The facts speak clear and loud and are beyond the realm of speculation: The cockpit shows traces of shelling! You can see the entry and exit holes. The edge of a portion of the holes is bent inwards. These are the smaller holes, round and clean, showing the entry points most likely that of a 30 millimeter caliber projectile.
This plane was shot down. NOT form ground Anti-Aircraft fire. But by another fighter jet from in front of the Plane.
The edge of the other, the larger and slightly frayed exit holes showing shreds of metal pointing produced by the same caliber projectiles. Moreover, it is evident that at these exit holes of the outer layer of the double aluminum reinforced structure are shredded or bent – outwardly! Furthermore, minor cuts can be seen, all bent outward, which indicate that shrapnel had forcefully exited through the outer skin from the inside of the cockpit. The open rivets are are also bent outward.
