Night Witches.

Some more cool facts about the Night Witches.
* The regiment was made up entirely of women volunteers in their late teens and early twenties.
* Due to the weight of the bombs and the low altitude of flight, the pilots carried no parachutes.
*An attack technique of the night bombers was to idle the engine near the target and glide to the bomb release point, with only wind noise left to reveal their location. German soldiers likened the sound to broomsticks and named the pilots "Night Witches."
* It was the most highly decorated all-women unit in the Soviet Air Force, each pilot having flown over 800 missions by the end of the war and twenty-three having been awarded the Hero of the Soviet Union title.
