Reports where that the pilot was not in his seat, this could indicate that the pilot was checking-out what was wrong with the aircraft.
The Greek Army denies speculations of the F-16 having shot the aircraft down because it did not respond to any calls and/or instructions that the ground and/or the F-16's gave to the pilots.

The aircraft crashed near the town of Marathon.
CNN reports that a passenger has send a SMS to a cousin in which the passenger claims that the pilot was back in the cabin and when he was back in the cockpit they both slumped and it was freezing in the aircraft.
Apparently the aircraft was flying on the autopilot. When the a/c entered the Greek airspace it did not have any communication with the Greek controllers. As it was approaching Athens, two F-16’s took off to intercept the aircraft. They could not see anybody in the cockpit but they reported someone standing in the cockpit with mask on. However, the a/c was still flying its scheduled course. After they passed Athens airport, the a/c banked to the left and descended in what seemed an uncontrolled crash into a mountain (not very high one) area north east of Athens.
Rescuers that have approached the area of crash reported that the a/c was destroyed to pieces, and that only the tail section was somewhat in one piece. There was a small fire in the area that is under control.
Horrible news....
