JFK Timetable tracker

I expect some of you know this already but the JFK online flight info board is linked directly to a flight tracker. It shows the height, speed and position of any aircraft using the New York airports.

If you click on the ‘Current Traffic’ button (top right) it shows all aircraft approaching or departing. Very neat.
