Kuala Lumpur, Malaysia (CNN) -- They were words heard around the world as investigators searched for the missing Malaysia Airlines plane.
Weeks ago, Malaysian authorities said the last message from the airplane cockpit was, "All right, good night."
The sign-off to air traffic controllers, which investigators saidwas spoken by the plane's copilot, was among the few concrete details officials released in a mystery that's baffled investigators and drawn global attention since the Boeing 777 disappeared with 239 people aboard mid-flight on March 8.
There's only one problem. It turns out, it wasn't true.
On Monday, Malaysia's Transport Ministry said the final voice transmission from the cockpit of Flight 370 was actually
"Good night Malaysian three seven zero."
