Woltman attended the St. Cloud Teacher's College after school. After a few years of teaching, she moved to Texas and started training as a pilot. Her first plane was a
Piper J-3 Cub and then she progressed from a private pilot to a commercial pilot. This earned her rating as an instructor for flying airplanes. Woltman attained her
seaplane rating for airplanes with floats and her rating as a glider pilot. She flew competitively, and she also completed one of the major flights of the era for women, a solo flight from Houston to Anchorage in a
Piper Super Cub with floats. Working as a charter pilot, Woltman flew over North America and also flew in the International Women's Air Race and in the
Powder Puff Race. In March 1961, Woltman started training as an astronaut. She cleared all physical tests and was a part of the
First Lady Astronaut Trainees (FLATs). As next steps, few from the group of 13 went to advanced testing but since the project was not officially run by
NASA, Woltman never stepped into the space. She was one of the thirteen women who passed all of the astronaut tests given at the
Lovelace Clinic in 1961, making her a member of the
Mercury 13. Woltman retired her pilot license in March 2014. In 2007, the University of Wisconsin conferred on Woltman and the remaining Mercury 13 astronauts an Honorary Doctorate in Aeronautics, honoring them as pioneers in aviation history. She was inducted in the
Colorado Women's Hall of Fame in 2008. == After Mercury 13 ==
