KH-8 19 (GAMBIT 57) was launched on 1969 Jan 22 by Titan IIIB Agena D from Vandenberg. It entered an orbit with an unusually high apogee of 1090 km, suggesting the possibility that the Agena D failed to shut down on time; however, it is probable that the intended apogee was at least the 740 km of the previous flight, and that this mission should be grouped with the other high apogee flights. A debris object, 1969-07B, was tracked in a 130 x 694 km x 106.1 deg orbit on Jan 23; it may be a camera cover.
