(CNN) – There is another wrinkle which could change everything investigators thought they knew about missing Malaysia Airlines Flight 370's disappearance.
Malaysian officials attempted to clarify a key part of the timeline Sunday.
At 12:41 a.m. local time, flight 370 took off from Kuala Lumpur, bound for Beijing. At 1:07 a.m., the Aircraft Communications Addressing and Reporting System, or ACARS, transmits data for the last time.
Just yesterday, Malaysian officials said they believed the ACARS system was shut off before the last verbal communication from the plane at 1:19 a.m.
But today, the airline's CEO is admitting that they don't know for sure whether it happened before or after 1:19 a.m.
As CNN's aviation correspondent René Marsh reports, that could make all the difference.
