I’ve only flown into three of these, but as I was reading, I wondered if they would mention Saba. Sure enough, it’s number ten. I don’t recall either JFK or St. Maarten being that scary, from a passenger perspective, but we flew into there on our way to Saba, which is quite an experience. As noted, it is a very short runway, with a dropoff over a cliff into the ocean if you don’t stop on time. They fly very short takeoff/land planes in there. We flew in with a naval aviator and his wife who were stationed at Rosie Roads in Puerto Rico, and he said that it would be good training for a carrier landing, except that it was a lot more stable.
Anyway, it was worth it. A very quaint little Dutch tropical island, with a couple nice hiking trails around and up the mountain, with great views of Anguilla, St. Maarten/St. Martin, Nevis and other northern windward islands. And a marine preserve, for great diving.
