Used to live in HK as a kid and only ever flew into Kai Tak, loved coming into it over the city but the water approach was just as interesting since you didn’t see the land until you were down. My brother used to fly light aircraft in and out of Kai Tak as a member of the HK flying club and also flew in some RAF choppers from Sek Kong and said it was bonkers with all the 747s about where you’re in a single engine cessna.
Out house used to overlook the runway from Hong Kong Island (Northpoint) and we could see the planes coming in over Kowloon – spent many hours watching them come in.
We even say a Lufthansa cargo plane go off the end of the run way and watch the army come in and dismantle it – first thing they did was cover up the tailplane to stop any bad press. :)
