Hi kens,

Thanks so much for the information. I am familair with the voting logic (I've worked on systems that implemented the same thing, odd-number of processor cores and the majority wins).

One question, were any "misbehaving" processor or actuation requests ever logged? As in, were there examples where one actuator or CPU didn't agree in the Shuttle flights?

what a treasure-trove of historical technical info you have

do you know anything about the military's secret space-shuttle still in operation?

I'm sure it's either been very modernized or runs on completely different design since it's supposedly remote-control
