It's not entirely fair to choose this flight as a random sample, but assuming for a moment that it is.. The pilot has a 85% or lower, how many 9s on the controller fix that?

If controllers were like traffic cops they would take time to raise or remove that 85% when they caught it and pay limited attention to current traffic to take actions to reduce future traffic risk. But they are not that as you just explained again.

It's not about a particular pilot, it's about the system as a whole. As long as 99.9% of aircraft don't require any remediation, the air traffic controllers have the bandwidth to catch the few that do. Until you don't have enough air traffic controllers.

The pilot is an example consistent with no actions to correct pilots. Double controllers and these pilots can now fly twice as many missions before they kill someone.

Controllers talk like an extra 9 for them is the focus and it is for them, the public acting like their ceremonies are about fixing the majority of the problem is a bold faced lie.

[AnthonyMouse]

There are already many actions to correct pilots. But human efforts are never perfect and we don't expect them to be, for both the pilots and the air traffic controllers. Which is why they're designed to backstop one another, and why compromising either one of them increases the probability of a collision.
