Flight Simulator in Google Earth 4.2

"Not only did the latest version of Google Earth add Sky—it also quietly got a fabulous new flight simulator which flies a virtual airplane (either an F16 'Viper' or SR22 prop plane) from an airport and runway of your choice. To switch into flight simulator mode the first time, launch the latest version 4.2 of Google Earth (free download) and hit Ctrl+Alt+A (Mac users: Cmd+Opt+A.) Choose your plane, airport and runway and go! Well, ok, it's not quite that easy."
