Previously-unseen video footage has surfaced online, allegedly showing the crash of an Iranian military jet at an air show two years ago. It captures the moment the Ilyushin IL-76MD military plane falls to earth and explodes, after a mid-air collision with F-5E Tiger II. The haunting video was filmed by the crew of a C-130 that was filming the refuelling of an F-4 Phantom II. The planes were taking part in the September 22, 2009 air show and parade just outside Tehran. All seven crewmembers on board the IL-76MD were killed in the crash.
