What if Sergei Korolev died in Siberia and the Von Braun was killed by Allied bombing during World War II? Would the space race still happen? If the space race still happened, who would lead space program development for both sides? (Maybe US Airforce and Chelomi) And how would the rockets and spacecraft look if the space race happened? (I honestly don't know, but I think the X-20 DynaSoar would have been finished and some sort of Titan II derived LV would be the Saturn V analog. No idea for the USSR)
