Ilyushin 76MD jet crashes after engine fire or collision (depends on which source is correct)

The IRIAF Il-76MD "Simorgh" jet was destroyed in an accident near Tehran, killing all seven crew members. The "Simogorh" is an Il-76 jet modified with a radar dome on top of the fuselage for airborne early warning and control (AEW&C). It has been reported that the crew reported an engine fire. While maneuvering for an emergency landing at Tehran-Mehrabad Airport (THR) runway 29L the radar dome detached, striking the tail fin. Control was lost and the airplane crashed. http://aviation-safety.net/database/record.php?id=20090922-0 Or it could be this accident http://en.wikipedia.org/wiki/2009_Iranian_Air_Force_mid-air_collision A fly-past by the Iranian Air Force was part of the parade. An AWACS-equipped Ilyushin-76MD was to be escorted by several Northrop F-5E Tiger II aircraft. The Il-76MD and one of the escorts collided in mid-air, with the Ilyushin subsequently crashing in flames at Varamin
