"The Saunders-Roe SR.45 Princess was a British flying boat aircraft built by Saunders-Roe, based in Cowes on the Isle of Wight. The Princess was the largest all-metal flying boat ever constructed.The project was cancelled after having produced three examples, only one of which flew. By the mid-1950s, large, commercial flying boats were being overshadowed by land-based jet aircraft."@en . . "3"^^ . .
