Missing Malaysian Plane #MH370 Latest: Malaysia releases transcript of last words from missing plane

After more than three weeks, the search for Malaysia Airlines Flight 370 has come down to this: a lot of floating rubbish, hundreds of heartbroken relatives and, now, quibbling over words that everyone acknowledges offer no clues into what happened to the doomed plane.

Malaysian authorities on Tuesday released the transcript of radio chatter between air traffic controllers and the plane in the hour or so before it vanished while flying from Kuala Lumpur, Malaysia, to Beijing on March 8 with 239 people on board.

And while the transcript offers no clues about the plane's mysterious disappearance, one glaring discrepancy has highlighted criticisms of how Malaysian officials have handled the investigation.

The transcript shows the last voice transmission from the doomed plane was "Good night Malaysian three-seven-zero," not the "All right, good night" transmission authorities had previously used.

That authorities had given such an incorrect version earlier this month and allowed it to stand uncorrected for weeks undermines confidence in the investigation, air accident investigation experts told CNN.

"High criticism is in order at this point," said Mary Schiavo, a CNN aviation analyst and former inspector general for the U.S. Department of Transportation.

Malaysian officials have defended their work. Acting Transport Minister Hishammuddin Hussein recently said, "History will judge us well."
