Ten countries are involved in the search for missing Malaysia Airlines Flight 370. The Boeing 777 disappeared last Friday carrying 239 passengers.

What Could Have Happened to Flight MH370?

Military radar shows the plane went farther off course than originally thought. The transponder signals were disabled, which normally send data on altitude, direction and speed.

Investigators are also looking into the pilots’ backgrounds amid reports of one pilot inviting Australian women to sit in the cockpit during a flight a few years ago.

Jonti Roos said that throughout the flight, the pilots were smoking and taking photos with them.

The CIA director has not ruled out terrorism. The two Iranian men who used stolen passports on the missing flight were said to be seeking asylum in Europe.
