Fire?
Anyone posting a theory that fire was responsible for what happened to MH370 must also explain how the airplane continued flying for seven hours. When you can do that, I'll believe fire was the cause.
It's the nature of a flash fire and the characteristics of today's push-button environment. Push that button and things will change. Melt that button and things just won't. It's merely the difference between the "status quo" and "que sera". A flash-fire just sweeps through and fizzles ( if you were a fireman you'd appreciate this distinction).
Just google flash-over or flashover. A flashover, when you unwisely open a door in a burning building, will kill you but it will only scorch the environment.....before subsiding as the combustive differentials in oxygenation are equalized. It's nothing like a fuel-fed fire. That's the nature of an oxygen fire in an enclosed area. While oxygen is feeding, the fire thrives and burning is less apparent than melting (particularly of most plastics). Done any oxy-welding?
Once the oxygen feed is compromised by the low-pressure oxygen hose being destroyed, that low-pressure flow's feed is no longer there past the oxy regulator's internals and so the fire subsides and it is quickly blown out by the slipstream (cockpit sidewall burn-through).
It's as if someone did a single pass through the flight-deck with a flame-thrower. It's a whoosh, lotsa melting and a charred interior. The proximity of the oxy-fed flamethrower to the cockpit sidewall is sufficient to quickly achieve burnthrough. That's why you get that blue flame at the tip of a blow-torch.
Once the fire's out, the systems' status are mostly as was (apart from whatever the pilots initiated in their early event response) .... but later actual actuation of a melted plastic button? Not gonna work again. You're stuck with its original selection.
Got the idea? Novel to you perhaps, but not anyways mysterious to crash investigators.
Try googling NASA the Apollo 1 oxygen fire. It tells a similar story.
P.S. I gave up sucking 100% oxygen after a hard night - once I realized the potential for beard-singeing after eating a greasy hamburger.
