It is about 0120 at night when the MAS370 ceased transmitting its ADSB/transponder code.
At that time, there are three other aircraft in the vicinity although not that close. The two CES flights are the closer. I have estimated the CCA flight position because the ADSB signal was lost between 1715z and 1730z. I have drawn a line to the oil ring for reference. The CCA is in the same situation of the MAS370: About one hour into the flight and likely passengers are eating after the departure from SIN.
If we consider the distance and position (white blocks) between these aircraft, I believe that an in-flight explosion of the MAS370 would have been noticed by either crew members and/or passengers on board. I think that the Malaysian authorities will ask to these crew if they have noticed or not something.
We all hope that, for the manifestation of the truth, the aircraft will be located and the boxes recovered. Correct me if I'm wrong:
-The wreck is in the international waters, the country in charge of the inquiry is the state of registration of the aircraft.
-The wreck is on the ground or in the sea bed inside the jurisdiction of a country then this country is in charge of the inquiry.
Finally does Malaysia has an investigation bureau with the technical possibilities to open and exploit the data inside. The NTSB in one of its statement said that he was waiting to know what country would be in charge.
