On their first day of astronaut training, this second group of scientist astronauts were told they were surplus to requirements, due to cut backs and changes in the launch manifest. As a result, they became known as The Excess Eleven (XS-11). None had previous military jet pilot training so all had to participate in year long USAF jet pilot coiurse. Some of the group had great difficulty in adapting to jet pilot training and detachment from their scientific research time and the requirement of total commitment to astronaut training. Don Holmquest, Phil Chapman, Brian O’Leary and John Llewellyn, all left without making a space flight, whilst the others had to wait years to make a shuttle mission. Story Musgrave would remained at NASA completing six shuttle missions between 1983 and 1996. He became the only person to fly on each of the Orbiters (flying Challenger twice) and left NASA in 1997 after 30 years service. Bob Parker became the last original member of the scientist astronauts (of those selected in 1965 and 1967) to leave NASA in 2005 though he had complete his second and final space mission in 1990.
