Cargo shifting on MH370 Boeing 777.

MH370 Boeing 777-200ER, blackout, accident.

Cargo shifting could cause a blackout accident on a Boeing 777, if the cargo is loose and not connected to the aircraft the cargo will break the wall to the power equipment center and kill the power.

MH370 max 10 pallets.
MH370 had 4 tons, pallets, of fruits on board, if it hits the wall to the power center it could break the wall and kill the power. It doesn't necessarily need to start a fire, it's just kill the power to the cockpit and it may also kill the connection to the battery backup power, the captain is hopeless.

It doesn't matter where you put the cargo if it's loose, it can start to shake lose under the take off, the cargo gonna end up in the rear of the front cargo space. Once the plane hits the right altitude, maybe the plane drops a little bit or slow down a couple of km/h the pallets gonna start to move toward the wall to the power equipment center and it will accelerate. If its 4 pallets it could be 4 smaller hits or if they come together 1 big hit.
  
 If the cargo starts to shift on an airplane, it becomes chaotic, anything can happen.

"Supporting an exclusive report in the Daily Mail last month which raised the question of whether an explosive device could have been planted in the cargo of four tons of mangosteens, Inspector-General Tan Sir Khalid Abu Bakar said the cargo was under investigation".

Boeing 777 front cargo
1 freight ton = 2000 lb = 900 kg, 900/2000=0,45
1 lb = 0,45 kg.
16/2x0,45=3600 kg
Front cargo space max = 3600 kg
MH370 front cargo space had 4000 kg of fruits on pallets.
MH370 was overloaded in the front cargo space.



If the load is not secured properly in the aircraft, it becomes very dangerous.
It will slide down at the end, up in the rear in the front cargo space when the jet plane takes off. 
If the cargo is loose at the rear of the front cargo space when the jet plane hits marsh-speed and right altitude it doesn't need much to make it start to roll forward and hit the wall to the power equipment center, an air pocket is enough.

The power equipment center is on the other side of the front cargo space.

The ATC system is placed on top at the aircraft and got it's own battery backup, so it continue to send signals to the satellites even thou it is a blackout in the cockpit.

..............MH370 Boeing 777-200ER, blackout, accident....................

The power is gone so the captain don't see anything.

MH370, Boeing 777-200ER, blackout, accident.

The captain is not on his way to middle of nowhere, he is on his way to Perth. The blackout in the cockpit kills the navigation, communication and transponder and it's dark! He goes up in hight first so he don't hit another plane(nobody can see him), he spend some time checking what's wrong, he can't find it, what to do in the dark with maybe only a analogue compass, very difficult.

The captain decides to go back to find the landing track, he drop the plane to 3600 meter but he don't see any light's on the ground, cloudy and dark. So the captain decides to go towards Perth where the sun is going up earlier and he knows Perth, Malaysia Airlines flies there every day and the captain had over 18.000 hours in the air so he been there before.

When the fuel is gone the captain try to sliding land on the water, that's why there are so big debris, crash landing no big debris, higher speed!
The captain missed Australia with approximately 5 degrees.

Blackout!

A blackout is when electricity is lost to the navigator, communications and transponder, you do not know where you are anymore, and no one on the ground knows where you are, motor and control system works, it does not necessarily mean that there must be a fire hazard. The reason may be cables, switches, fuses, power supply-generators, battery backup, which of them is hard to say since I'm not familiar with the electrical system in the plane.

1. I do not think they lost all power systems (batteries and generators), but they lost power to the cockpit.
2. That all blown fuses at the same time, I don't think so.
3. Cables: perhaps, may have lost the + or - voltage to the cockpit 28 volts DC.
4. Switch: if one generator fails, electricity needs to come from somewhere else, I doubt that everything is running at the same time (generators and battery backup) then there must be some kind of switch between the power supply and battery backup so they can not affect each other .
What caused the malfunction can be; maintenance, service, manufacturing defects, design defects-that's occur with shifting cargo.
It's not the captain's fault, he tried to resolve the situation in the best way, I had thought and done just as he was after I thought a lot longer, than the time the captain made hes decision on.
