Martin - I was the screener who rejected your picture, and was made aware of this thread from a teammate.
There just isn't enough airport left to make it a worthwhile addition to our database. At some point Kai Tek stopped looking like an airport as it was built up, this photo confirms it. Your photo, in my opinion, shows a nice night shot of the
HK skyline, and is not aviation-related to be included here.
If you disagree with my assessment I encourage you to submit an appeal, so that the Head Screening team can make a final judgement.
