Here, via an aviation website, is a rather startling Syrian rebel video of a Syrian Air Force MiG-29; as the rebels are filming the aircraft, it maneuvers directly towards the camera, opens fire with its gun, and the video abruptly ends with confusion and an "Allahu Akbar." Not a comfortable place to find yourself. Though designed as an air superiority fighter, Syria has been using the Mig-29 in a ground attack role; the 30mm cannon on its left wing has a 100-round magazine; that's what's being fired at the camera here. A 30mm round is serious business.
The Arabic in the upper left reads "Islamic Front: Army of Islam."
