A telecommunications engineer wrote about our first satellites that were placed into space. He went on to report that one of these satellites went into a peculiar type of shut down.
It was as if someone were taking it down module by module.
After the satellite was shut down it remained so for about several weeks.
The satellite then began to come alive in an orderly fashion.
He described how it was as if someone was restarting it in an orderly fashion.
Reinstalling the boards one at a time, someone with the knowledge of how to do such a technical job.
