FS2004 Scenery--Austin Mueller Municipal Airport Circa 1961. Robert Mueller Municipal Airport served the Austin, Texas (TX) area since the mid 1930's. In 1960 the airport opened its new "Jet Age" passenger terminal. The most notable feature of the building was the control tower, a graceful, curved structure, with the cab at the top. This scenery represents Austin Mueller Airport in its very early days. Calclassic scenery libraries are required to show most scenery objects. Special thanks to Tom Gibson and Jesse Cochran.
