Squadron Leader David John Hatfeild Maltby, (10 May 1920 – 15 September 1943) was a bomber pilot in the Royal Air Force, best known for his part as the pilot of Lancaster AJ-J (“Johnny”) in the Dambusters raid. He had successfully completed over 30 operations before his death in September 1943.
Early life
Maltby was born on 10 May 1920 in Baldslow, outside Hastings, Sussex. His father, Ettrick, was a headmaster at Hydneye House School which Maltby attended for a while. His mother was Aileen Hatfeild, who was originally from Hartsdown in Kent. He then joined Marlborough College between 1934 and 1936. In 1938 he began training as a mining engineer in Treeton, South Yorkshire, but resigned at the outbreak of war. He volunteered to join the Royal Air Force (RAF) in 1939 however like thousands of others joining, he was told to wait and that he would be invited back for an assessment as soon as possible. He was eventually called up on 20 June 1940 where he was accepted for aircrew training and formally joined the RAF Reserves.
Maltby's maternal uncle was the First World War Royal Flying Corps pilot Aubrey Hatfeild MBE. His great grandfather was Brough Maltby the Archdeacon of Nottingham.
RAF career
Training
Maltby started training at the RAF receiving unit in Uxbridge on Thursday 20 June. After spending some time in the Initial training wing, he attended the Elementary Flying Training School at Ansty in Warwickshire. Here, he trained in an old training aircraft known as the "Tiger Moth". After this, he was sent to No 12 Service Flying Training School at RAF Grantham. He qualified as a pilot on 18 January 1941.
Operational career
Maltby began his operational career with No. 106 Squadron RAF in June 1941, flying the Handley Page Hampden on five operations. By the end of the month he was transferred to 97 Squadron, flying first Hampdens, then Avro Manchesters and finally Avro Lancasters.
On 4 May 1942 whilst on a mission to Struttgart, Maltby and his crew had taken heavy fire shortly after hitting enemy coast. They were carrying a large bomb load and due to the damage they had sustained they were unable to open the bomb doors to jettison the bombs. As well as this, the landing gears could not be properly deployed as they would not lock in place. Maltby made the decision to head back to base at Woodhall Spa but was directed to land at Coningsby instead due to it being a grass runway. Sgt Harold Rouse, who was at the time a gunner on Maltby's crew recalls the incident:
All crew miraculously were unscathed after the incident.
He went on to complete his tour in June 1942, and was awarded the Distinguished Flying Cross on 11 August 1942.
Maltby then spent six months commanding an Air Bomber Training Section in No. 1485 Target Towing and Gunnery Flight, before returning to active service with 97 Squadron in March 1943. He was given a new crew, most of whom had only just finished training. On 25 March 1943, he and his crew were transferred to 617 Squadron, along with Flt Lt Joe McCarthy and Flt Lt Les Munro and their crews.
Operation Chastise
Maltby flew in the No. 617 Squadron RAF Operation Chastise dams raid of 1943. He was the pilot of Avro Lancaster J-Johnny, flying as part of the first wave that attacked the Möhne Dam. The first three aircraft to attack the dam (Guy Gibson flying in G-George, Hopgood in M-Mother and Harold Brownlow Martin in P-Popsie) all missed the target. The next, A-Apple (flown by Dinghy Young) hit the dam and caused a small breach but, as this was not apparent from the air, J-Johnny also attacked, scored a hit and a large breach. Maltby then returned home and was the first Lancaster to land back at Scampton having completed the operation.
For his part in Operation Chastise, Maltby was awarded a Distinguished Service Order. He was shortly after promoted to Squadron Leader and appointed as A flight commander of No. 617 Squadron.
During Gibson's leave from June until August Maltby became the acting Commanding Officer for 617 squadron until George Holden was appointed as the new permanent replacement for Gibson.
