Few days back, TS (Terraserver) has published new aerial imagery for Kshesh airbase which was overrun by opposition on 13th Feb. 2013 and then was controlled by Jaish Al Islam. The imagery here is dated 26th Jun. 2016 in which we can see the mass chaos occurred to facilities of the air field; thus, I provided an earlier view of the same location dated Sep. 2010 for better comparison.
The first thing can be observed from these views is how JAI worked to shovel the soil which covers the HASes (Hardened Aircraft Shelters) and left them exposed to the concrete structure. I won't be surprised if JAI filled the HAS with soil then after...
Around Fourteen MiG-15/17s were shifted from the boneyard.
In addition to form obstacles all along the runways, those MiG-15/17s are scattered here and there as well.
A phenomenon really surprised me and then I linked it to another view I observed in Abu DhHoor AB is what is valuable in the wings of decommissioned L-29s to make JAI strip them from the airframes as can be seen above!!
The same happened in Abu DhHoor AB, the MiG-23s can be clearly seen (below) stripped from their wings (those airframes in the eastern part of boneyard).
