This incredible work is well illustrated with drawings and photographs and provides a historical background for developing the airplane diesel engine. Moreover, it includes a technical description that provides specifications and details of the performance. In addition, it contains comments from men and women who flew planes powered by the Packard diesel. The author finishes with an analysis of the engine's advantages and disadvantages.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

"Readers are brought from commercial air transport's very beginnings to the zenith of what is fondly referred to as flying in the "Golden Age of Air Transport," when jetliners were still on the drawing board or in early production, and still a dream to come for passengers and crew."--Provided by publisher.
