The W.8 (also known as the H.P.18) was the company's first civil transport aircraft. It housed two crew in an open cockpit and 15 passengers in an enclosed cabin. Powered by two 450 hp (336 kW) Napier Lion engines the prototype first flew on 4 December 1919, shortly after it was displayed at the 1919 Paris Air Show at Le Bourget. It has the distinction of being the world's first airliner to be designed with an on-board lavatory. The W.8 was subsequently revised to give the W.8b, W.8e (H.P.26), W.9 (H.P.27) and W.10 (H.P.30)
