Worked Approach Radar and Tower for a total of 12 years until Kai Tak closed. What a buzz. What I really enjoyed was combining the IGS and a Visual Step Down if the weather was suitable. Many airlines would not allow their pilots to do a VSD because of the local geographical knowledge requirements. No such restrictions for Cathay or Dragonair. If you had two aircraft coming in from the East with a Cathay aircraft about 12 nm behind another airline, I could clear that aircraft for an IGS and immediately clear the Cathay aircraft for the Visual Step Down. When judged correctly, Cathay now became No 1, no delay to anyone and enough room to get a departure in between both aircraft. Maximum use of airspace with both aircraft getting what they want. Talk about job satisfaction. Thanks for the memories to all who operated at Kai Tak.
