With the confirmation of MH370 crashing, suicide angle into the mystery heightened as sources told The Telegraph that the crash seemed to be deliberate.
According to a report from The Telegraph, officials investigating the scenario said that there was malfunction or fire that would have caused MH370's communication system to be disabled before it changes its course.
The unnamed official told The Telegraph that all information retrieved about MH370's routing, signaling and communication proved that the plane was indeed maneuvered "in a rational way."
"This has been a deliberate act by someone on board who had to have had the detailed knowledge to do what was done ... Nothing is emerging that points to motive," the official said.
Pressed about the possibility of malfunction or fire on board, the source insists it did not make sense.
"It just does not hinge together... [The investigators] have gone through processes you do to get the plane where it flew to for eight hours. They point to it being flown in a rational way."
To make the mystery more confusing at this point, Malaysia Airlines, through its statement said that "prayers go out to all the loved ones of the 226 passengers and of our 13 friends and colleagues" - while days after the news broke, passenger manifest reported 227 passengers and 12 crews.
MAS had not responded to the inquiry about the discrepancy.
According to Inmarsat's, even with MH370's communication system shut off after the plane' disappearance on March 8, its satellites had been receiving hourly pings from MH370. Data retrieved from these pings proved that MH370 had been flying for at least five hours after it was "lost."
Chris McLaughlin, Inmarsat spokesman described its data analysis as "ground-breaking math-based, peer-reviewed process revealing a direction of travel".
In an interview with CNN, Mr McLaughlin explained the process used was likened to a Doppler effect.
"Effectually, we looked at the doppler effect, which is the change in frequency due to the movement of a satellite in its orbit. What that then gave us was a predicted path (of the aircraft) for the northerly route and a predicted path the southerly route. What we discovered was a correlation with the southerly route and not with the northern route after the final turn that the aircraft made, so we could be as close to certain as anybody could be in that situation that it went south. Where we then went was to work out where the last ping was, knowing that the aircraft still had some fuel, but that it would have run out before the next automated ping. We don't know what speed the aircraft was flying at, but we assumed about 450 knots."
Prime Minister Datuk Seri Najib Tun Razak confirmed in a press conference Monday that the missing Malaysian Airlines MH370 ended in Indian Ocean, west of Perth. His announcement was based on conclusion made by British investigators, Inmarsat.
"Based on their new analysis, Inmarsat and the AAIB have concluded that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth. This is a remote location, far from any possible landing sites. It is therefore with deep sadness and regret that I must inform you that, according to this new data, flight MH370 ended in the southern Indian Ocean," the Prime Minister said in a statement.
