Cox hasn't used prosthetic arms since she was 14. She can use her feet like most people use their hands to type, put in and take out contact lenses, or drive a car, not to mention other complicated tasks that most people with full use of all their limbs never even attempt.
When Cox was 14, taekwondo instructor Jim Cunningham assured her that she could compete in the martial art if she wanted to. With his encouragement, Cox went on to earn her first black belt. She continued her training during college, becoming the first armless person to earn a black belt in the American Taekwondo Association.
Cox's most famous accomplishment has been learning to fly planes. It took some determination to find the right plane she could maneuver successfully using her feet, but once she came across the Ercoupe, it was smooth sailing (or flying). Cox earned her pilot's license on Oct. 10, 2008, along with the Guinness World Record for being the first person certified to fly an airplane using only feet.
When Karlyn Pranke was told her daughter would be born without arms, she researched Cox's story. She knew she had to help her little girl, Ruth Evelyn, aka R.E., grow up believing that she could accomplish whatever she wanted.
RE had been struggling with feeling different and frustrated at her limitations, but once she met Cox, she realized that nothing is impossible. She was excited to meet someone who looked like her and who could still do all sorts of things. The Prankes keep in touch with Cox, reporting R.E.'s progress and learning more and more from her role model.
