I remember flying into Kai Tak vividly from the old days.
However, I've only experienced the landing at Kai Tak coming in from land TWICE.
Every time I landed at Kai Tak in a 747 it was always landing from the sea.
However, I have experienced a take off in the landward direction in a 747 though. I remember flying JL 747-200 that way in 1979--you could feel the rapid climb and the hard bank to the left after leaving the runway.
