If it was an oxygen fire in the cockpit the pilot on whose side it occurred would not be able to use his oxygen mask, even as a smoke protector. He would be subject to smoke inhalation, and perhaps depressurization, depending on whether or not the pressure vessel was breached.

In thinking further one of the first things the crew would do in case of a fire in the cockpit would be to depressurize, so it wouldn't matter if the cockpit fire burned through the skin or not as far as pressurization is concerned.

The problem so far with *any* theory is that they all match some facts, and are totally contradicted by other facts.

I suspect one of two things will eventually happen:

Bingo. It is going to be amazing when they find it and figure this out.

Got to add this to the "black hole" and "alien abduction" theories.

I'm assuming like most aircraft, the 777 also has a PBE in the cockpit.

Well, that is a good question. Does the 777 have PBE (portable breathing equipment) in the cockpit to augment the crew supplemental oxygen. The regulation I found indicated the pilots oxygen system would satisfy the requirement for the PBEs, meaning there would not be a requirement to carry both in the cockpit.

Yes. I've never flown any airliner that doesn't have a PBE or two stored in cockpit. However a PBE is only going to buy you about 15 minutes tops.

The only reason that there is a PBE in the cockpit is because one is required to be near every fire extinguisher

Thanks, looks like the rule is FAR 121.337 (b) (9) (ii) which requires one PBE on the flight deck. The one per fire extinguisher rule is for the passenger compartment.

Please can you be more specific which facts this does not match in your opinion, rather than offering a blanket dismissal?

The final manouvere sent by transponder just after passing waypoint IGARI was a turn west to 040 degrees:

The last location tracked by Flightradar24 was
Time UTC: 17:21:03
Lat: 6.97
Lon: 103.63
Alt: 35000
Speed: 471 knots
Heading: 40

If an electrical problem developed then that would explain a turnback southwards

If the electrical problem led to a fire in cockpit O2 lines then that would explain sudden incapacitation.

Please be more specific which facts this theory does not match?

INMARSAT Doppler tracking confirms now that the aircraft flew a steady course at a steady altitude over 30,000ft
