It started as simply adding aprons for the military stuff (most IRIAF aircraft seem to visit if they aren't actually based there), then I got annoyed with the civvie parking so fixed that, then I thought it was still missing something so I've started added the boneyard(s). Still a work in progress but starting to look more and more complete. I just wish I had the skills to create custom buildings.
Southwest fighter apron (for visiting military aircraft as well as a few trainers and tigers):

C-130s on the main IRIAF transport apron:

Transports:

Looking over the western civilian apron to the maintenance hangars (civil and military):

Stored C-130s

The main terminal:

Pair of 747SPs

Fokkers everywhere:

You wait, the one they need will be the one right in the middle of the herd:

Boneyard north of the airport, apparently theres some kind of open air museum up this end:

Southwest apron, at least partly a boneyard. I haven't added much to this one yet:

I hope to release this when its finished (FSX only), with instructions for the boneyards in case people want to add what makes this place much more interesting. Its not the only Mehrabad scenery for FSX, and I'm nowhere near good enough to make it the best, but the others don't really have the military parking, and miss out the aircraft shelters in the northeast of the airfield completely, so it must have something going for it...
I did have some more images of the aircraft shelters for the MIG-29s as well as the whole thing from above but they weren't that great so I'll take them again.
Still to do (no particular order):
1.Finish the boneyard aircraft.
2.Finish military parking (IL-76s are in the wrong place at the moment).
3.Taxiway names (assuming I can find a chart somewhere) and signs.
4.Add trees around the HAS sites.
5.Add a few military objects to break up the monotony of massivee empty aprons.
6.Fix those bloody cliffs.
7.And anything else I've forgotten.
