2021-03-02 Space Shuttle Was Not Analog

From comment

Others are saying that this is analog. But even before the Shuttles the Apollo used a digital computer for guidance. I’m sure that in the years after the Apollos, they had even more digital equipment. And the analog days of the early 60s and before were mostly gone by this time. The major advancements in digital technologies were made by the NASA space programs.

All the switches, indicators and meters were for the highly trained astronauts to diagnose problems and override the digital systems. It was later that the switches and indicators were moved to buttons and annunciators on a touch screen. That’s when the software glitches like the 737 Max crept in.
