I understand that folks who drive in Los Angeles traffic like to look up the CalTrans real-time traffic information to "see" what freeway conditions are like. The freeway is 18 miles away and the nearest traffic signal is over 50 miles away so, I usually don't need that kind of information. From my vantage point high in the mountains, however, I see another kind of traffic information. Day and night, I see number of planes in flight corridors overhead at extremely high elevations. Although cannot usually hear them, I've often wondered where they were going. I don't have to wonder any more...
I've just found three web sites that allow me to watch air-traffic control flight data from a number of Southern California airports:
Los Angeles International Airport
Bob Hope (Burbank) Airport
Van Nuys Airport
This is an excellent use of JAVA and web technologies to display air traffic information in near real-time. (For security reasons, the flight data is delayed 10-minutes.) Air traffic controllers like to "see" what's going on in the skies overhead; now, I can too.
These sites offer an impressive visual display of flight data. While it's not quite Google Earth, it's impressive nonetheless. Try clicking on a plane to see the flight number and airline. You can also zoom in from 5 miles to 80 miles away. Apparently, there are plug-ins for Microsoft Flight Simulator that will bring in this data for even more realistic navigational adventures.
