5. The Flight
(...)
Up to the last position report point, transmitted automatically via the ACARS messages, the airplane had not deviated from the planned route by more than 1 nautical mile. A possible alteration of the route, as made by other flights crossing the area at the same period of time, could only have happened in the last 5 minutes of the flight.
