What's new is that now, the map can toggle between 2D and 3D displays.
The 3D display is still very rudimentary : you don't have all the features you find in the 2D display, because both my scripts and the 3D google feature itself are beta releases. What I plan to offer in the next few weeks is a real 3D preview of your flight.
Yet, you see on this 3D display the airfields along your route, and sometimes your route appearing as an orange line on the ground.
You can't click on the 3D airfields marker, yet, to know which airfield they represent, but this should be possible shortly. (It is possible if you toggle back to 2D maps.
To know how to use it, click on the "help" link in the planner page.

The first time you'll use the feature, you'll have to install a google earth plug-in. You'll be prompted to do it.
I'd appreciate comments and suggestions regarding this new feature.
Here is what the 3D displays looks like: (Serre Ponçon lake, Alps, France):

Good flights.
