We’ve always known that Google has wanted to challenge Microsoft’s desktop dominance in a number of areas, but to date we didn’t know that extended to gaming. Hidden inside Google Earth is a secret Flight Simulator that takes full advantage of Google’s extensive satellite imagery.
To access the hidden feature, open Google Earth and hit Command+Option+A (note it must be capital A) or Ctrl+Alt+A if you’re using a Windows Machine.
The Google Earth Flight Simulator comes with two aircraft options, a F16 Viper and the more manageable SR22 4 seater. Players have the option of commencing the game from their current location in Google Earth or can pick from a list of pre-determined runways. Control instructions can be found here.
