If we step away from the traffic controllers nonsense for a moment, the actual problem sounded like a military pilot to me. It's my understanding that people who have a family line of pilots go into that funnel knowing a specific nepotism related result occurs such that when it comes time to become a commercial pilot you are probably from such a family.

I have no idea if helicopter pilots work the same way or are starting to work the same way, but whenever I see a BS move like this I think that there's probably an opposite interpretation that doesn't fit what their demographic wants to hear.

Robust systems are designed to avoid single points of failure. Humans are fallible. So, for example, both the pilot and the air traffic controller are intended to be paying attention so that if one of them makes a mistake the other can pick it up. If the pilot is making an error, the air traffic controller gets on the radio to tell them they're getting too close to another aircraft, in time for them to course correct.

If air traffic control is under-staffed, now the warning the pilot gets might come a minute later than it would have otherwise, and already be too late. Then you no longer have a robust system and it's only a matter of time before one of the pilot errors the system was designed to be able to catch in time instead results in a collision.

  • There's obviously some number of mistakes one party can make in a single incident such that the other has a limited probability of preventing an accident. If flight control is the robustness, it would take flight control with a lot of free time to be reducing those mistakes in pilots by following up on all sorts of errors unrelated to an incident until a pilot rarely makes multiple overlapping mistakes.

    • You're still going to try to reduce the errors by each party as much as you can. The point is that if they each do the right thing 99.9% of the time, the overlap allows you to prevent a problem 99.9999% of the time. Whereas if you compromise one of them so that it's 80% instead of 99.9%, the chance that something makes it through the net increases by a factor of 200.

    They did.

    Pretty sure military aircraft just don’t have to listen to them.

    • They did after it was too late, because the crash happened. Unless the crash was intentional (and I'm not aware of any evidence of that), getting the warning sooner could have given the pilot more time to correct.
