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.

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.

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.

This document was classified “CONFIDENTIAL.” The statement read as follows (full .pdf version):
The following was created by The History Channel, on the hit series UFO Hunters. It is archived here for reference and further clarification of General Parviz Jafari:
