1993 Tehran mid-air collision
The 1993 Tehran mid-air collision occurred just outside the Iranian capital city of Tehran on Monday, February 8, 1993, killing all 133 people on board both aircraft involved—an Iran Air Tours Tupolev Tu-154M, registered EP-ITD, and an Iranian Air Force (IAF) Sukhoi Su-24 attack aircraft. At the time, the collision was the deadliest aircraft accident on Iranian soil, and is currently the third-deadliest behind Caspian Airlines Flight 7908 and the 2003 Iran Ilyushin Il-76 crash.
On that day, EP-ITD, loaded with 119 passengers and 12 crew, lifted off from runway 29R at Tehran's Mehrabad Airport on a non-scheduled domestic flight to Mashhad International Airport in Mashhad. Simultaneously, the IAF Su-24, piloted by a crew of two, was on approach to Mehrabad's runway 29L. At about 14:16 IRST, the two aircraft collided in mid-air and crashed in the town of Shahr-e Qods, about 9.4 miles from Mehrabad. All 131 people aboard the Iran Air Tours airliner and both military pilots died.
