Anyone who has had to meet someone at the airport can attest to the pain of waiting around for a delayed flight. But here is a cool site that allows you track not only one flight, but all flights by airline, aircraft type, departure, or destination airport. You can also look at the history of a specific airplane ‘tail number’ and see where it has traveled over the past few days. From a privacy point of view, that might not be a good thing, especially if you’re a private pilot and want to fly somewhere without your friends or spouse knowing. 🙂

They also have a cool animation of all aircraft traffic throughout a 24-hour period. Very interesting if you’re into aviation.
