Various countries are still searching for the missing Malaysian Airlines flight MH370, meanwhile, an online live flight tracker becomes more popular these days as it displays all the flight routes in live.
You could zoom into specific region, and mouse click the icon to see the flight information (e.g. airline company, aircraft, departure city & destination, estimate flight time, speed). The flight route would also be shown on the map.
This map is not only a live flight tracker, but is also a flight tracking system that you could playback the world map with all flying flights by selecting specific date and time.
Though there is not category legend for selecting displayed information on the map, there is still a filter feature for filtering.
Please note two types of flights are being pinned on the map, real time flight and flight with 5 minutes delay, that you can refer to the map legend for the indication.
