Aerodrome control post. When you land on Mocha Island, the first thing you will find is this curious checkpoint for the exit and arrival of the aircraft. Strangely there was no one and seemed abandoned. I was in several traffic control and border posts in Latin America and the majority is in the same way. In this case there was no way to announce my arrival and I went to the inn without any choice. When I left I found the checkpoint also empty. The authorities of Mocha Island never knew of my presence no matter how long I had been there for a week touring the island. Mocha island. Chilean Pacific Ocean.
