bubbers,

I agree entirely about the crew having to fly the aircraft.

And I'm not even so certain about an A320 in this case. Alpha-Floor protection is inhibited below 100ft RA. Which radio altimeter feeds it? What does it do when it gets "eight feet under"?

If automatic TOGA thrust were inhibited, it would still develop a high sinkrate at very high angle of attack. It may have hit the ground, tail first, just as badly, even if not technically "stalled". As Feynman said, "You can't fool nature", and the low-energy state of the aircraft will remain thoroughly unimpressed by computers.

The only thing that will impress it is to convert some chemical energy (fuel) into kinetic energy (speed).

Here as at Habsheim, that happened too late and/or too little.


On the other hand, B737s also had runway overruns at Sao Paulo, just not as catastrophic.

It is dangerous and complacent to say "This accident couldn't have happened in Aircraft type X".
