The flight was climbing when the altitude record abruptly ended.[8][10] A video, circulated on social media, purportedly shows the moment of the crash. The video suggested that the plane was on fire when it began to dive, with some of its parts breaking up in mid-air.[11] It then crashed between Parand and Shahriar and exploded.[7] ISNA did not confirm the authenticity of the video, but it did state that the plane was burning prior to the crash, leading to speculation of a possible shoot down.[12][9]
