Saunders Roe SR.45 Princess flying boat being serviced or scrapped (minus propellers). The largest flying boat ever constructed, with ten turboprop engines driving 6 pods of propellers. 3 were ordered & built for BOAC, but only one flew. The age of the flying boat was ending when the first took to the air, in 1952. The order was cancelled and the 3 were scrapped after approaches to the RAF & USAF for their use as transports failed.
Saunders-Roe SR.53 (1957) was a British prototype interceptor aircraft of mixed jet and rocket propulsion developed for the Royal Air Force by Saunders-Roe in the early 1950s. Although its performance was promising, the need for such an aircraft was soon overtaken by surface-to-air missile development and the project was cancelled after 56 test flights.
Saunders Roe Flying Boats: SR.A/1 Jet powered flying boat, often called the squirt. This aircraft had the first Martin Baker ejector seat. It was claimed to be too slow and was canceled, but Tommy Atkins, a chase plane pilot on the project, said it was much faster than it appeared and left him standing in his Meteor.
