Somebody didn't pay attention in high school chemistry class, either.

But this plane flew for an additional 7.5 hours.



Isn't this about how much fuel it had left to run? I'm sticking with my theory about one of the pilots killing everyone else, re programs auto pilot somewhere, kills himself, auto pilot runs out of fuel and crashes.

I'm sure it was a fire or electrical issue.

Our systems are shutting down. but, "Have a good night Malaysia" is the response they give instead of alerting them of an issue?

The fire and electrical problem has become comical. If something was wrong, they would have stated that and not said "Good Night"

So we got a split between the fire guys vs. non-fire guys?

You can sit here and try to be a smart arse or you can read the information I have given.

But since you are slow let me start from square one and break it all down again.


1. Fire in THE COCKPIT!! Cockpit does not mean the passenger compartment, it means the cockpit, where the people who fly the big flying machine sit.

2. Electrical fires are generally more smoke than flames. In a plane you use Halon to extinguish flames. Halon.

3. In a plane the relative pressure is kept around 6-8,000 feet. The O2 levels are less than what an average person is used to, and if you lifted weights or ran on a plane, you would quickly tire out. So take into consideration there is less pressure in a cabin. Now the level of oxygen itself is a constant in the atmosphere but at higher altitudes our bodies have a much harder time processing it. As does fire.


4. With the set o2 levels in the plane, and in the cabin. The pilot would use the Halon to fight the fire in the cockpit. By doing so the O2 levels would drops so wearing a mask would make sense. Also Halon gets you high, and you don't want a high pilot after the fire is out.

5. The o2 that comes out of the masks in the cabin is at a very very low pressure and is enough to breath, but if the fire is so bad in the passenger compartment that the use of the masks (remember the masks only flow once they are pulled down, there is no O2 flow as they hang) is fruitless at that point, and everyone is doomed anyway.

6. So you see if you have a fire, Halon will be in use anyway. As a last ditch effort to save the plane in the event of a massive fire in the cockpit, venting the cockpit with Halon is an option. As the pictures of the panel I provided earlier show the fire suppresion system, you can see that the 777 has many built in fire fighting features.

All I had said, and you still cannot grasp, is that Halon can be used to clear the fire out of a small area by robbing the fire of the chemical properties it needs to burn.
The misconception with Halon )mostly due to the Movie T2) is that it kills you to inhale it. It does not. But If smoke is in the cabin, then the best option would be to provide the passengers with pure oxygen. Yes provided them with pure oxygen .

As it's smoke and smoke may come from fire, but smoke =/= fire.
So again, the pilots could have flooded the cockpit with halon and if smoke was an issue provide the masks for the passengers.

Wouldn't they know the transponder went down? Because the "Goodnight" came after the transponder went down...

and the fire took out radio and all comms in the exact moment they were to contact Ho Chi Minh city?

No transponder wither, no back up radio system?

I can't buy the fire theory.

Riiiiight. Have you seen any video of pilots in the simulator. When the simulator goes off, there is a siren that goes off in the cockpit and you must push a button to turn that noise off.

The only thing that confuses me, is why didn't Malaysia ATC ask why the transponder was off...they would have had to know that flight number, altitude, etc were not on the screen anymore. If they did and the pilots said we turned it off to check the system, then why hasnt that been announced yet either...

This, malaysia had to see that the plane they were talking to was no longer squawking.

I'm sure they tried but got no response.

edit: Im not sure, but I would imagine they tried

So they tried....got no response...but then heard "Good Night?" And they didn't think something was f00ked up. LOL.

Obviously this was a pilot or copilot thing. No other theories make sense at this point, until something more is released. Why don't they play the tape of the ATC communication the last 15 mins or something.

A family member who is a 777 captain shared at least one personal experience that sounds horrifyingly similar to the fire scenario that's being explored.

In this particular case, he was lucky and smart enough to isolate and shut down the panel where smoke was detected before things got out of hand.

But he had to stop his less experienced first officer from taking an action that could very well have downed the plane.



The obvious lack of details in your post makes me question this.

this is what gets me...

these are different types of ATC panels. Note that ATC isn't one guy looking at one screen.







note every one has info from the flights. Such as airspeed and altitude. This info comes from the transponders themselves. When you talk to ATC, they look and see who they are talking to.



In this image you see a GA plane Squawking (note the "n" number instead of a flight number) a commercial plane "the one with a flight number instead of a "n" number and a VFR flight (the 1200).

but when there is no transponder, the plane is just a blip with no info.

Before Malaysian ATC handed them off they should have mentioned "Oh hey, your transponder isn't reading, can you check it" "Squawk xxxx please"
So right here we know that Malaysian ATC screwed up.

I'm still leaning with the stolen plane theory.

The details (as they exist), lack of any floating wreckage, and time sway me. I realize I may be wrong.

Maybe the pilots pulled a Capt. Sully on the ocean and the plane sank intact.

Why though, whats the motive?


Capture Plan = $$$ and Terrorism
Crash the Plan = Suicide

Why go through all of that just to off yourself? Unless you wanted to create the ultimate mystery.
