The Bristol Type 143 was a British twin-engined monoplane aircraft designed by Frank Barnwell of the Bristol Aeroplane Company, with advanced features for its time: (stressed skin, flaps, and retractable undercarriage).

Design and development

Like the better-known Type 142 (built for Lord Rothermere, the owner of the Daily Mail, as "Britain First"), the Type 143 arose from the unbuilt Bristol Type 135 design for a civil twin-engine cabin monoplane.

Fitted with the new sleeve-valved and smaller diameter Bristol Aquila radial engines, the Type 143 was expected to offer some performance advantages over the Bristol Mercury-engined Type 142 (for example, allowing 8 passengers rather than the 6 of the Type 142). Only one example was built.
