This official archival PDF assembles government material concerning unidentified low-level activity reported at U.S. strategic installations during October and November 1975, including Loring AFB.
It provides the institutional record needed to place Loring inside the wider 1975 security chronology rather than treating it as an isolated legend.
The records document alerts and identification problems. Their cautious terms such as aircraft or helicopter should not be rewritten as confirmation of an exotic vehicle. Original source: https://reaganlibrary.archives.gov/public/2021-06/40-654-209237725-001-009-2021.pdf
