Princess Eugenie was the cousin of Russian Czar Nicholas II, and they’d go on to have one of the illest family squabbles. She had the $$$, so she funded her own flying lessons and started doing reconnaissance missions for cousin Nick, but he ended up charging her with treason and sentencing her to death! She was freed during the Russian revolution, only to become addicted to drugs. Eugenie ended up getting shot in a narcotic-induced gunfight with some colleagues, like the badass with questionable decision-making skills she was. RIP, lady.
