Key Facts: Iranian F-4 UFO Encounter

Comprehensive Analysis: The Iranian F-4 UFO Encounter

What happened during the 1976 Iranian F-4 UFO encounter?

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:

  • All communication and instrumentation systems failed
  • The aircraft began experiencing complete electrical failure
  • Azizkhani was forced to break off the intercept and return to base
  • Upon moving away from the object, all systems returned to normal operation

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 object was acquired on the aircraft's radar at 27 nautical miles
  • The radar return indicated an object roughly the size of a Boeing 707
  • As Jafari approached, the object appeared to launch smaller objects
  • When attempting to fire an AIM-9 Sidewinder missile, weapons systems failed
  • One smaller object appeared to approach Jafari's aircraft in an aggressive manner
  • Another object detached and appeared to land in a desert area

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.
