Admin history
  • Born in 1915, Jack Plymen served in World War II as a Scientific Officer with one of the operational research sections attached to the Royal Air Force's 2nd Tactical Air Force. The Operational Research Section was formed in 1938 to assist the RAF with problems in the operation of a chain of radar stations, and it was to liaise with the Headquarters of Fighter Command who published its reports and helped to filter its results down to the pilots. From 1941 the Section was engaged in an analysis of fighter combat tactics and conditions from the study of thousands of films recorded in combat by a cine-camera synchronized with the guns. For each clear film the ORS assessors produced a report informing the pilot of the accuracy of the attack and what, if any, damage had been inflicted. Plymen played a central role in this work and worked on a report on the gyroscopic gun-sight, published in February 1946. Similar work was carried out on the RAF's rocket projectiles and the ORS officers were able to advise on the tactics for their effective use. Plymen retired from the ORS at the end of 1945 and resumed his actuarial work for the Atlas Assurance Company Ltd., London, in January 1946. He retained his links with OR and was an active member of the Society until as recently as 1996.
