Inmarsat, using some very clever mathematical modelling, deduced that the frequency of the waves were changing in a way that gave away the plane's locations.He noticed how wave frequencies changed as an observer moved around the source.There's lots of flammable stuff in planes so you cannot fail to act.‘It is all pointing to suicide by someone on board - whether that is one of the pilots or somebody else on board.‘They were flying in a controlled manner and somebody switched off the communication equipment.’However, Mr Moody, who lives in Chilworth near Southampton, Hants, believes the public have not been told the full story.

This, included in a warning by Boeing that said corrosion might occur on some models of the jet, might account for the pilot on another plane hearing the mumbled voice of Fariq over the air waves.

This condition, hypoxia - oxygen starvation - might have led to the pilots fumbling with the controls, making mistakes and being unable to issue a MAYDAY before they passed out, turning MH370 into a ghost flight.

Mr Moody said: ‘What I will say is that some agency knows something more than what they are letting on and I have experience in this.‘It took 11 years to find out how Boeing was able to ring a ground engineer in Jakarta who got to us after about 15 to 20 minutes after landing.‘A phone call was made just when my engines started going wrong.

If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware.

This would have been a complex scheme that would require a computer genius with a knowledge of that particular aircraft's controls - but why use those seemingly impossible skills to send the plane off on a flight to nowhere?

The pilot of the infamous 1982 British Airways Flight 9 incident today said he believed the Malaysian Airlines MH370 was brought down deliberately.

Eventually, the flight made an emergency landing at the Halim Perdanakusuma Airport in Jakarta, Indonesia.

Even though he was behind the controls, he still didn't find out the full account of what happened until declassified files were released 11 years later.

Solution: Inmarsat's scientists analysed the faint pings from MH370 using a technique based on the Doppler effect, which describes how a wave changes frequency relative to the movement of an observer, in this case the satellite.
