Further to Meikleour's post #110, to be more precise the GS antenna sat on top of the west facing chequerboard but the LOC antenna was down in the sports ground to the right of the soccer field in the photo showing the newly painted chequerboard.
Re Preon's post #108, RAF Vulcans were rare visitors to Kai Tak in the years I was there (1969 & on). There was one that had an engine issue circa 1969 and was towed over to the Haeco maintenance area for a high power engine run. The noise was deafening but several of us got to have a look inside afterwards before it was towed back to the RAF area.
