FSX/P3D. Among his scenery projects, MSK has been taking a stab at aircraft among which the Pakistani Saab Mushshak which was very good. I wrote a review on that one. He has been developing the French Aérospatiale Alouette III that I believe is currently in the coding process but we are all waiting on an update on that. In the mean time, MSK has moved up to something much larger and thus far is looking extremely promising. We'll be watching this project very eagerly. More information via the source link.
