Design and development

[edit]

The Type 179 was an all-metal monoplane flying-boat powered by six Rolls-Royce Buzzard piston engines mounted above the wing.[1] It was to have a crew of seven and room for 40 passengers in a day configuration.[1] The keel was laid down in 1931 and the aircraft was under construction when the project was abandoned in 1932. The aircraft had been registered G-ABLE in April 1931.[1]
