Jeffrey Kindersley Quillwas born in 1913. In 1931 he served with the R.A.F. on a short service commission. He was appointed the test pilot for Supermarine and in 1938 became the senior test pilot. He joined No 65 Squadron on the 5th of August 1940 during the Battle of Britain to see how to improve the Spitfire in combat conditions. He was a very active member of the Squadron and took part in all the sorties he could. At around 13:30hrs on the 18th of August he helped to shoot down a He 111 flown by R.Ahrens from I Gruppe of Kg 1. His orders to leave the the Squadron arrived on the 24th of August 1940 and go back to the Supermarine works. He later flew a captured Bf 109 and commented in his book (Spitfire a Test Pilots Story) that had he flown one sooner, he would not have had so much respect for them. J.K.Qill went on to help develop the Spitfire in all the marks and some jets after the war. 

Read his book, SPITFIRE A TEST PILOTS STORY it is superb. After the war he became sales manager of the British Aircraft Corporation.
