Tommy,
Your shots of Kai Tak certainly bring back memories. I used to fly in there once a month, for a couple of years in a B747 for BA. I'm surprised they were able to fly model jets there after it closed.
Then I'd spend a couple of days eating and shopping. I bought a lot of model stuff from Kevin Lee's Tact Cheong shop in Canton Road. I wonder if he's still there.
It is hard to find a piece of good tarmac from which to fly jets in the UK. Most of the abandoned wartime strips are gone, built upon or torn up and back to farm land.
