Malaysia Airlines: The pilots of the missing plane; involved in 'deliberate action?'

(CNN) -- "All right, good night."

Those are the last words heard from the cockpit of Malaysia Airlines Flight 370, said Zulazri Mohd Ahnuar, Malaysian civil aviation officer.

Who said them? Was it the captain or his first mate? Or someone else in the cockpit with them?

Since MH 370 went missing Saturday, there have been more questions than answers, including about the pilots.

Did the pilot have a plan?

 

 

What happened in the cockpit of MH370?

 

 

Malaysian investigators are refocusing their attention on the passengers and crew. They now believe that the plane's diversion was a matter of deliberate action by someone onboard.

Information from international and Malaysian officials indicate that the Boeing 777-200ER passenger jet may have flown for more than seven hours after last contact with the pilots.

The duty of all pilots is to aviate, navigate and communicate, in that order, an aviation expert has told CNN.

Someone may have kept aviating, but either they couldn't -- or wouldn't -- communicate.

This is what we know about the 53-year-old pilot captain and his 27-year-old first mate.
