What happened after that is almost a complete mystery.
Prior to reaching Vietnam airspace, the flight deviated and changed direction. Instead of heading north to Beijing, it headed south, crossing the Indian Ocean well away from landfall.
The search for the missing airplane became the most expensive in aviation history. Yet, despite scouring thousands of square kilometres of the South Andaman Sea, the South China Sea and the Indian Ocean, no sign of MH370 was ever found.
Geoffrey has been a voice of reason for both the public and the media, who turn to him for comment on aviation, in particular in Australasia.
In this podcast, we chat to Geoffrey Thomas about new evidence of the final route of MH370 that has been predicted using software designed and tested by aeronautical engineer Richard Godfrey, which suggests that the remains of MH370 are located 1,933 km west of the Western Australian capital, Perth.
Is it possible that we do know the final resting place of MH370? Geoffrey Thomas gives us compelling evidence that we may have pinpointed the correct spot and gives us his view of what actually happened.
