Well due to the fact that I'm obsessed with ATC and airline fleet scheduling and the like, I'll admit to tracking flights and aircraft obsessively. The best is tracking an airline's aircraft using electronic timetables and flight info to check gates and follow an aircraft around for a few days. Plug the flight #s for a particular aircraft into Fboweb's flight tracker and watch it for days. And the fact the I pay for that doesn't make me look much less dorky either. Also fun to listen to a flight departing on one of the feeds and hear in on approach and tower on teh other end for flight originating and arriving airports that have feeds. Yeah...I'm over the top. Going to stop before I embarress myself.
