Intentional dive or Runaway nose down stabilizer is what I can think off. The video seems too unrealistic.
What do you suppose the loss of a ton of weight (VS) from the extreme aft of the fuselage (long lever arm) would do to the CoG? I would expect a severe and probably uncontrollable nose-over.

What would it do to the integrity of the hydraulic lines running to the rudder? And thus the availability of hydraulic control pressure for elevator operation?
