Given that the Malay PM has now put it on record that transponder and ACARS on MH 370 were disabled deliberately the disappearance of this aircraft and passengers now becomes a crime.
When police investigate crimes they may put some info out to the public and appeal for help but they never put all the cards on the table. ('keep the powder dry')
Of course there will be info about MH370 that authorities know which we don't (yet).
It is like trying to complete a jigsaw without all the pieces.
Thanks to posters here who are trying to make sense of the pieces we have.
Edit:
On 11 March it emerged that
the Boeing 777's diagnostic maintenance data messaging system, the Aircraft Communications Addressing and Reporting System (ACARS), had sent two bursts of data at both take off and during the plane's climb to cruise altitude. While this was the first sign that investigators had at least some forensic flight data to go on, no further ACARS reports were transmitted.
Now the investigation team thinks they know why.
"Based on new satellite information, we can say with a high degree of certainty that ACARS was disabled just before the aircraft reached the East coast of peninsular Malaysia. Shortly afterwards, near the border between Malaysian and Vietnamese air traffic control, the aircraft's transponder was switched off," Razak says.
In other words somebody who knew what they were doing - or who may have been forcing a pilot to do it - was trying to obscure the plane's position.
