“Collins worked hard and overcame adversity every inch of the way on her journey to space. Her family struggled to make ends meet in upstate New York, and she put herself through community college and paid for flying lessons by working full time in a variety of jobs. Collins learned to fly when she was only 19: “I didn”t spend money on clothes…I”d grown up watching gliders fly off Harris Hill (in Elmira, New York) and I”d always dreamed of flying.” She graduated from Syracuse University with a bachelor’s in mathematics and economics, and obtained a master’s in operations research from Stanford University in 1986. She also holds a master’s in space systems management from Webster University. From 1986 to 1989, Collins was a math instructor at the Air Force Academy. During that time, she was also a test pilot at Edwards Air Force base, flying 26 different aircraft in a single year.” National Womens Hall of Fame
