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. Blogger Marco Gallotta explains how to take off:
You can get a quick start by holding Page Up for a few seconds to increase to maximum thrust (thrust meter is the left bar of the lower-left meters). Once you've accelerated to a sufficient velocity use the arrow keys to take-off. The keys are in reverse as one would expect with any flight simulator, so use the down arrow to take-off. When you've gained enough altitude then stabilize the aircraft to a straight flight path.
crash complete your first flight you can re-enter flight sim mode from the Tools menu. A gaggle of keyboard shortcuts is available to control the plane, as well as joystick support, though this thing does take some practice to get any good with. There goes Saturday.
