The Handley Page H.P.42 was a large unequal-span sesquiplane. It incorporated numerous original features throughout its design. It had an all-metal frame with fabric covering on the wings, tail surfaces and rear fuselage. The fuselage comprises two sections, the unusually long forward section built up around massive riveted girders and partly skinned with corrugated metal, while the rear was built around welded steel tubes and skinned with fabric. Their construction was noted as being relatively expensive,
Four H.P.42 and four H.P.45 aircraft were delivered, while two of the H.P.45s were later converted into H.P.42s.
The first flight of the prototype, Hannibal, was on 14 November 1930. The aircraft was named after Hannibal, the Carthaginian military commander.
On 8 August 1931, while on a scheduled passenger flight from Croydon to Paris the port lower engine failed. Debris from the failed engine struck the port upper propeller, causing it to vibrate so severely it had to be shut down. A forced landing was made at Five Oak Green, Kent where the aircraft suffered further damage to a wing and another propeller, and the tail was ripped off by a tree stump. There were no major injuries amongst the 20 passengers and crew. The aircraft was dismantled and taken to Croydon by road for rebuild. Hannibal was again damaged at the RAF temporary landing ground at Semakh on the Sea of Galilee on 17 November 1932, by strong winds. The fuselage and heavily damaged wings were sent by 3 ft 5 in (1.05 m) gauge Hedjaz Railway to Haifa, where it was transferred to the 1.435 m (4 ft 8.5 in) standard gauge Palestine Railways and forwarded to Heliopolis for repair. It disappeared over the Gulf of Oman on 1 March 1940, with eight aboard, including the First World War ace Group Captain Harold Whistler and the Indian politician Sir A. T. Pannirselvam. An early report that wreckage of the aircraft had been located, turned out to be incorrect. No trace has ever been discovered and the cause of its loss remains unknown

Replica Several efforts have been made to produce an H.P.42 for heritage/preservation purposes. During 2015, a fundraising campaign was launched with the aim of producing a replica of the H.P.42. Original blueprints and other source material from the era are available and while a replica can be built to be airworthy, modern safety regulations prevent carrying paying passengers
In 1956, Vickers had performed a series of low level tests in WZ383 to assess the type for low level flight at high speed.
The H.P.42 was powered by four 490 hp (370 kW) Bristol Jupiter XIFs, while the H.P.45 variant used four 555 hp (414 kW) Jupiter XFBM supercharged engines
