I spent two weeks on Shemya, it is closer to Japan than Anchorage.
At the time (late 80s) they claimed to have the world’s largest collection of video tapes.
Constant wind every day all day. The quonsets and hangars howled all the time.
I know a guy who spent some time on Shemya (electrical engineer/contactor).
Said when he got there, they had to get down on their hands and knees to crawl from the airplane to the base ops building because the wind was too bad to walk.
