Gweilo,
I look forward to reading the offical HKCAD report about 9-18,to see what happened and why the traffic was allowed to build up to dangerous levels.As I said many lessons to be learned.
You will probably find that it will be used in UK Truce training,as an example of how NOT to do ATC.
Apart from that you wanted the thread closed,and then start it up again all by yourself.
Bye bye bigger fish to fly.
