UFO mythos...S4 has been cited by many different "informants" over the years, and Wright Patterson (Wright Field at the time of Roswell) is named in
numerous UFO related documents. If you've ever seen the old "recovery guide" documents, you'd even see the various locations that different kinds
of alien-related materials were sent to. Technology went to S4, biologics went to WP...(guide was from the 60's). Seeing as how S4 is still
extremely isolated, despite the exposure of Area 51, there seems to be no reason to move a facility that's been in operation for around 40
years...when it can still serve it's function fine...
Janet flights to the base still continue last I checked....
