Safety Concerns
Stick feedback, throttle feedback, AOA indicators, direct law, normal law have had no effect on accidents for forty years.
I doubt you can support that statement, given how contributory factors add up in aircraft mishaps of any brand, not to mention the variety of change, modification, and adjustment the industry has made in forty years.
But let's try another view on this: is half a truth a whole lie? If it is, then you could be accused of lying (or simply being wrong) even if there is something in your statement close to the truth.
You can make a case that any single one of the above were not the sole cause of a mishap over the past 40 years, and my guess is that you'd be able to support it.
Since we may never get good granularity on the recent crash (early morning) in Libya, thanks to that bit of Arab Spring, whatever factors contributed to that remain lost to the industry at large.
(Here's hoping I am wrong about that).
