WHAT COULD HAVE HAPPENED?

A mid-air explosion: The lack of debris could be explained by it falling into Malaysian jungle.

A terrorist attack: Director of CIA has said terrorism could not be ruled out

Power failure: Possibly caused by deliberate cutting of power to communication instruments

Electronic warfare: 20 passengers on board were experts in this technology.

Hijacking: Radar data indicates the plane might have made a U-turn.

A pilot error: There is a chance of them in all air mysteries, claim experts

Structural failure: Possibly involving damage sustained by an accident in 2012

Pilot suicide: There were two large jet crashes in the late 1990s caused by this

Aeronautical black hole: Plane is stranded hundreds of miles from current search area

 

With technology tracking our every move, it seems incredible that a plane carrying 239 passengers could vanish into thin air.

Yet despite flight data recorders, location transponders and radio communication, the Malaysia Airlines Boeing 777 disappeared on a midnight flight out of Kuala Lumpur on Friday.

Experts are baffled by the loss of communication, with some putting forward theories of mid-air bomb explosions, disappearance into an ‘aeronautical black hole’ and an attempt at electronic warfare.

The mystery has deepened after reports emerged that relatives have been able to call the mobiles of their missing loved ones.

Professor William Webb, a fellow of the Royal Academy of Engineering, told MailOnline: ‘The phones definitely won’t be working. They’ll be underwater, out of coverage and by this time out of battery.
So there’s absolutely no way they could be used for triangulation’.

‘As to why they are “ringing” it’ll be the same as if they were out of coverage – in some cases it may ring before going to voicemail.’

Some reports claim the phones are just ringing and ringing however.

He added that the phones will only be ringing if they are ‘switched on, not in water, the battery is charged, and [they are] near a mobile cell site.’

This means that if the phones are genuinely ringing, the plane needs to have landed on land – not in the sea – and be in a location where there is cell service, rather than in the middle of a jungle, for example.

Meanwhile, the disappearance of the aircraft may be explained by a deliberate cutting of power to the plane’s communication instruments.

Dr Martyn Thomas from the Institution of Engineering and Technology, told MailOnline that he thinks a sudden decompression of the plane may have taken place and effectively knocked out the pilot and passengers – as well as the communication equipment.

In this scenario, the plane could have flown on using its autopilot without any human influence and ‘could be anywhere within about 2,000 miles’.

Another possibility is that the plane fell into an ‘aeronautical black hole’ in the region, according to Stewart John, an aeronautical expert and Fellow of the Royal Academy of Engineering.

Radar is used to track planes over land in inhabited areas but when planes venture over remote lands, such as the inner part of Russia or over the jungles of Malaysia, the only way of tracking them is the aircraft sending back information at regular intervals, he explained.

HOW ARE FLIGHTS TRACKED?

On board a plane there are cockpit voice and flight data recorders – the ‘black boxes’ – which each include a ‘pinger’ that sends a transmission up to 30 days after submersion underwater.

In the black box is an ASD-B flight transponder which, unlike the GPS in a car, broadcasts its location by sending information back to air traffic controllers every second.

Crews are also able to speak to their airline through discrete radio channels.

The missing aircraft was comfortably at a stage of flight when the pilot would have had plenty of time to report any mechanical problems to Air Traffic Control.

Black boxes on commercial aircraft also contain cockpit voice recorders which could provide some insight into what went wrong on that plane at 1am on Friday morning.

It remains a mystery why no one can make contact with the box.

Nevertheless, lets be positive and hope for the best.
