KUALA LUMPUR: Malaysia’s aviation authority released on Tuesday satellite data used to determine that flight MH370 went down in the southern Indian Ocean following demands from sceptical relatives of those on board. The Department of Civil Aviation (DCA) said in a statement it had worked with Inmarsat to provide 47 pages of data communication logs recorded by the British satellite operator as well as explanatory notes for public consumption.

Family members of the 239 people on board the Malaysia Airlines plane, which vanished on March 8, had demanded that raw satellite data be made public for independent analysis after an initial undersea search found no wreckage. AFP was not immediately able to interpret the highly technical numerical data, which used the Doppler effect — the change in frequency of waves from a moving object — to decipher the Boeing 777’s final flight path.
