Formed in 1912, Lockheed Aircraft Corporation was a leading WWII aircraft manufacturer and was responsible for the only plane in production throughout the entire war, the P-38 Lightning. Lockheed's Chief Engineer, Hall L. Hibbard, states the book's intention in the Preface: "to give the designer a collection of ideas, in sketch form, that will stimulate his own creative and inventive mind." Model builders, vintage aircraft enthusiasts, and any creative person with an interest in the field will find this volume a valuable resource.
