While you may still be playing around with the latest feature on GE 4.2, there’s a hidden feature that you may not yet know about. It hasn’t been publicized by Google yet, but it’s way cool.
By pressing CTRL+Alt+A in GE 4.2 you’ll be able to load and run a flight simulator around the world.
It takes some getting used to – seriously. I found the easiest way for me was to use my mouse, but they also offer keyboard shortcuts for all your typical commands.
It’s a very cool new way to see the world.
