As the Malaysian government prepares to publish its interim report on the disappearance of flight MH370, there's fresh speculation as to what might have happened in the plane's final hours. The report is expected to confirm the conclusions of the British-based satellite company, Inmarsat, that the Boeing 777 crashed landed in the Southern arm of the Indian Ocean.

Somewhere in the vast waters of the southern Indian Ocean lie the shattered fragments of Malaysian Airlines, flight MH370. So, far the sea has refused to give up its secret. At Inmarsat headquarters in London, they remain confident their satellite positioning of the wreckage is accurate. The interim report on the crash from the Malaysian government expected to endorse that later.

"Inmarsat has always said that its model was a sound model based on the seven pings that came off between the aircraft and our network. We've also always said that unfortunately those pings didn't contain any GPS location data, as this plane didn't transmit location data and it also didn't have it's transponder switched on, quite deliberately switched off we understand," Chris McLaughlin, Inmarsat Senior Vice President, said.

As the massive, multinational hunt for the wreckage and the bodies of the plane's 239 passengers continues, the Malaysian government's report will fall short of attributing blame or motives for the tragedy.

There is increasing and alarming speculation inside the aviation industry that the data exists suggesting that whoever was in charge of Flight MH370 on that fateful took the plane up to 45,000 feet, way beyond the capability of a triple seven and then down to 5,000 feet below the radar in Singapore and then, possibly on cruise control, to this area here where the last ping was heard and the craft disappeared.

Malaysia's Transport Minister, Hishamuddin Hussein, will likely face reporters questions on the data when later he unveils the interim report into the crash. In the meantime the search for MH370 continues using a robotic submarine, a part of the earth less mapped than the dark side of the moon.

The searchers looking for wreckage now resigned to a hunt that could go on for months and possibly years.
