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] 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.
