Process is important. Process delivers outcomes. But the outcome stands by itself. No form of transportation is safer than US 121.
That's a good trend, but not a guarantee of safety.
The Concorde was the safest airline type then world had ever seen. In a few seconds it went from the safest type in history to the most dangerous. Turns out it had systemic problems all along, just took time for odds to catch up to them.
Processes and systems are what guarantee safety over the long term, not yesterday's performance. I've lived through a few regional cycles, and we entering another cycle of rapid attrition, hiring, and upgrade at the regionals... there is no way that will not be a factor. The only mitigation is that there's probably not going to be a lot of regional growth (mature scope).
