But it's extra staggering considering the consequences which I'm sure is what OP meant :)

  Up until the last 40 years of human history almost everything was calculated and drawn by hand. Every building, machine, road, bridge, airplane, ship, and everything else was designed by hand with pen and paper. Given the times doing what they did would not be unexpected, i.e. doing a good job by hand. This doesn't take away from the work and accomplishment. But I see it more as a job well done then something truly out of the ordinary for the times.

    Digital desktop calculators were a thing since late 1960s, and helped a lot with these hand-driven calculations. They were large boxes with nixie tubes, the size of a modern midi-tower PC, only horizontal. They were limited to relatively simple operations, like square root or ln. They were more precise than a slide rule, though.
