NSA AFFIDAVIT ON UFO SECRECY (1980)

A classified affidavit originally filed by the National Security
Agency in a 1980 lawsuit to justify the withholding of records on
unidentified flying objects has now been largely declassified.

In response to the lawsuit filed by Citizens Against Unidentified
Flying Objects Secrecy for records pertaining to UFO phenomena,
the NSA sought to withhold numerous records.

The majority of these records, explained NSA official Eugene F.
Yeates in 1980 in his affidavit, were communications intelligence
reports that "are the product of intercept operations directed
against foreign government controlled communications systems
within their territorial boundaries."

"Revealing the contents of these reports would disclose the
capability of NSA to target these government controlled
communication systems."

The affidavit, originally classified Top Secret Umbra, was
released in redacted form on November 3 in response to a Freedom
of Information Act request from researcher Michael Ravnitzky.

UFO Secrecy v. National Security Agency, October 9, 1980
