• 3) Only the transponder signal of MH370 disappeared from the ATC Controller radar display whilst the (radar) position symbols from other aircraft were still available.

• 5) It could not be established whether the aircraft was flown by anyone other than the pilots.


• 6) The reconstruction flight conducted on the B777 flight simulator had established that the turn back was likely made while the aircraft was under manual control and not the autopilot.

• 7) The aircraft primary radar target was designated as ‘friendly’ by the Royal Malaysian Air Force as it did not pose any threat to national airspace security, integrity and sovereignty.
