What's the worst airport to fly into?

There's no really bad airport these days. The most interesting is probably Fueng Chow, years ago, doing charter operations and very simple operations. There was no landing aid because it was a very physically, strangely positioned airport. It was built on the edge of a mountain. It had a flat area where they had a runway, and it had another flat area where they had the terminal, and that was all it consisted of. There was no land before the runway or land after the runway. It was... interesting.
