Wright Brothers considered him their hero and became inspired to investigate the problem of human flight, as they invented the airplane.
