The F117 required computers to fly as it would depart from normal flight if the computers went down. This is called negative stability.
I don’t think the F16 has that problem. It requires computers to fly but will stay in the attitude it was when the computers were lost (neutral stability). Its more complex than that but there are definately model F16s that fly.
Do a search on “airplane stability” and you will find some good sources.
Thanks driftdiver, I will do that.
