This cool tidbit by way of wise, totally plugged-in
Joi Ito's blog."This may be old news, but I just saw
FlightAware for the first time. It tracks flights in the US that the FAA manages including general aviation. You find a private plane and then drill down to past flights that the plane has made. Quite amazing. I wish they could do this internationally."According to
FlightAware's website, "offer free flight tracking for both private and commercial air traffic in the United States." It's a slightly technical feeling interface, but it provides tons of interesting information.
