📍 Tehran, Iran 📅 September 19, 1976 🔍 Military engagement, system failure, U.S. Department of Defense records

In the early hours of September 19, 1976, an extremely bright unidentified object appeared over Tehran, Iran. The Iranian Air Force ordered two F-4 Phantom II fighter jets to intercept.

First F-4:

• Upon approaching to within 30 nautical miles, all communication and navigation systems failed
• The pilot turned back, and the systems immediately returned to normal

Second F-4:

• Approached again, and the missile system locked onto the UFO
• Just as it was about to fire an AIM-9 Sidewinder missile, all weapon systems suddenly lost power
• At the same time, the UFO released a smaller luminous object that flew at high speed directly toward the fighter jet
• The pilot took evasive action, and the small object circled back to the main UFO
• The main UFO instantly departed at an untrackable speed

The U.S. Defense Intelligence Agency (DIA) later declassified this report, describing it as “unexplainable,” concluding that “the object demonstrated capabilities beyond known technology.”
