I been to Shemya as recently as 2003. There are a lot of old barracks, but the current staff is about 200, mostly contractors. You usually need a letter signed by a general to get on the base. The airport reception area is small. The winds can be very dangerous for pedestrians. It is one of the most boring places in the world to be stuck.
“There are a lot of old barracks....”
There are worse places for 200 people to get stuck I imagine. I was working out of a small native village in Alaska. A mat in the basement of a church. A guy came in with food for breakfast and dinner. Well - the breakfasts were few. I was warned ahead of time so brought my own oatmeal.
