"The first anaesthetic in childbirth On 19 January 1847, the Edinburgh obstetrician, James Young Simpson (1811-1870), delivered the first child born to a mother anaesthetised with chloroform (half a teaspoon on a rag applied to the nose). The child was named Anaesthesia. It was so successful that, within a week, he had given it to 30 mothers. There followed many protests from those who believed that women were intended to 'bring forth children in sorrow.'"
Nightwitches - Female Russian bombers who bombed Germany during WW2. They had old, noisy planes & the engines used to conk out halfway through their missions, so they had to climb out on the wings mid-flight to restart the props. To stop Germans from hearing them & starting up the anti aircraft guns, they’d climb to a certain height, coast down to German positions, drop their bombs, restart their engines in midair & get the hell out of dodge. Their leader flew 200+ missions & was never captured.
