IOTL, the USSR launched an unmanned flight around the moon in a Zond capsule (Soyuz, but stripped down). The capsule would have been also capable of launching 2 cosmonauts to the moon and back, but the September 1968 flight around the moon had a flaw: the reentry to the earth's atmosphere was so hard that it would have killed the cosmonaut, and thus the Soviets postponned a manned test until after Apollo 8 flew around the moon and it was too late anyway. So, let's say a POD during the Zond 5 circumlunar mission. The craft reenters much more easily, and the Soviets launch a manned circumlunar mission in November 1968. The Zond 6 manned flight, ITTL, flies around the Moon and returns, with the cosmonauts singing the praises of the Communist Party all the way. What happens next?
