Did you know the Avro Ava had a 29.5 m wingspan?

The Avro Type 557 Ava was a British twin-engined biplane torpedo bomber from the 1920s. It originated from Specification 16/22, issued by the British Air Ministry in 1922, which called for a long-range land-based torpedo bomber. The requirement demanded that the aircraft be able to carry a 21 in (533 mm) torpedo or an equivalent weight of bombs. Roy Chadwick, Avro's chief designer, first submitted a single-engined design, the Avro 556. It was dropped in favour of a twin-engined aircraft with two Rolls-Royce Condor engines, the Avro Type 557 Ava.

The Ava's wingspan was 96 ft 10 in (29.51 m). It was a three-bay biplane of wooden construction, with the uncowled engines mounted between the wings. The powerplant consisted of two Rolls-Royce Condor III water-cooled V-12 piston engines, each rated at 650 hp (480 kW). The fuselage housed two pilots in an open cockpit, with gun positions in the nose and dorsal, and a retractable "dustbin" ventral position that could be manned by the navigator-bomb aimer.

The first Ava prototype, serial number N171, flew in mid-1924. The Air Ministry later abandoned its plans to use that torpedo. The type was not a success, and no other aircraft were built.
