Was wandering about the net looking for something to do while waiting for more used planes to hit the market in MT3 and stumbled across this.http://www.passur.com/airportmonitor-locations.htm
Thought it might interest some of you. You can choose from some US airports (JFK, BOS, BUR, and some others) and view air traffic for the airport. View live (delayed 10 mins for security reasons) or choose a date/time. Can see aircraft type and altitude. Flight ID, origin, and destination also viewable, just not live.
Sorry if all of you know about this already, or if it is re-post. I just thought it was kind of entertaining and thought it might be worth sharing.
