Critical days were lost in the search for MH370 because Malaysian authorities initially rejected evidence from a British satellite company that the Boeing 777 with 239 aboard was in the Southern Indian Ocean.
British sources told AirlineRatings.com Editor Geoffrey Thomas that within 24 hours of the disappearance of MH370 on March 8, Inmarsat, a satellite communications company based in the United Kingdom, advised the relevant Malaysian authorities of their findings but were rebuffed.
Inmarsat then approached the U.K. Air Accidents Investigation Branch (AAIB) with its data and it immediately recognized the significance.
Inmarsat was contracted to provide a data link to the Malaysian Airlines fleet and continued to get a signal every hour from MH370 till 8.19 a.m. Perth time.
The Malaysian authorities were forced to take the findings seriously when the AAIB teamed with Inmarsat to represent the data around March 14 - five days after the Boeing 777 disappeared.
