For all of the wild speculation surrounding the fate of Malaysia Airlines Flight 370, one pilotís theory about the missing airliner has gone viral for a different reason: it - at least on its face - seems to make a lot of sense.
Aviation blogger Chris Goodfellow has flown commercial aircraft for 20 years, and posted the take on his Google+ page.
In short, Goodfellow theorized the plane experienced an emergency fire, prompting the pilots to turn around and attempt an emergency landing at a nearby airport in Palau Langkawi, a small island off the western coast of Malaysia.
This pilot did all the right things. He was confronted by some major event onboard that made him make that immediate turn back to the closest safe airport.
For me the loss of transponders and communications makes perfect sense if a fire. There was most likely a fire or electrical fire. In the case of fire the first response if to pull all the main busses and restore circuits one by one until you have isolated the bad one.
Goodfellow theorizes the smoke may have incapacitated the crew and passengers before they were able to reach an available airstrip.

Amateur sleuths on the Reddit's MH370 discussion boards have started a thread to analyze Goodfellow's theory.
