A very special day

Very interesting. One of my good friends used to work for NASA. He was one of the few (12 or so) guys that did the calculations for re-entry for late in the Mercury program and then he did Apollo. Some of his work (calculations) are on display in the Tulsa Aviation Museum representing the data used in a console in Houston during the missions.
He said that once you got the first one right, the rest were fairly straightforward (so says the guy with an aeronautical engineering degree AND astronautical engineering degree).
