Astronauts, 03/01/68: Press conference with members of NASA Group 6, the sixth group of astronauts selected by NASA in August 1967. All were scientists with no prior piloting experience. At the far left is Deke Slayton, Mercury Seven astronaut and director of Flight Crew Operations. To the right of Slayton are nine of the 11 members of NASA Group 6. They are Anthony Llewellyn, Brian O'Leary, Robert Parker, William Thornton, Philip Chapman, William Lenoir, Anthony England, Karl Heinze, and Joseph Allen. Not pictured are Donald Holmquest and Story Musgrave. Group 6 was nicknamed the "Excess Eleven" because some NASA senior officials (including Slayton) deemed the group unnecessary, given the roster of active astronauts. Llewellyn and O'Leary resigned in 1968. Chapman and Holmquest left in 1972 and 1973, respectively, due to the lack of spaceflight opportunities. The remaining seven eventually flew as Mission Specialists during the Space Shuttle program.
