this aircraft would have been showing serious control problems from vibration during flight, and most likely vibrate to a point that scared the life out of the passengers and crew or create a noise that would be clearly noticeable in flight.

You mean, control problems such as several sharp, hard-over rudder movements?

See my post just above yours.

It would be in both directions, not just one, and once in the diretion of the crack-to-open, THAT would be a certain hard over rudder!

One to GROUND the airplane by any smart pilot!

That is one reason I dont believe it is fatigue, it would be too obvious, the tail FAILING to cause a hard rudder movement, and to SEE the damage there, that would be obvious to Ray Charles as an inspector!
