U is for “Union”
as in Soviet. Women. Military. Pilots. And the combination thereof.
Once upon a time in 1942 there was a group of women in a place called the Soviet Union. They were the 588th Night Bomber Regiment. They had the “oldest, noisiest and crappiest planes in the entire world”, which makes it really easy for the enemy to hear you coming from a mile away and train anti-aircraft batteries on you.
So what did they do? They would climb to altitude and SHUT DOWN THEIR ENGINES. Then they would coast down to target, drop their load, RESTART THEIR ENGINES IN MID-FLIGHT and haul ass back home.
The scared the every loving shit out of the Germans who gave them the nickname “Die NactHexen” or “The Night Witches”.
