FBI agents interrogate Tsien Hsue-shen on allegations that he is a Communist. The same day his security clearance is revoked, making it virtually impossible to continue meaningful work in rocketry. The allegations seem unlikely to his associates at CalTech (his wife was the daughter of one of Chiang Kai-shek's leading military strategists). Two weeks later, Tsien announces his intention to return to China. Tsien, denied the possibility to work, becomes enmeshed in a tug-of-war between differing viewpoints in the US government bureaucracy: those that want to deport him as an undesirable alien, and those that want to keep him in the country because of what he knows.

First space station flight, two years before the American Skylab. Soyuz 11 was guided automatically to 100 m, then hand-docked to the Salyut 1 scientific station. Equipment aboard Salyut 1 included a telescope, spectrometer, electrophotometer, and television. The crew checked improved on-board spacecraft systems in different conditions of flight and conducted medico-biological research. The main instrument, a large solar telescope, was inoperative because its cover failed to jettison. A small fire and difficult working conditions led to decision to return crew before planned full duration of 30 days. Capsule recovered June 29, 1971 23:17 GMT, but when the hatch was opened it was found that the crew had perished due to a loss of cabin atmosphere. A pressure equalization valve was jerked loose at the jettison of the Soyuz Orbital Module. The valve was not supposed to open until an altitude of 4 km was reached. The three-man crew did not have space suits. The Soyuz was thereafter redesigned to accomodate only two crew, but in spacesuits. The actual Soyuz 11 Prime Crew was Leonov, Kubasov, and Kolodin. Dobrovolskiy, Volkov, Patsayev were their backups (and support crew to Soyuz 10). Kubasov was grounded by physicians few days before launch, and the back-up crew ended up going instead.

Docked with Salyut 6. Launched unmanned to provide return vehicle for Soyuz 32 crew of Lyakhov/Ryumin after Soyuz 33 primary propulsion system failure. Checked the operation of the spacecraft propulsion unit; transportated the crew of the Salyut-6 station back to earth. Recovered August 19, 1979 12:30 GMT. References: 1 , 2 , 6 , 32 , 33 .

Suborbital test of 1/8 scale model of Buran. Typical trajectory: ascent to 120 km; pitch down to drive model in atmosphere at 45 degree at Mach 18.5. None were reflown but at least 4 were recovered. References: 81 .
Docked with Salyut 7. Delivered to the Salyut-7 orbital station a crew consisting of flight commander V A Dzhanibekov and flight engineer V P Savinykh to carry out emergency repairs to inert Salyut 7 station and to conduct scientific and technical research and experiments. Returned crew of Soyuz T-14 to Earth. Recovered September 26, 1985 9:52 GMT. References: 1 , 2 , 6 , 32 , 33 , 51 .
