Does anyone know how accurate the FlightAware data is and where it actually comes from? The last two data points for the accident aircraft have very slow speeds of 109 and 85 knots. Although the altitude still reads as one or two hundred feet I'm wondering if the aircraft was actually on the ground at that point and was sliding to a stop, or if they were airborne and stalling, or if the data just isn't good enough to be drawing any conclusions from it at all.
This is the data I'm talking about
