As Wikileaks Ufo has already been cesnored, I publish here at least what is already known on Wikipedia about the 1976 Tehran Ufo incident with official documents to prove it.
1976 Tehran UFO incident
The incident, extensively 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.
