As an aside, I always thought IPC was the most remote IATA airport on earth (as in no other nearby airports to divert to). For flights between SCL and IPC, origin and destination are the closest diversion points. According to Wikipedia, Chilean authorities have even put a restriction on air ops; only one a/c in flight at a time can be closer to IPC than the alternates of SCL and PPT so if the plane is somehow disabled on the runway at IPC, another a/c headed there won't find itself unable to land. Certainly no wing tip pairs to/from this airport!
