Originally produced by John Stinstrom for FS9 and now recompiled to work in both FSX and P3D_V4.5 (not V5 compatible). All objects were compiled using the FSX SDK and look perfect in both Sims. There are several caveats to Johns original, one being that the additional objects from MAIW that were used in the FS9 version are not part of this scenery. The other caveat is that while John added landclass and various other vector polys those are also not part of this. The scenery update was built on Orbx Basic and Vector Landclass and is at it's best when used with those addons.
If you wish to add various AI packages from MAIW, feel free to download and install those as necessary. Enjoy!
