A picture shows the offices of satellite operator Inmarsat in central London on March 25, 2014. Inmarsat said it managed to work out which direction the missing Malaysia Airlines plane flew in by measuring the Doppler effect of hourly 'pings' from the aircraft. Malaysia's prime minister announced earlier that the Inmarsat analysis of flight MH370's path placed its last position in remote waters off Australia's west coast, meaning it can only have run out of fuel above the southern Indian Ocean.
