Airspeed Ferry
airliner
The Airspeed AS.4 Ferry was three-engined ten-seat biplane airliner designed and built by the British aircraft manufacturer Airspeed Limited. It was the company's first powered aircraft to be produced.
It was proposed for development in April 1931, shortly following Airspeed's founding. The Ferry was designed specifically for Alan Cobham's National Aviation Day events, performing 'air-experience' flights for the general public. On 5 April 1932, the prototype performed its maiden flight. Only four examples were produced at the company's facilities in York during the early 1930s. Two aircraft served with the Royal Air Force during the opening years of the Second World War, although largely being used as instructional airframes.
Development
The origins of the Airspeed Ferry can be traced back to the company's first post-formation board meeting, held on 17 April 1931. Aviation innovator and Airspeed director Sir Alan Cobham sought a compact multi-engined airliner to perform 'air-experience' flights in Cobham's National Aviation Day displays. Amongst the requirements for such an aircraft was an extraordinary short takeoff and landing (STOL) capability for the era due to the austere airstrips common at the time, which were often little more than fields.

Why this record matters
The phrase “airliner” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 5, 2025. The linked authority identifier is Q409161. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1931 and 1932.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
