In case you're wondering about public access to these kinds of datasets: http://en.wikipedia.org/wiki/Automatic_dependent_surveillance-broadcast#Public_Access_to_ADS-B http://en.wikipedia.org/wiki/Automatic_dependent_surveillanc... According to the same Wikipedia article, the FAA is has been rolling this out since 2006 (target date of 2015 for full coverage).

It's not actually public access to "Data sets" - these folks are intercepting over the air live transponder data from each aircraft and then plotting the resulting information. There are two primary forms of these types of transponders, one basic which just transmits the aircraft altitude and unique identifier, and the other advanced which transmits location, altitude, heading, intent (lading, taking off, descending etc). In the United States, most aircraft only use the basic version, so actual plotting all aircraft using these interception techniques is much more difficult. However, any international aircraft that fly in the US, or aircraft that are international capable, can be tracked. There are out of the box commercially available receivers and software that you can use to get started... but again be warned that until US adoption becomes more widespread you'll only be able to track International flights.

  The code for a the basic (mode A/C) transponder isn't actually unique. It's just 4 base-8 digits settable by the pilot, with several codes reserved for specific uses. When on an ATC-assigned code, that code in only "unique" within a specific area. I might be assigned 0234 flying in Boston Center's airspace and someone else might be on 0234 in Phoenix.
