variants with their own articles =Handley Page Hyderabad The Handley Page W8, W9 and W10 were British two and three-engined medium-range biplane airliners designed and built byHandley Page .The W8 (also known as the H.P.18) was the company's first civil transport aircraft. It housed two crew in an open
cockpit and a cabin for 15 passengers. Powered by twoNapier Lion 450 hp engines the prototype first flew on4 December 1919, shortly after is was displayed at the 1919Paris Air Show atLe Bourget . It has the doubtful distinction of being the world's first airliner to be designed with an on-board lavatory. The W8 was subsequently revised to give the W8b, W8e (H.P.26), W9 (H.P.27) and W10 (H.P.30)Developments
W8b
To meet an Air Ministry ruling the capacity was reduced to 12 passengers and the fuel tanks were moved. In 1921 the
Air Ministry ordered 3 aircraft for use byHandley Page Transport . These were built as the W8b and powered by theRolls Royce Eagle IX and operated byImperial Airways on services toParis andBrussels . One other aircraft was delivered toSABENA in 1924 and three others were licensed built bySABCA inBelgium .W8e
To reduce the risks involved with engine failure the W8e was developed with one 360 hp
Rolls Royce Eagle IX in the nose and two 240 hpSiddeley Puma s in the normal position. The first W8e was sold toSABENA who had ten others built in Belgium bySABCA .W8f and W8g Hamilton
One three-engined W8f was built with cabin heating (using air from the engine exhausts).
The W8f was modified in 1929 as the W8g with improved tail and rudder design from the W10 and the third engine was removed and the other two replaced with the Rolls Royce Eagle IX.
W9a Hampstead
Was a three-engined version with more powerful 385 hp
Armstrong Siddeley Jaguar IVradial engine s. It was operated byImperial Airways and created a record on the London-Paris route of 86 minutes. In 1926 the engines were replaced by three 420 hpBristol Jupiter s. The aircraft moved toAustralia but was destroyed by an accident after nine months.W10
A twin-engined variant with the 450 hp
Napier Lion for Imperial Airways (four built).Other variants

* W.8 : Prototype.
* W.8c : 1923 version fitted with two Rolls-Royce Eagle IX piston engines.Use
When Imperial Airways introduced the
Handley Page HP.42 in 1931 the W series aircraft were retired. Aircraft were used by private operators for display and joy riding, but the most important development concerned the two surviving W10s which were converted totanker aircraft by SirAlan Cobham .Operators
