The Malaysian government has insisted that shah was mentally stable, was recently released in a 495-page report released in July 201
Shah's friends told The Atlantic that the 53-year-old pilot "was often lonely and sad." His marriage had dissolved and his children were grown and out of the house. Shah also customs friends spent the days between flights pacing empty rooms alone in one of his two homes.
He spent a lot of time contacting young women on Facebook, according to The Atlantic's report.
"He is known to have established a relationship with a married woman and her three children, one of whom was disabled, and to have obsessed with two young internet models, whom he encountered on social media, and for whom he left Facebook comments that apparently did not elicit responses, "The Atlantic reported.
The report also details why other stories on the flight's demise and disappearance don't make sense.
The Malaysian government and the Australian Transport Safety Bureau have theorized that an oxygen deficiency incapacitated the passengers and crew. Other theories suggest that electrical power brought down the plane or point to a potential hijacking from two passengers who had boarded the plane with stolen passports.
However, these theories don't explain why the plane traveled for hours on autopilot, the commercial-airline pilot and the author of the book "Cockpit Confidential" Patrick Smith previously customs Business Insider. He said the nature of the debris also suggested that the plane was under control when it crashed.
"It is inconceivable that the known flight path, accompanied by radio and electronic silence, was caused by any combination of system failure and human error," according to The Atlantic.

He described the mystery as a pyramid that is broad at the base and one man at the top, meaning that the inquiry might have started with many possible explanations but ended up with a single one. He said, "It doesn't make sense. It's hard to reconcile with the man I knew. But it's the necessary conclusion."
