Verticalsim has released First Flight Airport (KFFA) as freeware for Microsoft Flight Simulator. The first freeware airport from the scenery team is located atop Kill Devil Hill and is most famously known for where the Wright brothers carried out pre-flight gliding experiments.
There is little information from Veritcalsim on the freeware airport, but from the screenshots, there appears to be custom ground textures and the inclusion of the Wright Brothers Memorial statue.
First Flight Airport from Verticalsim can be downloaded for free from their website. Installation instructions can be found also on their website.
