David Hollis Williams FRAeS (18 February 1900 – 2 April 1974) was a British aircraft designer in the early 1930s for the Fairey Aviation Company, later working for Westland Aircraft. Early life He was born in Islington. Career Royal Air Force He became a pilot officer in the Royal Air Force in November 1923; he flew with the RAF from 1923. He had previously flown as a pilot from 1917 to 1919. Hawker In the mid-1920s he worked for Hawker Aircraft in north-east Surrey. Fairey He became chief designer of Fairey in 1930, succeeding Panida Antoni Ralli. In March 1933, he was awarded the Silver Medal of the Royal Aeronautical Society, for work on long range aircraft, when he was assistant chief designer; Sir Roy Fedden received the same honour. In 1938 he became a Fellow of the Royal Aeronautical Society. At Fairey he was largely responsible for the Fairey Long-range Monoplane. He rejoined Fairey in 1943 as chief engineer. General Aircraft He worked for General Aircraft Limited for nine years as chief engineer from 1934 to 1943, working with Frederick Crocombe, the company's chief designer. Together they designed the ST18 Monospar named 'Croydon' which undertook a record attempt from England to Australia, piloted by Harold 'Tim' Wood. The aircraft suffered a damaged the tail wheel in Karachi enroute and after time spent repairing the wheel they made it to Australia but without breaking the flight time. While there they won the Victoria Air Race. On the return flight the aircraft became lost due to compass problems and bad directional bearings from Darwin and had to make an emergency landing on the Serringapatam reef in the East Timor sea. All 4 crew survived after being picked up by a local fishing boat and returned to England, however the aircraft was submerged by the incoming tide and lost. There are still some remains of the aeroplane on the reef to this day. Westland Aircraft He joined Westland Aircraft in August 1951 as chief engineer, being appointed technical director in 1952. In 1960 he became assistant managing director of Westland. He retired from Westland Aircraft in 1962.

Percival Shunker had been appointed as chief designer of Westland in 1955. Personal
