Montana Aviation Research Site, Montana

The Montana Aviation Research site is at the former Glasgow Air Force Base, which operated from 1957 to 1976, primarily as a B-52 bomber base. As part of a redevelopment effort, it became the Glasgow Industrial Airport. In 1992, Boeing bought the 10,000 foot long runway and hangars, and has operated it as a sometimes secretive flight test center for military and civilian aircraft, especially in the winter, for cold weather trials, operated by a subsidiary of Boeing, the Montana Aviation Research Company. The rest of the base, with 1,223 housing units, and other buildings including a school, bowling alley, and officers club, have been bought and sold, but is mostly abandoned. One project was an attempt to turn it into a Christian retirement community, and it was renamed St. Marie. After that, starting around 2012, much of it was bought (by paying the back-taxes to the county) by a group of sovereign constitutionalists, whose intentions were unclear.
