Geoffrey Wellum was a young fighter pilot who joined his Squadron, no. 92, flying Spitfires in May 1940. The squadron was initially based at Northolt, but moved to Biggin Hill during the Battle. The remarkable thing about Wellum was his youth. His nickname was “Boy” because of it. He had joined the RAF at the end of July1939, only weeks before the war began. He had timed his entry to coincide with the end of the cricket season in the last summer of peace.

He was credited with several kills and received the DFC in 1941. Interspersed with several rest periods, he spent three years flying Spitfires after the Battle. First, these involved flying in fighter sweeps over northern France, then a period at Malta flying there. He, subsequently, became a test pilot helping with the development of the Typhoon.

He wrote a memoir, First Light,of his experiences in the RAF, from which he retired in 1961. The book was published by Penguin and became a great success. It contains the most illuminating description of the RAF in 1939 and 1940, from training as a pilot to service on a squadron. It is a ‘must’read.
