the high quality runway it provides and there is a lot of it too
Have you actually been there this century? Okay, the main's a mile or so long and the N-S about half that, but it's a patchwork quilt of temporary botch-ups, waiting for the big development spend.
It has other problems with the surface breaking up, can quite easily get prop. damage if you're not careful, also has a pretty restrictive weight limit for transport flights.
