Have you ever wondered where that jet flying overhead was going? Well, if you have an internet connection, you can find out. A site called flightradar24 mashes live flight data with a Google map giving an amazing, live map of every flight in the sky. Click on any jet icon and see, among other things, the plane’s speed, location, altitude and destination.
If you have the Google Earth plugin installed on your browser, you can even click the 3D button and get a live, flight-simulator view from the plane’s cockpit. Pretty neat.
