It is telling me that a flight from Detroit to Tokeo (dl275) that departed at 12:10 pm has already landed and so it is longer tracking it. It is now 5:45pm. Well, maybe they mean it has crashed because not even sound travels that fast. In fact, it will not land until after midnight. This us a useless app. But they already have their money from me so I guess they are pretty smart because they produce junk, charge extra to lookup a flight, and yet they continue to make money from selling it. I set a filter to only show 747-400s from dtw. But it doesnt filter anything at all.
