In the archives of aviation history, a remarkable incident unfolded over the night skies of Tehran, Iran, on September 18-19, 1976. This event is widely regarded as one of the most extensively documented UFO-aircraft encounters ever recorded. It began with the breach of restricted airspace over the Iranian capital, Tehran, by an unidentified flying object (UFO), sparking intrigue and fascination among those who would come to know of it.

Reports initially surfaced from local citizens who observed an unknown object hovering at an altitude of approximately 1,000 feet above the ground in the northern section of Tehran. At first, these calls to the Control Tower at Mehrabad Airport were met with skepticism, but as more reports flooded in, it became impossible to dismiss the phenomenon.

Hossain Perouzi, the night shift supervisor, decided to investigate further. Since the radar system was offline for maintenance, he relied on binoculars to scrutinize the object. What he witnessed defied explanation—a rectangular or possibly cylindrical object, measuring around seven to eight meters in length and approximately two meters in width. It exhibited pulsating whitish-blue lights at both ends and featured a small red light in the middle, which moved in a circular motion. Perouzi’s description left him astounded, unable to fathom the true nature of the object.

Around 12:30 a.m. on September 19, Perouzi made a crucial decision, contacting the Air Force Command post to report the UFO sighting. The Base Commander, in turn, authorized the scramble of an F-4 Phantom jet from Shahrokhi AFB to conduct a closer examination. This marked the beginning of a series of extraordinary events that would baffle both the Iranian Air Force and the U.S. military.

The first scramble, conducted at 01:30 a.m., involved an F-4 jet that approached the UFO within 25 nautical miles. However, as it drew closer to the object, the aircraft experienced a sudden loss of instrumentation and communications. It was as if the UFO possessed technology capable of jamming their systems. Wisely, the F-4 pilot decided to disengage and return to base. Curiously, as the F-4 distanced itself from the UFO, its systems miraculously returned to normal.

Undeterred by this unusual encounter, General Nader Yousefi, the Base Operations commander, authorized a second scramble at 01:40 a.m., this time piloted by Lt. Jafari. This F-4 managed to establish radar contact with the UFO, revealing a massive, intensely brilliant object with lights flashing in a rectangular pattern of alternating blue, green, red, and orange colors.

What followed was even more perplexing. A smaller object emerged from the primary UFO and rapidly approached the F-4. The pilot attempted to fire an AIM-9 missile at the approaching object, but at that critical moment, the weapons control panel malfunctioned, and all communications were lost. The F-4 executed evasive maneuvers to escape the situation, and once again, when it distanced itself from the UFO, its systems returned to normal.


The astonishing sequence of events didn’t end there. The smaller object that had separated from the primary UFO descended and landed on the ground, leading to further puzzling developments. General Yousefi observed this landing from his Tehran residence, where he witnessed a connection between the mothership and the smaller object, with lights communicating between the two.

As dawn broke, the F-4 crew ventured to the area where the smaller object had landed, guided by a noticeable beeper signal. Although they found no visible traces of the object, local witnesses reported hearing a loud noise and seeing a bright light akin to lightning on the night of the incident.

Despite investigations, including checks for possible radiation, many details remained undisclosed. A report published in a classified U.S. military journal, MIJI Quarterly, acknowledged the strangeness of the events and how they defied logical explanation.

This incident is a classic example of a UFO encounter that meets the criteria for a valid study of the phenomenon:

  1. Multiple witnesses from different locations and viewpoints.
  2. Credible witnesses, including an Air Force General and qualified aircrews.
  3. Visual sightings corroborated by radar.
  4. Similar electromagnetic effects reported by multiple aircraft.
  5. Physiological effects on some crew members.
  6. Extraordinary maneuverability displayed by the UFOs.

In wrapping up, the 1976 Tehran UFO incident maintains its position as a pivotal and unresolved chapter in the history of UFO encounters. Its enduring significance is rooted in the reliability of the witnesses, coupled with the thorough documentation that ensued. From the eyewitness accounts of experienced air force members to the radar validations and the unexplained electronic disruptions encountered by the jets, each aspect contributes to a complex and intriguing narrative. As time progresses and our technological capabilities evolve, this incident continues to captivate and intrigue, serving as a stark illustration of the mysterious occurrences in our skies that remain beyond our current comprehension.
