Donald Ernest Kingaby, DSO, AFC, DFM & Two Bars (7 January 1920 – 31 December 1990) was a Royal Air Force (RAF) aviator and flying ace of the Second World War.

During the initial stages of the Battle of Britain he damaged two Junkers Ju 88 bombers and a Bf 110 fighter before being transferred to No.

On 20 January 1943 Kingaby shot down Unteroffizier Helmut Peters of 6 Staffel Jagdgeschwader 26 (JG 26), who was killed in action.

After a rest period at Fighter Command HQ he was back as a wing leader in the summer of 1944 over the invasion beaches of France.

[2] An acting wing commander at the war's end, Kingaby was awarded the Distinguished Flying Cross from the United States Government on 15 May 1945,[10] and the Croix de guerre from Belgium on 15 June.

[11] After the war, Kingaby was granted a permanent commission as a flight lieutenant in the RAF on 29 November 1946,[12] with seniority from 1 September 1945,[13] but retained his war substantive rank of squadron leader until 1 January 1948,[14] then spent a year as a flight lieutenant before being promoted to the permanent rank of squadron leader on 1 January 1949.

[17] Kingaby subsequently moved to the United States, where he resided until his death in Massachusetts on New Year's Eve 1990.

Flight Sergeant Kingaby has at all times displayed the greatest determination and sound judgment, combined with a high standard of operational efficiency.

Much of the success achieved can be attributed to Squadron Leader Kingaby's great skill and inspiring leadership.
