MH370 Data Leaves Many Unanswered Questions

It is 47 pages which are supposed to satisfy the families of the missing Malaysia Airlines aircraft about the fate of their loved ones.
But soon after its publication both the families and aviation analysts scouring the details said the information added little that was new.
And what's more it lacked the finer detail enabling other experts to give their own independent assessment of the data.
The lion's share of the information released relates to data from MH370 while it was still on the ground in the Malaysian capital Kuala Lumpur.
It goes on to give information about the electronic pings or 'handshakes' received from the aircraft after its ACARS communication system was switched off shortly after it took off for Beijing.
Aviation analysts say one of the so-called pings - at 11.41pm on the night the aircraft disappeared - is omitted from the data.
We don't know why.
They also say that additional data giving the exact position of satellites and their distance from the aircraft have not been released.
It is this kind of detail which makes further interpretation by others difficult.
And that's something which has been leapt on by the families who have called for all information known to authorities to be released.
This data was known within a few weeks of the aircraft's disappearance on March 8, but it has taken until now for it to be released.
A team of international experts used the satellite data along with other information such as radar data and engine performance calculations to reach their conclusion.
But it's not clear why it's taken until now for the basic data to be released.
Inmarsat, the British satellite company which provided the ping data to the Malaysians, said they were unable to release information without the authority of the Malaysian government.
The Malaysian government concluded within a couple of weeks of the flight going missing that it had ended in the southern Indian Ocean.
Steve Wang, a relative of one of the missing Chinese passengers, said: "What we want is the full version of the information including all the data and how it is calculated.
"Data on its own means nothing. The data leads to a conclusion not an ending."
Sarah Bajc, whose partner Philip Wood was on the missing plane, said she was "annoyed" that Inmarsat and the Malaysian authorities hadn't released everything they used to reach their conclusions.
She said: "I see no reason for them to have massaged this before giving it to us."
Communications expert Mischa Dohler says there are still many unanswered questions - and there is still information to be released.
He said: "I don't think this specific data will help in the search for the aircraft. It is important we find the plane but we may never know what happened."
