It appears to me -- with zero experience of flying this type of aircraft -- that recovery would not have required a great deal of height, once the wing was unstalled by trimming the THS and getting the pitch angle into the vicinity of the flight path angle, ie 20 degrees or so below the horizon.
Well, yes you could resume flying and generating lift, but you would be diving at a pretty severe angle and you have to generate enough G to turn the aircraft from that nose down path to horizontal. You have over 100 mph of vertical velocity and it's going to take some positive G to get rid of that. You aren't going to level out right away.
