How do you recover without unloading (diving) the aircraft?
This situation has been discussed elsewhere (|including by myself), and the conclusion seems to be that there are very few options left. A gradual reduction in engine thrust, to slowly reduce airspeed below 250kts is a theoretical possibility. However we do not know what effect the reduction in thrust would have on nose down pitch, due to the underslung engines. In any case, this is morbid curiousity, and should hopefully never again be encountered, particularly under these exact circumstances.
Edit:
DaveReidUK There seems to be little clear data on the trim forces of a loaded horizontal stabiliser in that flight regime. More research may be needed, if the accident investigation justifies it.
