Short Mayo Composite
The Short Mayo Composite was a piggy-back long-range seaplane and flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to North America and, potentially, to other distant places in the British Empire and the Commonwealth. == Development == Short Brothers had built the Empire flying boats which were capable of operating long range routes in the British Empire but could only attempt the trans-Atlantic route by replacing passenger and mail-carrying space with extra fuel.
