The fact of the matter is HK ATC have lost the plot in the last 12 months. Last Sunday was a prime example. Aircraft holding for 45 min and then having to divert due to HK ATC freaking out. Their excuse.... weather. What a crock of Sh!t. First of all.... the weather was not that bad and second, the unprofessional manner in which they refused to accept aircraft into HK airspace would NEVER have happened before all the good controllers left.
