Etops,
Your two posts have a rather poor standard of English, not entirely unlike Chinese ATC. Your comments demonstrate a level of thickness and surface level understanding only which I again compare to ... Chinese ATC. They are mostly unable to grasp the three dimensional picture as gweillos controllers are.
Bring in Heathrow, Kennedy, or O'Hare controllers and HKG could double its efficiency and capacity in a week. Even with the crappy approach / departure corridors and high terrain all around, they would find a way to get it done. These two runways are nowhere near full utilization. Of course, they might need an ATC penalty box for all the similarly pathetic Asian pilots driving many of these aircraft.
It's not racism, it's reality. The mainland can kick out all the expats, but all that will be accomplished is the further marginalization of an already struggling air traffic system.
Just ask Kunta in South Africa... Can you say, "Failed State?" That's what happens when you kick out all the educated and productive members of society.
