The N2s wound down to 60% and the Nr decayed until it reached the N2 needles ... Guess what! .... The rotors re-engaged and we sat there realising
Of course the needles re-joined, but that's not the same as being governed. Without engines the Nr will tend to zero, over time, but with residual N2 from idling engines the Nr will stop decaying. I hope you know this and are just chucking grenades! (the alternative is dismaying...)
and the airframe embedded, either the blades will thrash themselves or the input shaft will break?
That's a separate discsussion! (whatever embedded means)
