Officials say possible debris from the flight has been found in the sea off Vietnam.

There was no distress signal from the aircraft and the Royal Malaysian Air Force says radar shows it might have turned back from its scheduled route.

Interpol says billions of passengers are boarding flights each year without their passports being checked against its Stolen and Lost Travel Documents database.

Neil Fergus is a security and counter-terrorism consultant and was one of the authors of the 2005 Wheeler review into aviation security in Australia.

He told Greg Dyett Interpol's head, Ron Noble, is only telling part of the story about passport screening.
