Investigation Number:AO-2008-059 from the ATSB -
Investigation: AO-2008-059 - Midair collision
I may be missing something, but the 'Final Report' states that:
In the time leading up to the collision, the air traffic controller workload had been high and relevant traffic information was not issued to the pilots in sufficient time to assist self‑separation.
I hesitate to question, but this seems to be a blanket condemnation of the controller, albeit with a couple of caveats. Admittedly, I'm not good at navigating around, but can't find the basis for what appears to be a harsh conclusion with no supporting evidence.
My concern is for the poor bloke who's probably been sweating this for close to three years - now we have this.
Does anyone have some reference (ATSB?) that supports this particular conclusion.
