MH370 pilot devastated by his marriage breakdown,Not in the right state of mind to fly.

The pilot of doomed flight MH370 was distraught over his wife’s decision to move out of their family home and could have taken the plane for a ‘last joyride’ before it crashed into the southern Indian Ocean killing all 239 people on board, says a long-time friend of the pilot.
The friend, also a pilot, said Captain Zaharie Ahmad Shah had been left rattled by his family problems, and didn’t appear to be in the right state of mind to be flying. He warned that it was ‘very possible that neither the passengers nor the other crew on-board knew what was happening until it was too late’.

‘He's one of the finest pilots around and I'm no medical expert, but with all that was happening in his life Zaharie was probably in no state of mind to be flying,’ he told the NZ Herald on the condition of anonymity.

An aviation industry source, who wished to remain anonymous, told MailOnline: 'It was tracked flying at this altitude for 23 minutes before descending. Oxygen would have run out in 12 minutes [in a depressurised cabin], rendering the passengers unconscious.'

 The 777-200ER Boeing aircraft used on the ill-fated flight has a maximum service ceiling of 43,000 feet and can very probably fly safely at even greater heights, one expert said.
But at this altitude, where the atmosphere drastically thins, it would take mere minutes if not seconds for hypoxia - a lack of oxygen - to set in if the cabin was manually depressurised by one of the pilots, as seen in the below video of a high-altitude experiment.

 

Oxygen masks would have dropped down, but these only supply between five and 10 minutes of gas.
Central Queensland University's head of aviation, Ron Bishop, told MailOnline that a drop in cabin pressure that had knocked out passengers and crew would mean the plane would fly on unmanned until eventually running out of fuel and crashing into ocean.

‘You’d just slowly pass out. But it would have no effect on the plane at all,’ he said.
‘The plane would just keep going until it eventually ran out of fuel.
‘That would explain it all. That plane flew on a very long time, all the way from South East Asia to near the west coast of Australia.
The passengers' devastated families are expected to start arriving in Perth as soon as the debris is confirmed as belonging to MH370, with the Australian Government announcing it would set up a special facility to assist them, as well as waive any visa fees. -Culled
