First launch of second series - 10 preproduction and 11 prototype rockets available. A total of 20 were fired; six failures in 16 launches. References: 283 , 344 .

Launched at: 2141 hours EST from AMR. The flight was unsuccessful, The missile impacted 14 77 nm from the launch pad. Mechanical failure of the guidance tilt program caused the missile to assume a very steep trajectory which resulted La. a short range flight. Missed aimpoint by 111,000 m. References: 439 .

Cruise stage tanks 1 and 4 empty. The boosters operated normally and the cruise stage ignited at Mach 2.95-3.0. At T+95 seconds there were problems at separation of the boosters, leading to cruise stage instability and an asymmetric airflow through the ramjet diffuser leading. This caused significant variations in thrust. The pressure in tank 3 dropped at T+160s econds and the ramjet flamed out.

Fire broke out in a simulated space cabin at the Air Force School of Aerospace Medicine, Brooks Air Force Base, Tex., on the 13th day of a 14-day experiment to determine the effects of breathing pure oxygen in a long-duration space flight. One of the two Air Force officers was seriously injured. The cause of the fire was not immediately determined. The experiment was part of a NASA program to validate the use of a 5 psia pure oxygen atmosphere for the Gemini and Apollo spacecraft. References: 16 .

The escape stage entered parking orbit but the main engine cut off just 0.8 s after ignition due to cavitation in the oxidiser pump and pump failure. References: 1 , 2 , 5 , 6 , 64 , 65 .

Unmanned resupply vessel to Mir. During launch first test of Buran ejection seat was made during ascent to orbit. The K-36M.11F35 seat was installed in an 'experimental droppable compartment' installed in place of the Launch Escape Tower engine on top of the shroud.
