I think a lot of people now have calculated that it wasn't possible, but I wonder; 1) how much modern information, or information only openly available now, was used to determine that. 2) How long it took them to figure that out and what stress they were under trying the calculations. Taking a youtuber a few days to figure it out is already too long. 3) How much CPU processing it took to make the calculation? Just putting it into an Excel doc on a modern computer seems trivial now, but Cray-1's weren't available in the USSR and a modern computer is easily 1000x more powerful than one). Constructing the Fortran simulation would take time to write and debug, then running it on a soviet PDP-11 clone would take a lot of time too. A Cray-1 is 1000x faster, and a modern computer is 1,000,000X faster). Doing the creating and editing of a youtube video, compressing it with the codec and uploading it, would take a significant percentage of 1986's world wide combined computing power.
