There’s new focus on the pilots of missing Malaysia Airlines Flight 370. Malaysian officials said over the weekend that the jet that vanished over a week ago carrying 239 people was likely hijacked.

Investigators are now searching the homes of pilot Zaharie Ahmad Shah and co-pilot Fariq Abdul Hamid.

On America’s Newsroom, Congressman and chairman of the House Committee on Homeland Security Michael McCaul (R-TX) said he believes the disappearance is an intentional and deliberate act.

He does not think the plane headed north toward Kazakhstan because there are many military systems near Afghanistan, including Bagram Airfield, that would have detected it.

After speaking to experts, he said it’s more likely Boeing 777 headed toward Australia, and is somewhere in the Indian Ocean. Australia has joined the list of countries searching the ocean for the plane.

Malaysia Airlines said that the co-pilot, Hamid, uttered the final communication heard by air traffic controllers. He said, “All right, goodnight,” after one of the communications systems had been switched off.

Investigators have not ruled out pilot suicide as a possibility. Regardless of whether it’s terrorism or suicide, McCaul said two scenarios are possible. “One, it ran out of fuel and crashed in the Indian Ocean. The other one, the plane landed somewhere in Southeast Asia, possibly Indonesia, that could be later used as a weapon.”
