The following document was just one of thousands of pages on UFOs released by the Central Intelligence Agency (CIA). In July of 2018, I requested a Mandatory Declassification Review (MDR) request on the record, since it had been many years since its last review, and it remained heavily redacted.
For reference, the CIA claims the material that remains redacted (which is pretty much everything) is due to Section 3.3(b)(1). This is defined in the executive order as:
Sec. 3.3 Automatic Declassification.
(b) An agency head may exempt from automatic declassification under paragraph (a) of this section specific information, the release of which should clearly and demonstrably be expected to:
(1) reveal the identity of a confidential human source, a human intelligence source, a relationship with an intelligence or security service of a foreign government or international organization, or a nonhuman intelligence source; or impair the effectiveness of an intelligence method currently in use, available for use, or under development;
The following is a table/side-by-side comparison of the previous release vs. the newest release. Captions will outline which page comes from which release.
