Deke Slayton

SlaytonAWisconsin native Deke Slayton flew 56 combat missions in Europe during WWII, but is probably best known as one of the original Mercury 7. Though he was grounded due to a heart condition, Slayton filled a vital role well enough to fly in the early 1970s, and made his first space flight as pilot of the Apollo-Soyuz Test Project (ASTP) mission—a joint space flight between American astronauts and Soviet cosmonauts.
