"Good night, Malaysian three seven zero," these were the last words of Zaharie Ahmad Shah, the captain of Malaysian Airlines Flight MH370, on March 8, 2014.
Shah who was commanding the Boeing 777 that had 227 passengers and 12 crew members said these words as the flight was leaving the Malaysian airspace and was entering Vietnam on its way to Beijing.
Moments after this now infamous good night MH370 disappeared from the radar and for the past ten years, the world has been searching for it.
Many including the Malaysian government have hinted that they suspect the involvement of Captain Shah in whatever happened to MH370 on March 8, 2014.
They argue that a Boeing 777 just cannot disappear into thin air, without the expertise of a seasoned pilot like Shah.
Investigations have revealed that MH370's tracking devices were purposely turned off by someone from inside, to make it disappear from the radars.
For many, this makes Captain Shah, a veteran pilot with Malaysia Airlines since 1981 and more than 18,000 hours of flying experience, the prime suspect.
They have argued that Captain Shah turned off the tracking devices between the Malaysian and Vietnamese airspace and took it off-course.
It is believed that MH370 turned back to Malaysia carefully avoided detection by military radars, and flew all the way into the Southern Indian Ocean, where it crashed after running out of fuel.
Satellite data from Inmarsat showed that MH370 last contacted its satellite over the southern Indian Ocean, where it had no reason to be present.
What makes the pilot mass-murder-suicide theory even more compelling is the data from Captain Shah's home flight simulator.
During the investigation, authorities recovered a hard drive containing data from his flight simulator. It showed that Captain Shah had flown a Boeing 777-200 on a path similar to that MH370 is believed to have taken on that fateful day on his simulator.
It is suspected that Captain Shah medically planned his operation and routes on the simulator before executing it on March 8, 2014.
