Sorry but even as a non pilot, all this talk about 'push the stick forward and you're saved' is bit insensitive on this thread without knowing what happened.

It certainly didn't help 2 very respectable pilots on D-AXLA A320-232 over Perpignan when THS stayed nose up, with the combination of the AOA sensors freezing and normal law dropping out they were unable to save it with the above aforementioned method. After reading the report, i was worried by the lack of notification to the pilots, in that moment id expect 'USE MAN PITCH TRIM' to be slapping me round the face.
Or a clear indication:

Warning - Normal law FAIL
STATUS NOW MANUAL
Cause - AOA/ADIR mismatch(or the like)

Result - USE MAN PITCH TRIM
(?(perhaps added flashing if stick forward/backward exceeds Xseconds)) or AUTO PITCH TRIM DISABLED!

Would of been even nicer. (In this instance above i believe the PITCH TRIM warning dropped off the display shortly after ie changing flight law.) i stand to be corrected.

Then again what if the warning is wrong and all of it is sending you up the garden path?

If something similar had happened here im not sure id want to be on-board with ANY pilot at FL25(risky i know) or FL370, in that moment attempting to recover a stall. IMHO the transition from 'automated' to 'manual' and not in 'neutral trim' in the wrong moment without any clear reason is a worry, using any automated transportation.
As we have learnt even the most simple things in that moment to react can go undetected (flaps not extended on takeoff due to FB pulled on warning circuit muting the reminder to pilots they're not extended). Whilst not automated, had there been a clear warning, reaction should/could of saved the day.

I'm also shocked to read about lack of stall training due to lack of capability to do so for some aircraft. And still we have not put more pressure on all airlines to enforce real time streaming on capable aircraft with the rest to follow. MH370 whilst is rare, it needs to be answered it cannot be swiped aside as a statistic as some have mentioned here.

On the plus, I salute the many informative posters on here who clearly are outstanding professionals in their field and appreciate their fascinating analysis and input. I hope all of this debate can be focused on making our airways safer, negating the swiss cheese effect ever happening. Hoping no more families suffer this loss of professionals doing their job and PAX in this way, once we have the ACTUAL cause from the experts.

Anyway what do i know, i can barely fly a quadcopter!
