The story goes that sometime before midnight on September 19, four Tehran residents began telephoning the local Mehrabad airport stating that they saw a bright light in the sky. Mehrabad’s radar was under repair and was not operational, so General Yousefi phoned Shahrokhi Air Force Base at Hamadan, 275 kilometres west-southwest of Tehran.
They showed nothing on radar. Yousefi went outside and saw the bright light for himself. He then ordered a McDonnell Douglas F-4 Phantom fighter plane, piloted by Lt. Yaddi Nazeri plus a back-seat weapons officer, to have a look. It took off from Shahrokhi an hour later at 1:30am. Once Nazeri reached Tehran, he reported losing all instruments and communications, so turned around and returned to base, and reported that his instruments came back once he did so.
A second F-4 was launched at 1:40am, piloted by Lt. Parviz Jafari. Jafari acquired radar lock on the bright object at a range of 27NM. According to the F-4’s radar, the object had a signature similar to that of a KC-135 Stratotanker. Jafari reported that its lights consisted of alternating strobes of blue, green, red, and orange, so fast that all four were visible at once.
The F-4 pursued the object to the south of Tehran. It dropped another bright object out, which Jafari believed to be heading straight for him, and he attempted to engage it with an AIM-9 Sidewinder infrared guided missile. But upon doing so, he lost all communications and his weapons console. He turned away, and saw the second object apparently rejoin and merge with the first object. Moments later another bright object came out and went straight down into the ground, leaving a bright trail, and lighting up a large 2-3 kilometre wide area.
Jafari prepared to land at Mehrabad rather than return to Shahrokhi, and during approach experienced further intermittent communications and navigation failures. A commercial airliner in the vicinity also reported communication failures, but did not see anything.
The next day, Jafari and his back-seat officer were taken out in a helicopter to have a look at where they thought the light hit the ground. Nothing was found, except they did pick up the beeping from a radio transponder. They homed in on the signal to the vicinity of a house, where the occupants knew nothing except they’d heard a loud noise and a bright flash of light during the night. And that’s where the story ended — lots of strange events, and no explanations. Still very interesting.
