When I was doing an IT project in HKG in 1994/95, I was staying Kowloon side (working in the container port at Kwai Chung).
One Sunday I took a long but planned walk from Kowloon under the flight path and followed the line up to the Chequer Board and then walked on down the flight line to the perimeter fence. Rode back on the bus. It was a great day.
