[[Donald K. Slayton]] did not fly a Mercury mission. The flight surgeons grounded him for nearly a decade and a half after finding that he suffered from an occasional dysrhythmia of the [[heart]]. The other six astronauts then recommended to NASA administration that the astronaut corps should have a permanent chief, chosen among their number, and chose Slayton to fill that position. Slayton was the only chief that the astronaut corps ever had. He would finally fly the [[Apollo-Soyuz Test Project]] mission in 1975, the last mission flown with [[Project Apollo]] hardware.
