A new developer on the X-Plane.org forums has confirmed that they are making a brand new freeware Ibiza Airport and Island package for X-Plane 11. Developer Alliverti confirmed that the project is well underway and shared a range of new screenshots indicating current progress.
There is a lack of information at this time relating to features, release dates, etc. However, Alliverti did confirm that the freeware package will feature handplaced vegetation and objects throughout the island and airport. It will also require the OpenSceneryX and MisterX libaries.
In other freeware news, we shared that ESOE Örebro Airport is coming to X-Plane.
You can follow this Ibiza freeware project on the X-Plane.org forums.
Thanks to Mikkel B for the tip.
