The investigation of Malaysian Authorities on who is behind the mysterious disappearance of Flight 370 has gone a full circle four months after the Boeing 777 jet left Kuala Lumpur for Beijing with 239 people on board.
During the first week of the disappearance, one of the prime suspects being considered then was Captain Zaharie Ahmad Shah. Among the speculations was that he did it in sympathy for Opposition leader Anwar Ibrahim, his friend, who on March 7 - the day before the plane left Malaysia - was sentenced by a court to jail for sodomy.
Among the evidences then believed to have bolstered the theory that Zaharie hijacked his own plane were flight simulators found at his home in Malaysia.
The captain being regarded again as a prime suspect, after other theories such as mechanical failure and terrorism were studied but ruled out, is premised on authorities proving that human intervention was involved in the aircraft's loss.
Among the basis of Zaharie being a prime suspect again are his lack of future plans, the presence of flight simulator programmed with a plan in the area of the southern Indian ocean, capped with the landing on an island with a small runway and deleted drills from his computer recovered by experts.
The captain's sister, Sakinab Ahmad Shah, insisted in an interview with Channel News Asia that he masterminded the disappearance of the jet.
She said, "We couldn't figure out why somebody who would want to commit suicide would prolong the agony of flying for four , five, six hours just to land there."
Sakinab stressed, "He was just a man who took so much to aviation. He loved aviation, he spent a lot of his funds buying model airplanes. If he could, I think he would attach wings to himself and fly - he loved flying that much."
