Dyna Soar 19 Spacecraft: (no serial number) Launch Vehicle: Titan II/Centaur Scheduled Launch: 1 Dec 1967 Last Scheduled: 14 Sep 1961	⇑ Mission List ⇑ Designation: Dyna-Soar T2C O-2 Description: 2nd Dyna-Soar Titan II/Centaur manned orbital
	not assigned Backup Crew not assigned

In November 1959 the USAF selected the Titan II/Centaur as the launch vehicle for orbital Dyna-Soar missions. The Air Force canceled this series of flights on 16 October 1961 in favor of missions to be launched by the more powerful Titan IIIC, during which the Transtage would remain attached to the spacecraft to provide orbital maneuverability. On the last schedule before the cancellation, the second Titan II/Centaur manned orbital flight was probably set for December 1967, interpolating from multiple documents. Although the Dyna-Soar Titan II/Centaur manned orbital program was terminated before the Air Force assigned astronauts to specific flights, it did select a group of test pilots for Dyna-Soar in April 1960: Neil A. Armstrong William H. Dana Henry C. Gordon William J. Knight Russell L. Rogers Milton O. Thompson James W. Wood The Air Force had previously selected Neil A. Armstrong in 1958 for its Man In Space Soonest program. NASA selected him in Group 2 on 17 September 1962. The Dyna-Soar program insignia shown above depicts the spacecraft on a Titan II.
