up and running with Google Earth Flight Simulator Online

I’m excited about Google Earth Flight Simulator Online (GEFS). It’s an online flight simulator based on Google Earth that runs in a web browser.


  • Built on Google Earth: worldwide photo-realistic sceneries
  • Simulate fixed wing aircraft, helicopter, paraglider and hot air balloon
  • Supports joystick control
  • Realistic flight model (lifting-line theory)
  • Real-time weather, dynamic wind lift
  • Multiplayer! fly and chat with other pilots across the globe
  • Over 30,000 runways and global airspace map

Unfortunately, it was a bit hard to get running smoothly on my Mac. Frown
This video is the game malfunctioning with the current version of Google Earth Plugin on Mac OS X 10.8.5:

Not that awesome. If you are experiencing problems as demonstrated in the video, here’s how to get it to work (as of September 2013):

  1. If you have Google Earth installed on your Mac, including the Google Earth Plug-in, check its version here. If you have a version newer than, you will need to downgrade from the link in the next step.
  2. If you don’t have the plugin installed, don’t install the newest one. You’ll need to use Google Earth Plugin for Mac [download] – a few releases older than the current Google Earth package. The current one doesn’t play nice with GEFS-Online.
  3. Use the Safari web browser. Google Chrome and Firefox didn’t work well for me.

Once you’re up and going, it’s a wonderfully detailed and reasonably realistic flight simulator in which you can fly anywhere in the world! It’s a lot like the flight simulator function built into Google Earth, but you get an aircraft to look at and way better instruments. There’s even in-cockpit views. Go fly it!
