Clicking on any site on the interactive map returns in-depth information on that site, including related photo galleries (if available), current activity, and in some cases, such as Site #14, re-purposing notes. Site #42 on the map is the installation at Stephenville, Newfoundland near to Harmon AFB which in 1950 was home to me.
