A couple of questions from a dumb F$%, and they are not to imply in anyway this is whats happening, just technicality and enlightenment.
Roll rate, yes we know it can't roll that quickly commanded. But what is the roll rate with one engine out near stall maybe with some rudder kicked in?
Glide distance, yes pilots know the drill, optimum glide distance, too fast or too slow you fall short. But does that not imply a speed that the aircraft is under some sort of reasonable control, even up to landing. Not maybe opps we have some power, now we don't. Or the thing is flying when it really shouldn't be at the moment speed.
Regardless of the theory, controlled flight into high rises or houses may make you try for the illogical.
