The 1976 Tehran UFO Incident: Declassified DIA Intelligence and Flight Interception Records

The Initial Sighting\nIn the early hours of September 19, 1976, the Iranian Imperial Air Force (IIAF) received multiple reports from civilians and air traffic controllers at Mehrabad Airport regarding a large, brilliant light in the sky. The object was described as alternating between blue, green, red, and orange, and possessing a luminosity far exceeding that of stars or known aircraft. At 1:30 AM, General Yousefi, the assistant deputy Commander of Operations, authorized the scramble of an F-4 Phantom II jet from Shahrokhi Air Base to investigate the intrusion.\n\n## First Interception Attempt\nThe first pilot, Lieutenant Yaddi Rezande, approached the object but reported that as he closed to within 25 nautical miles, his aircraft suffered a total loss of instrumentation and communications. Fearing for his safety, Rezande turned away from the object; remarkably, as soon as he increased his distance, all electronic systems returned to normal functionality. A second F-4, piloted by Lieutenant Parviz Jafari, was then launched to continue the pursuit. Jafari was able to gain a radar lock on the object, which he described as having a radar cross-section similar to a Boeing 707 tanker.\n\n## Dynamic Engagement and Secondary Objects\nAs Jafari attempted to close the distance, the primary object suddenly released a smaller, brilliantly lit object that accelerated toward the F-4 at high speed. Jafari attempted to fire an AIM-9 Sidewinder missile, but his weapons control panel and radio failed the moment he engaged. He performed a sharp evasive maneuver, and the smaller object circled back to rejoin the primary craft. A third object was then observed descending from the primary craft and landing gently on the ground in the Rey reservoir area, illuminating the desert for miles. The primary craft then accelerated away at a speed estimated by ground radar to be well in excess of Mach 10.\n\n## Intelligence Analysis\nA four-page Defense Intelligence Agency (DIA) report, later declassified and archived by The Black Vault, stated that this case is a classic that meets all the necessary conditions for a legitimate UFO sighting. The report highlighted the high credibility of the witnesses, the electronic counter-measures (ECM) utilized by the object, and the physical radar confirmation. The event remains one of the most significant military encounters with UAP in history, documented by both Iranian and US intelligence agencies.
