They flew under the cover of darkness in bare-bones plywood biplanes. Their planes were too small to show up on radar. Radio locators were useless as the female-flying Soviet squadrons never used radios on their after-dark missions. Their bomb runs were so deadly accurate that the Nazi soldiers were terrified to the point of being afraid to light a cigarette for fear of giving away their position. They braved bullets and frostbite in the air… and skepticism and sexual harassment on the ground. From pilot, to mechanic, to officer, every one… female. They flew silently, with the only hint of their approach being the soft whooshing sound their cheaply constructed wooden planes made in the wind, a sound resembling that of a sweeping broom, thus the Germans gave them the nickname “Nachthexen”. The “Night Witches”.
