Accuracy of inbound track
The FlightAware track shows, about 20 nm north, a jog to the right, presumably to get lined up for final. However, the new track didn't quite line up with RWY 18. Rather, it would have led them slightly east, crossing RWY 24 near its touchdown zone.
Any ideas on why this error? Is this measurement error in FlightAware data? (It does appear, however, to show the crash site accurately.)
