I stumbled upon an interesting post today where a guy explains how those online flight trackers actually work.

It's a pretty technical article (this guy clearly knows what he's talking about) but worth a read. In a nutshell, he says that the way online flight trackers work is by tracking a plane's proximity to the satelites they use for in-flight phone calls and internet. This is similar to triangulating the location of a cell phone based on signals from radio towers.
