The mystery of the missing Malaysia Airlines plane is deepening as authorities scramble to find solid clues into its whereabouts.
Authorities are looking into the background of one of the passengers of flight MH370.
Mohd Khairul Amri Selamat described himself on social media sites as a flight engineer working for a Swiss-based private jet charter company.
The 29-year-old’s apparent experience means he would have knowledge of in-flight computer systems.
However, as an engineer of executive jets, experts have said he would not necessarily have had the skills required to divert and fly a Boeing 777.
A senior police official admitted: “The focus is on anyone who might have had aviation skills on that plane.”
At this morning’s news conference Malaysia’s Transport Minister said: “All ground staff who worked on the plane are being investigated as well as the pilot and co-pilot.”
Investigators say that the plane, which allegedly had 239 passengers on board, could have landed at hundreds of locations.
It has been claimed it could have landed at one of more than 600 runways spread across at least a dozen countries, with some of the places being remote and inaccessible. Possible locations include Kazakhstan and Australia.
Michael McCaul, the chairman of the House Homeland Security Committee, said US intelligence was focusing on the two pilots, Captain Zaharie Ahmad Shah and his first officer, Fariq Abdul Hamid.
McCaul also suggested that hijackers may have landed the plane and be planning to use it “as a cruise missile” in a 9/11-style terror attack.
The search for the plane has dramatically widened as satellite data suggests the Boeing 777 flew for at least seven hours – more than six hours after it lost contact with air traffic control.
