The Hurricane with the highest number of kills during the Battle of Britain was P3308, a Mk1, flown between 15 August and 7 October 1940 by RAF (auxiliary) pilot Archie McKellar of 605 Squadron. He is credited with 21 kills, 19 of those in a Hurricane during the Battle of Britain. On 7 October he is credited with shooting down 5 Bf 109s, making him one of only two RAF pilots (the other one was Brian Carbury of New Zealand) to become an Ace in a Day during the Battle of Britain. During his brief fighting career, McKellar earned the DSO, DFC & Bar. McKellar has remained in relative obscurity in Battle of Britain history, as he was killed in action one day after the date set by the War Ministry (after the War) as the official end date for the Battle of Britain. He was killed on 1 November 1940 while taking on a superior number of Bf 109s.
