I'll tell you the craziest airport I've flown into was on the island of Roatan, Honduras. The island is long and skinny, running east/west, with the airport runway running parrallel on the south side of the island. I did a google search and they said the runway is only 3400 feet
We flew in a TACA airlines 737 (we joked it stood for Take A Chance Airlines) which they probably bought after southwest or some other airline retired it. Anyways, the pilot enters on the base turn coming from the north over the island, turns relatively hard for a short final, and as we descend you see land appear underneath you out the window and just when you think you're about to touch down, you pass over water (there's a small lagoon right before the runway) and your like sh#t, sh#t, sh#t, then a sliver of land and *thud* you touch down and fly forward in your seat as the pilot applies reverse thrust/brakes to stop. Funny thing is I'm going back in December, should be fun...
