Kai Tak
I think some of the best approaches were made by the " Auxies " . We even were allowed to come from Sek Kong direct over Lion Rock and then sideslip down onto RW 13. Also, holding at North Point at 500ft and then given clearance to land in the last third of RW 23 and vacate the runway ASAP. Later,with the increase in traffic, things became more restricted but we still had a job to do.
I remember once in the 60's a flight from Singapore to HongKong. We refuelled at Saigon but after passing DaNang knew that if we carried on, we did not have fuel to divert to Manila. The weather was bad and I asked the captain what we would do if we could not get in to KaiTak. He looked at me and said that he did not want to be court-marshalled so he would fly into a mountain just above Lion Rock. As a fairly new co-pilot, I half believed him. Later ,in the bar ,the drinks were on me and the rest of the crew had a good laugh.
