Patricia "Patty" Doyle (died c. 1970) was an astronaut candidate for NASA and former Mercury 13th pilot. Patty was top of the Astronaut candidate class along with Molly Cobb, both being part of the aborted Mercury 13 project. Unfortunately, she crashed her module during LEM simulations and died in the process.
Patty is noted as being one of only two women who passed the Mercury 13 training program who still flies aircraft, and for being selected for the female Apollo program. She is also noted to be an experienced helicopter pilot. Like the training module she died in, the helicopter is a vtol (vertical takeoff and landing) capable aircraft.
Patty is also notable for placing second in almost all of her astronaut candidacy training tests.
