It’s been more than four years since Google first added the flight simulator to Google Earth, and it remains one of the most popular features in Google Earth. As the quality of Google Earth’s imagery, terrain and 3D buildings have improved over the years, it’s helped make the flight simulator experience even better.
However, that wasn’t enough for user ‘that1anonymousdude’. He’s created a file that will modify your flight sim and let you turn the speed up really high. Using his mod, you can fly up to around 100,000 knots, while keeping solid control, and even fly up into space. It’s quite cool. Here’s a video of it in action:
His program modifies the flight sim config files to allow you to reach these crazy speeds (it doesn’t actually modify the actual Google Earth software). He’s released the source code so you can see how it works, and I’ve scanned it to verify there are no viruses or anything in it. However, always use caution when loading a third-party executable file on your computer.
