Seven months after the Malaysian airline flight 370 went missing without a trace, the mystery surrounding its disappearance is no closer to being solved.

Until now, the most widely-held belief is that some sort of incident occurred onboard, causing the plane to be placed on autopilot until it finally crashed into the Indian Ocean, but this theory has now been dismissed by the boss of Emirates Airlines, Sir Tim Clark, who has said he thinks it extremely unlikely that the plane was lost in this way.

As the search for the lost plane resumes in the Indian Ocean after a four month break, Sir Tim has questioned the validity of this action, saying that there is nothing to suggest that the plane went down into the water. If this had been the case, then it would be highly unlikely for there to be no trace of any wreckage or debris.

“Our experience tells us that in water incidents, where the aircraft has gone down, there is always something," he said.“Every single second of that flight needs to be examined up until it, theoretically, ended up in the Indian Ocean – for which they still haven’t found a trace, not even a seat cushion."

The search was originally steered in this direction by an apparent "satellite handshake, " a final unexplained signal emitted by the missing Malaysia Airlines plane which was tracked to a point in the Indian Ocean. It was believed that this final "half-handshake" – or satellite contact – could have signalled the moment at which the plane ran out of fuel and plunged into the Indian Ocean.

“We have not seen a single thing that suggests categorically that this aircraft is where they say it is, apart from this so-called electronic satellite ‘handshake,’ which I question as well,” added the experienced airline chief.

Sir Tim’s comments have once again stirred public interest, as he has stated that “MH370 was, in my opinion, under control, probably until the very end”.

He is requesting that there be greater transparency in the investigation, as he believes that the identity of the passengers or even its cargo could hold the key to the plane’s disappearance. For such a large passenger plane to vanish without a trace in an age of advanced technology is totally improbable and highly suspicious.

“I’m totally dissatisfied with what has been coming out of all of this,” he said, adding: “We need to know who was on the plane in the detail that obviously some people do know. We need to know what was in the hold of the aircraft.”

The fact that the plane’s advanced tracking device appeared to have been disconnected or disabled has only added to Sir Tim’s suspicions:

“Disabling it [the tracker] is no simple thing and our pilots are not trained to do so. But on flight MH370, this thing was somehow disabled, to the degree that the ground tracking capability was eliminated.”

The debate over its whereabouts continues, but without a single shred of evidence, the mystery is as inexplicable today as it was on the day the plane apparently evaporated into thin air, along with its 239 unfortunate passengers. It is becoming one of the most unfathomable airline incidents of its time, as although other planes have disappeared without a trace, including the enduring legend of ace pilot Amelia Earhart, who disappeared in her twin-engine monoplane over the Pacific Ocean in 1937 during an attempt to circumnavigate the globe, most such disappearances were decades ago before sophisticated satellite tracking and radar systems were used.

A succession of lost ships and planes do still occur with reasonable frequency in the so-called "Bermuda Triangle," a triangular area of open ocean located between Bermuda, Miami, Florida and San Juan, Puerto Rico. Records compiled by Bermuda-Triangle.org indicate that around 129 planes have disappeared over the waters in the Bermuda Triangle between 1945 and 2008, though none of these were of a comparable size to flight MH370.
