Jan and Marion Dietrich were identical twins, 34 years old when they received notification from the Lovelace Clinic that they had passed the screening tests for astronaut training. They graduated together from the University of California, Berkley in 1949. Jan became a flight instructor and chief pilot for a flight school and corporate pilot for a construction company in California. By 1961 she had amassed 8,000 flight hours and was one of the first women in the US to obtain an Airline Transport Pilot License. One of the group of women who went to the Lovelace Clinic in Albuquerque, New Mexico in 1961 and underwent the same medical and psychological tests that the Mercury 7 astronauts had completed. She was one of the Mercury 13 finalists, considered qualified by Dr. Lovelace for astronaut training. By the year 2000 she was in poor health but had survived her twin sister by 26 years.
Birth Place: San Francisco, California.
Oddly enough, the selection of these women may have resulted in the first woman going into space after all. In May 1962 a Soviet delegation, including cosmonaut Gherman Titov and cosmonaut commander Nikolai Kamanin, visited Washington. Kamanin had been pushing for the flight of a Soviet woman into space since October 1961, and five Soviet female cosmonauts had just reported for training a month earlier. However the flight of a woman in space had little support from Chief Designer Korolev or Kamanin's military commanders. On May 3 Kamanin and Titov were invited to a barbecue at the home of astronaut John Glenn. Glenn, already politically-connected, was an enthusiastic supporter of the 'Lovelace 13'. Kamanin understood from Glenn that the first American woman would make a three-orbit Mercury flight by the end of 1962. Armed with the threat that 'the Americans will beat us', Kamanin was able to obtain a decision to go ahead with the first flight of a Soviet woman within weeks of his return. The Russians were obsessed with being first in space -- and even though NASA's female cosmonauts never materialised, Valentina Tereshkova of the Soviet Union became the first woman in space on June 16, 1963.
