My Cousin worked at Harris and created the computer that made the final decision for the landing on the Moon. His design told them which of the 3 computers to believe in the final minutes.
The night they landed, we were watching it in the Sheep Meadow in Central Park in NYC. I remember the look of pride on his face when Armstrong said "Tranquility Base here, the Eagle has landed...".
He later worked on Skylab and the Shuttle. His final project was for Locomotive Communications and Control systems for GM.

To look back, we had a generation of very well trained Engineers and Technicians but we also learned from the mistakes we made. Apollo 1 was an example of getting too complaicent in our success. So was the Columbia.
