You would expect to enter a spin as a result and once in that regime, you MIGHT be able to stop the spin and recover in something over 12,000 feet of lost altitude. Not a pretty picture. One characteristic of the bird is that in high G maneuvers it would "depart" before it would stall/spin. That feature would give the pilot a fraction of a second to release the control input and maybe avoid the impending nightmare scenario. A departure feels very similar to the end of the acceleration during a catapult shot off the carrier. One microsecond you feel tremendous G forces and suddenly you feel as if you go to zero G. I think that is probably very close to what is happening. A departure is really likely nothing more than a high G stall. Don't ask me how I know what those sensations are like.
