Absolutely fascinating to hear what goes on that isn't heard by the us on the frequency (the coordination with "centre")... certainly reinforces the need for good ATC.
But sadly how they are funded / who they are employed by (whether govt or private) may not necessarily impact on how good the service is that is provided, and thus I imaigine that the funding argument may not be impacted by this illustration of the importance of the service (unless the argument is to have no service?)
