I've bothered to read the ATSB report a few times.
It describes a situation in which the controller couldn't make himself understood to the Emirates jet. It describes him as being assessed as incompetent during training, yet allowed to work as a controller, where he screwed up early in the day and then screwed up again with the Qantas and Emirates jets.
I'm scratching my head as to why such a dangerous person was allowed to keep his job and then screw it up twice in one day. Is he a one off or is ATC full of fools like this.
