The Airco DH.6 was a military trainer biplane used by Britain's Royal Flying Corps during World War I. It was of conventional configuration with unstaggered, two-bay wings and a tractor-mounted engine driving a four-bladed propeller. The pilot and instructor sat in tandem in a single open cockpit. One unusual feature of the design was its long exhaust stacks that rose vertically from the engine installation and ended above the upper wing, a characteristic that earned the type the nickname "sky hook". Other nicknames for the type included "crab", "clockwork mouse", "flying coffin" and "dung hunter" (these last two on account of the shape of the plywood cockpit - thought to resemble either a coffin or an outside toilet).
Designed as a trainer, the DH.6 had very gentle flying characteristics, almost impossible to stall or spin. Nevertheless, intended to prepare pilots for fighter aircraft, it was designed to be intentionally unstable, earning it yet another nickname, "clutching hand".
The DH.6 was soon rendered obsolete by the Avro 504 but nevertheless, over 1,000 were still in service with the RFC and RNAS at the time of the Armistice. Many of these found their way into civillian hands after the war. Some were exported as far as South Africa and Australia, where they could be found flying into the late 1930s.
