I simply have to say it again:

It is a puerile reflex to defend any design shortcoming by stating that the "other" design had accidents too!

Grow up, please!

Sure enough you can stall a yoke as much as a stick. Once more: It is not about stick or yoke, not about conventional or fbw.

It is about enabling the pilot at commands still be the commander.

If you deprive him of primary sensory systems, then the design is worse than the one that still has those.
If you deprive the last resort (pilot) of FULL control by sometimes not processing his commands, then the design is worse than the one that still allows this.

Both designs may be fbw and stick-driven, that is NOT the issue. Both may work almost the same way, have the same protections, even programming commonalities.

But the difference I pointed out, sensory feedback and ultimate control, is the flaw in the Airbus design.

It would take very little to implement this:

1. A simple rumble-stick from the gameshop around the corner has primitive feedback, weighs almost nothing more, and is simple to install.

2. A simple escape-button, that functions analogue to the complicated procedure of switching off 2 prime and one sec, thus giving instant direct law, would be just as simple and cheap enough to install.

With these both features, the Airbus would be a very nice plane to operate.
