Joan Potts enlisted into the WAAF in 1940 and trained as a filterer before going to HQ 10 Group at Rudloe Manor near Bath where she remained throughout the Battle of Britain and during the Blitz. She worked in a team that filtered the information received from radar sites, the Royal Observer Corps, airborne aircraft and other sources in order to pass the crucial information to the plotting room where the duty commander was able to deploy his forces by reference to the updated map table. She was later commissioned and served at other control rooms. After the war she transferred to the Reserve but was recalled to the recently re- formed WRAF in 1949. She worked in Combined Operations and was appointed MBE. She died aged 102.
