The Saunders A.4 Medina was a British flying boat built by S.E. Saunders at East Cowes, Isle of Wight.
The Medina was built for the Air Council between 1925 and 1926 and was a plywood-covered wooden flying boat powered by two 450 hp Bristol Jupiter VI radial engines mounted onto and slung from the top wings.[1] The upper wing was slightly smaller than the lower wing, braced with Warren truss-type interplane struts.[2] It had a crew of two and room for ten passengers. Only one Medina was built, registered G-EBMG, first flying in November 1926. It proved disappointing, having poor water handling, with its hull being prone to leaks.[3] It was withdrawn from use and scrapped in 1929.
