View 3D representation of active flights in US in near real time. With this KML, one can check out flight status, see flight tracks, and even play back animations of flights in 3D.
The data is roughly 15 to 20 minutes behind the current time, due to FAA restrictions. However, this is an excellent tool to get a look at all of the current flights in the US.

By hovering on a plane, you can see the flight number and a path of their journey to that point. Clicking on a plane gives you more information about the flight, including an option to view the full path of the flight as a KML tour. Opening the tour will show your plane with a larger red icon, and it will fly the entire path of its journey to that point.


...a new, dynamically updating KML file of commercial flights over the U.S. Turn on the layer to see the current location and altitude of thousands of flights, in near real-time. The KML file is created from data available on the Flightwise website, which they collect from the FAA every few minutes.
