Saro London and Lerwick

The Saro A.27 London was one of the last generation of large biplane flying planes to serve in the RAF, operating alongside the Supermarine Stranraer in Coastal Command in the years immediately before the Second World War.
The Saro Lerwick flying boat was one of the least successful aircraft to serve with the RAF during the Second World War, and demonstrated the danger of ordering a new design off the drawing board.
