MH370, which had been travelling from Kuala Lumpur to Beijing, disappeared on March 8, 2014, with 239 people on board. The Boeing 777 aircraft last communicated with air traffic control at 1.19am when the plane was flying over the South China Sea.Minutes later, it completely disappeared from civilian radar screens during a routine handover from Malaysia to Vietnamese radio channels.
Analysis of radar and satellite data shows it suddenly changed course and flew back across Malaysia before turning south of Penang and then towards the southern Indian Ocean.
Many theories have surfaced over the last few years, including the possibility, the pilot went on a suicide mission.
Simon Hardy, a former British airline chief pilot and aviation expert says he can prove Mr Shah flew purposely to avoid action from the military in both Malaysia and Thailand airspace.
In a new documentary with Australia’s 60 Minutes, he revealed his "remarkable discovery".
Mr Hardy said: “As the aircraft went across Thailand and Malaysia, it ran down the border going in and out of each county.
