X-Plane 10 Beechcraft King Air Glass Enhancement. Up until now, the cockpit and cabin windows seen from outside the Beech King Air have always have been invisible. They were just holes to look though, without any "glass" to be seen. In the latest version of X-Plane (time of writing) 10.20 adding some realness to the glass failed again. Wait no longer. Just place the contents of the objects folder from this download into the main objects folder of the King Air. A backup for the default files is included. By Leen "Flybike" de Jager.
