The SR-71 was entirely calculated through slide rules. After the advent of computers, they asked a program to optimize the airplane's performance. It found it didn't need improving. Nobody misplaced decimals on that design. Crowning Moment Of Awesome to the Skunk Works engineers that ran the numbers by hand. Crowning Moment Of Math?
The same thing was common on NASA. The computers ran the numbers, but someone would double-check or at least Sanity Check the numbers with slide rules. A handful of examples on Apollo 13 movie.
