Background
The following case is thoroughly documented within the United States Government’s files. It was the first document I had ever received under the Freedom of Information Act (FOIA) and will always remain special to me in that regard. But despite my personal connection, this case remains one of the most interesting cases you can find in official documents.
Wikipedia documents the sighting as the following:
The 1976 Tehran UFO Incident was a radar and visual sighting of an unidentified flying object (UFO) over Tehran, the capital of Iran, during the early morning hours of 19 September 1976. During the incident, two F-4 Phantom II jet interceptors supposedly lost instrumentation and communications as they approached, only to have them restored upon withdrawal; one of the aircraft also supposedly suffered temporary weapons systems failure, while preparing to open fire.
The incident, recorded in a four-page U.S. Defense Intelligence Agency (DIA) report distributed to at least the White House, Secretary of State, Joint Chiefs of Staff, National Security Agency (NSA) and Central Intelligence Agency (CIA), remains one of the most well-documented military encounters with anomalous phenomena in history, and various senior Iranian military officers directly involved with the events have gone on public record stating their belief that the object was not of terrestrial origin.
The document, obtained under the FOIA from the Defense Intelligence Agency (DIA) reads as follows (.pdf version):
What was strange about this case, was the fact that the document was “UNCLASSIFIED.” However, that was not the case for a document that I obtained from the National Security Agency (NSA) which had one major difference: an opening paragraph from a United States Air Force Captain. This document was classified “CONFIDENTIAL.” The statement read as follows (full .pdf version):
