This is a big beautiful book about the glamorous seaplanes that flew the oceans. The illustrations are excellent. However, the text contains many errors. For example: the aircooled Bristol Jupiter engine is listed as watercooled, Martin and Osa Johnson had one S-39 and one S-38, not two S-38's, the Sikorsky S-42 was not designed to be appreciably larger than the S-40, the S-42 was designed with much lower drag so that it could go faster and farther. While a matter of opinion, the choice of planes did not include the Aeromarine Curtis 75, the first Flying Boat in regular America-Overseas service, nor the VS-44, that joined the Boeing 314 Clippers in providing flying service between Europe and America early in WW11. Also it would have been nice to have some illustrations of the later Latecoere's, not just the early 300 model.
