Missing Plane MH370: Full Transcript Of Pilots' Final Conversations Released

Malaysian authorities have released the full transcript of the conversations between the pilots on missing Flight MH370 and air traffic control before the plane disappeared.

It said the transcript showed nothing "abnormal". But the newly released information contradicts a statement released earlier by authorities.

There was no explanation for the discrepancy.

The three-week hunt for Flight 370 has turned up no sign of the Boeing 777, which vanished March 8 with 239 people on board bound for Beijing from Kuala Lumpur.

The search zone area has evolved as experts analyzed Flight 370's limited radar and satellite data, moving from the seas off Vietnam to the waters west of Malaysia and Indonesia, and then to several areas west of Australia. The current search zone is a remote 254,000 square kilometre area that is a roughly 2½ hour flight from Perth.

Search coordinators warned the hunt could drag on for some time yet.
