Beryl Rettinger (nee Pashley), Beryl was a British RAF WAAF during the air battles over the English Channel after the Battle of Britain and sat in a very small cone-roofed building on the English coast and rotated an antenna by hand on a pole that went through the roof using something like a steering wheel or horizontal bicycle tire. She listened to the Spitfire cockpit radios on her headset as the English and German pilots flew and fought over the channel. Her bearing on the radio signal along with two others elsewhere allowed Air-Sea rescue to triangulate where the combat was taking place over the water and the position of the pilots who crashed. (The sound of the pilots going down on the radio was extremely distressing.) She received an award one time when only her single bearing allowed a rescue plane to fly along the bearing and recover a pilot. She later married Thomas C. Rettinger, a US serviceman, became a "War Bride," and moved to Minnesota in 1946. 
Beryl served during WWII guiding fighter pilots back to the base after missions across the English Channel. While serving she met Tommy who was in the 8th Air Force.
