A look at what we know so far about missing Malaysian Airlines Flight 370


KUALA LUMPUR, Malaysia (CNN) - Many questions surround flight 370's communications systems.

We thought one of them - known as ACARS- was switched off by the pilots, but maybe not.

The confirmed timeline looks like this:

Flight 370 takes off at 12:41 a.m. Acars is transmitting normally at 1:07 a.m.

At 1:19, the final words from the cockpit, "all right, good night", were received by air traffic control.

"Sir can you tell us what you're doing inside the house?"

That lead investigators to believe both Acars and the plane's other main transponder were purposely turned off, and it focused suspicion on the pilots.

"These movements are consistent with deliberate action by someone on the plane."

But Monday, the CEO of Malaysian Airlines told us flight 370's ACARS systems might have been functioning and weren't supposed to transmit data again until 1:37, well after the pilots reported everything okay.

The aircraft's last ACARS transmission was 1:07 okay? We don't know when the ACARS was switched off after that. It was supposed to transmit 30 minutes from there another transmission, but that transmission didn't come true.
