In the US and the UK, members of the WAAC (Women’s Army Auxiliary Corps) and the WAAF (Women’s Auxiliary Air Force) numbered in the tens of thousands, where they served as switchboard operators, air traffic controllers, and deployed barrage balloons. They occasionally got close to combat, the UK’s Flying Nightingales who served as air-ambulance nurses, first flew into Normandy just a week after D-Day to evacuate servicemembers injured during the initial assault. Both countries also employed many female aviators as training and cargo pilots, but they were almost all civilian employees of the armed forces unlike members of the WAAC and WAAF.
