I agree with all your points. My discussion points were about the original comment about the need to 'overhaul' the system. Right now I bet there is an investigation going on into this incident and it will likely lead to appropriate changes. I also suspect that many different entities have just upped their trackers of incidents to collect exactly the trend data that can prevent future issues, just like they should be doing. In other words the current system doesn't need a safety overhaul because it is doing everything reasonable and doing it well and has the stats to back up that it is doing reasonable things. Arguing that the system is safe and doesn't need an overhaul is not the same thing as arguing that the system should start ignoring things.
