The flight engineer, Mohd Khairul, Malaysian, aged 29, had published days before on social networks, that he had worked for a Swiss charter company with private reactors (Execujet Aviation). This opens a question mark regarding whether he is involved in the disappearance of the aircraft.
Meanwhile, police have focused on their latest research a possible act of sabotage and kidnapping by some members of the crew, including the pilot and copilot.
Researchers believe that someone with deep knowledge of Boeing 777-200 and commercial navigation diverted the flight MH370 from its original route deliberately. For now, the main suspects of the possible sabotage are the pilot, Zaharie Ahmad Shah, 53, and copilot, Fariq Abdul Hamid, 27.
For its part, the Malaysian government requested last sunday the cooperation of governments such as Pakistan, Kazakhstan and Australia, to supply it with data from satellites and radars that allow trace the possible path traveled by the aircraft.
