The Iranian F-4 UFO encounter of September 19, 1976, stands as one of the most thoroughly documented and technically compelling UFO cases in aviation history. When Iranian Imperial Air Force F-4 Phantom jets were scrambled to intercept an unidentified object over Tehran, they encountered phenomena that challenged conventional understanding of aerospace technology and electromagnetic physics.
This extraordinary incident involved multiple military aircraft, experienced combat pilots, radar confirmation from various sources, documented electromagnetic interference, and official documentation by both Iranian authorities and U.S. intelligence agencies. The case has become a cornerstone of serious UFO research due to its combination of credible witnesses, technical data, and official recognition.
The Iranian F-4 UFO encounter began in the early morning hours of September 19, 1976, when Mehrabad Airport control tower received multiple telephone calls from residents of Tehran reporting a large, bright object in the sky. The object was described as larger than a star and displaying multicolored flashing lights.
Initial Response: After visual confirmation by the control tower supervisor, Iranian Imperial Air Force Command was notified. The decision was made to scramble an F-4 Phantom II jet to investigate the unknown object.
First Intercept Attempt: Captain Mohammad Reza Azizkhani piloted the first F-4 that was launched at approximately 1:30 AM. As his aircraft approached within 25 nautical miles of the object:
Second Intercept Attempt: A second F-4, piloted by Major Parviz Jafari, was launched shortly after the first aircraft returned. Jafari's intercept proved even more eventful:
The encounter lasted approximately 1.5 hours total and was witnessed by multiple ground observers, tracked on radar, and documented in official military and intelligence reports.
The electromagnetic effects experienced during the Iranian F-4 UFO encounter were among the most dramatic and well-documented in UFO history, affecting sophisticated military aircraft systems in consistent and repeatable patterns.

Technical Significance:
The electromagnetic effects were particularly significant because they affected military-grade, hardened electronic systems designed to operate in hostile electromagnetic environments. The F-4 Phantom's systems were built to military specifications and included electromagnetic pulse protection, making the comprehensive system failures highly unusual.
The range-dependent nature of the effects, where systems failed within a specific distance of the object and recovered when withdrawing, suggested a localized electromagnetic field of considerable intensity emanating from the unknown craft.
The radar tracking of the Iranian UFO incident provided crucial corroborating evidence and technical data that distinguished this case from typical visual-only sightings. Multiple independent radar systems confirmed the presence and characteristics of the unknown object.

The radar data was particularly significant because it eliminated many conventional explanations such as optical illusions, astronomical objects, or weather phenomena. The multiple independent confirmations from different radar systems using various frequencies and technologies provided strong corroboration of the visual observations.
The CIA's involvement in documenting the Iranian F-4 UFO case represents one of the most significant official U.S. intelligence acknowledgments of a UFO incident. The agency's documentation provides crucial insight into how the U.S. government evaluated and analyzed credible UFO encounters during the Cold War era.

Impact on Careers:
The professional credentials and subsequent actions of both pilots, particularly Major Jafari's willingness to speak publicly about the encounter, have been crucial in maintaining the credibility and historical significance of this case in UFO research.
During Major Jafari's intercept attempt, one of the most dramatic and well-documented aspects of the Iranian F-4 UFO encounter involved the apparent launch or deployment of smaller objects from the main craft. These secondary objects displayed seemingly intelligent and purposeful behavior.

Witness Accounts:
The deployment of secondary objects added a new dimension to the encounter, suggesting sophisticated capabilities and potentially defensive or reconnaissance functions. The apparent intelligence displayed by these objects, particularly the first object's approach and withdrawal pattern, remains one of the most puzzling aspects of this case.
The Iranian authorities' response to the F-4 UFO encounter was swift, professional, and treated the incident as a serious national security matter. Their handling of the situation demonstrated the significance they placed on the encounter and their commitment to investigating the phenomena.
