Amongst many unfamiliar and strange aircraft are the Parnall Peto, intended for use on submarines, the Saro Lerwick which turned out to be such a military failure and a bizarre scheme for Sunderland flying boats to carry midget submarines. Coupled with details of those seaplanes which did much to counter the U-boat menace in World War II, more than 300 mostly previously unpublished photos, artworks, and tables, there is much for even the most demanding aviation enthusiast to savor.
