Here's how to activate Google Earth's hidden Flight Simulator feature.
Note: I have only done this on windows, so I'm not sure if it works on Macs. So this Instructable is for WINDOWS ONLY!
Step 1: Install Google Earth
go to earth.google.com and install the free version of Google Earth if you don't already have it.
Step 2: Open the Program
When the insallation finishes, launch Google Earth from it's shortcut.
Step 3: The Secret Feature of Google Earth
To activate the hidden flight simulator feature, hold down Ctrl+Alt+A on your keyboard. A Sub-window should come up. Choose one of the two planes, choose your airport, and fly away. Click on the help button for flight controls. And yes people, this feature is compatible with joysticks!
