NSA UAP/UFO COMINT Records Released After Disclosure Foundation FOIA Appeal
NSA-origin UAP/UFO-related FOIA production released publicly by Disclosure Foundation after a FOIA appeal. OCR text derived from the public PDF is not an official NSA transcript. Many March-April 1979 radar entries are assessed in the records as probably balloons, while selected older visual reports and redaction patterns remain useful for archival review.
