With the success of Kosmos 146 and in spite of the failures of the first three 7K-Ok’s it was now time to plan for a Soyuz manned mission. The planned involved the launch and docking of two piloted Soyuzes. Soyuz 7K-OK production model number 4 was assigned the role of the active vehicle. The active vehicle was supposed to carry one cosmonaut into earth orbit. Twenty-four hours later, vehicle No. 5 (the passive vehicle) carrying three cosmonauts would be inserted in orbit. After rendezvouing, two cosmonauts from vehicle No. 5 would transfer through open space to vehicle No. 4.
Around noon on January 14th, Boris Chertok was alone in his office studying a folder of classified mail that had accumulated during the past few days. He had asked not to be disturbed. Suddenly his subordinate ran in and shouted, “Sergey Pavlovich died!”
Chertok responded “Are you out of your mind? Which Sergey Pavlovich?”
“Ours, our Sergey Pavlovich Korolev! His wife telephoned from the hospital!”
Chertok stood absolutely dumbfounded, having no idea what to do next. This can’t be! This really shouldn’t be happening! A few seconds later he called the Kremlin for verification.
