A Pilot - or Engineering problem?
The pilot who started the thread has honestly stated that it happened to him, when fatigued. It could also have happened in turbulent conditions or wind shear. The only saviour here is the go around if the condition is recognised. As most of us haven't had a tail strike we aren't too cognisant of its likelihood.
Engineering tricks which reduce elevator effectiveness at high AOA may well cause embarrasment in other critical flight regimes - terrain avoidance in extremis - stall recovery etc. Flap movement during landing moves the whole ballpark as the pilot is in a deeply eyeball and hand environment - an anologue human mode, based upon short term learned tactile values. And by the way Unctious - if you had a connection with the DC-10 I don't know - the DC-10 CWS on landing would continue to trim if the pilot held off too long - and that was just as bad - causing a very long landing.
There are two areas where improvement can be made:
One is in the initial design - especially on stretched models.
The other is in training of recognition of impending critical angles - best done in a sim. and with the Go Around as correct handling.
