Blackburn Sydney
British flying boat
From Wikipedia, the free encyclopedia
The Blackburn R.B.2 Sydney (serial N241) was a long-range maritime patrol flying boat developed for the Royal Air Force in 1930 in response to Air Ministry Specification R.5/27. It was a parasol-winged braced monoplane with a typical flying boat configuration, featuring triple tailfins and three engines mounted on the wing's leading edge. After evaluation, it was not ordered into production, and no further examples were built.
