Bristol Type 143

The Bristol Type 143 was a British twin engine monoplane designed by Frank Barnwell of the Bristol Aeroplane Company, developed alongside the Type 142 that became the Blenheim light bomber. It used the same wing design and the same advanced features for the day, stressed skin, flaps and retractable undercarriage. It arose from the unbuilt Type 135 proposal for a civil twin engine light transport, a six passenger low wing monoplane, with the cabin enlarged to eight seats. The engines it was designed to use never entered production, it first flew on 20 January 1936 bearing the mark R 14, and only a single prototype was manufactured.
