Malaysia's government and the British satellite company Inmarsat released on Tuesday the data used to determine the course of missing Malaysia Airlines Flight MH370

The move was made in response to mounting calls from passengers' relatives for greater transparency.

The data, comprising satellite communications with the plane, occupy 47 pages in a report prepared by Inmarsat. The information includes hourly "handshakes" - network log-on confirmations - after the aircraft disappeared from civilian radar screens on March 8, Reuters reported.
