under control, and was one of many that the women of the Mercury 13 went through in order to qualify for space flight. Although Cobb successfully completed all three stages of physical and psychological evaluation that were used in choosing the first seven Mercury astronauts, it was not an official
NASA program, and she was unable to rally support in Congress for adding women to the astronaut program. At the time, Cobb had flown 64 types of
propeller aircraft, but had made only one flight in a
jet fighter, in the back seat. Astronaut
John Glenn stated at the hearing that "men go off and fight the wars and fly the airplanes", and "the fact that women are not in this field is a fact of our social order". Only a few months later, the
Soviet Union sent the first woman into space, Along with other Mercury 13 participants, including
Jane Briggs Hart, Cobb lobbied to be allowed to train alongside the men. At the time, however, NASA requirements for entry into the astronaut program were that the applicant be a military test pilot, experienced at high-speed military test flying, and have an engineering background, enabling them to take over controls in the event it became necessary. Since all military test pilots were men at the time, that effectively excluded women. Liz Carpenter, the executive assistant to Vice President
Lyndon B. Johnson, drafted a letter to NASA administrator,
James E. Webb, questioning those requirements, but Johnson did not send the letter, instead writing across it: "Let's stop this now!" == Later life and death ==
