you are right toilet but key west is flat. Dominica has a 6000 foot volcano 3 miles from the end of the runway making the one runway useless and also puts a consistent 10-15 knot tail wind on the 09 which points out to sea. Beef Island might be 4500 or so but there are also mountains surrounding it. You cant even line up on a straight in final till less than a mile out. Even STT has an intersting departure procedure due to terrain right on top of it (maintain 25 degree bank through the gap to a heading of 140 or something like that as i remember). Its not a good enviornment for the 145.
