We made four trips to the Sand Point airport, four days in a row, before a plane could finally land to take us to Anchorage. This is Unga, the next island over, behind the fog. The way they determine whether or not a plane will be able to land is by visibility of Unga. These planes fly by sight, so if it's too foggy to see over this part of the island, they won't land (in the first three attempts, we could hear them flying over and turning back each time, as we jumped up and down flailing our arms and yelling). In King Cove, they have a similar setup. One time, they had missed so many planes, they were instructed to all park their cars near the end of the runway and turn on their headlights. Reportedly, the plane was able to land. We already had everything packed for our next two month travel, so we left it at the airport each time (no sense in lugging 1100 pounds of equipment back and forth).
