On the X-Plane.org forums, an individual named Daniel af Cee has announced his intentions on developing ESOE Örebro Airport for X-Plane 11 as freeware. The airport is around 90nm from Stockholm in Sweden and serves primarily as a cargo hub with some passenger traffic. Alongside civil traffic, the occasional military aircraft uses Örebro Airport.
Details on features are scarce right now, but Daniel did state that he will be using Sketchup for the buildings, along with use of the MisterX and OpenSceneryX libraries for ground and clutter.
We will keep our eyes peeled for future information. You can watch the project develop on the X-Plane.org forums.
