What is the most popular plane in the sim?

I disagree. The Connies were some of the best propliners ever produced for FS9. There was also Samdim’s (Dimitri Samborski) TU-114 that had a gorgeous exterior and brilliant VC that you could move around in. There were many times I’d come in for a landing, then go into replay mode and slide my viewpoint down into the navigators seat to get the view from the clear nose (which was the bombardier’s position when the plane was a bomber). For Boeings, few external models could compete with Kazunori Ito’s models released through Project Open Sky. He always pushed the polygon count to within less than ½% of the limit!
