Incidentally, the Mataveri International Airport (IPC) was once designated as an abort landing site for NASA's Space Shuttles when they were planned to be launched into polar orbit from Vandenberg AFB on the West Coast. Unfortunately, with the Challenger disaster, that never happened, and plans to use IPC were scrapped as well. I doubt that has anything to do with the facility you visited, but interesting none the less.

I'm actually writing up an Easter Island trip report now. Just went in early November!
