Here's an interesting theory...
Flight MH370 didn’t just "disappear": Historian suggests mystery was first case of remote skyjacking and 'was diverted to prevent delivery of secret cargo to China'
Norman Davies, a historian and author, believes one possibility could be that the plane, a Boeing 777, could have been glided for several hours and landed in Antarctica - the perfect hiding spot, where it could be buried beneath the ice sheet for decades.
But the technology on board, designed to stop a repeat of the 9/11 terror attack by allowing it to be controlled on land, could mean the disappearance of MH370 may be due to the first recorded case of a remote skyjacking.
"The missing Malaysian Airlines plane was fitted with one of these Honeywell devices. In other words it was capable of being taken over remotely. Is this what happened? I am not an expert, but there are conclusions you can draw as to what may have happened."
Norman said while we do not know what happened to the plane, its fate may represent a new and terrifying move into a form of cyber warfare that could be disastrous in future.
He claims it may have been remotely controlled because it had something considered valuable on board that whoever seized control did not want to get to China.
Norman believes there are three key facts that point to the possibility of the first recorded case of remote skyjacking - not once but twice. Mysteriously very little information has also been released about who exactly was on board.
He says: "The plane moved in three distinct phases. Everybody agreed that the plane was diverted deliberately by someone with an expert knowledge who not only turned off the transponder but also reset the on-board computer. It fact it then turned round and headed in the opposite direction.
"As soon as it was diverted it flew back over Malaysia , obviously under very close control from someone.
"Then in the second phase, as it flew over the Andaman Sea, whoever had been controlling it appeared to lose control and the plane started flying round in circles.
"And in the third phase the instruments suddenly returned and the signals showed the plane was functioning and cruising for around five hours. But they don't know in which direction.
"My suggestion is that it was remotely hijacked - twice. If it had been hijacked just once, for example by the Americans which is just a guess, to stop it getting to Beijing, it would have been flown to an American base.
"But that didn't happen. The logical conclusion is that a second hijacker gained access to the plane, in order to confound the aims of their adversaries.
"We do know the plane crashed, as pieces of the aircraft have been found. But the question is what was going on in those two to three hours?"
