I had another look at the FlightAware altitude data Mark, and noticed there was a 162ft/min descent rate on one of the transmissions when they took up a westerly heading. As the location where this happened is right on the edge of our reception range, I would presume that the last data transmission we received was the 162ft/min descent, and our software then predicted the descending westward track until timeout. I noticed on our live map that the aircraft did drop off a couple of times.
