Inmarsat
The simplest explanation is that inmarsat are tracing a terminal not installed on the lost aircraft.
Once ranging errors are allowed for, the likely location of the inmarsat terminal is the maintenance base at KL.
Take the pings out of the equation, and we have a very simple scenario; fire compromises comms system, fire results in loss of aircraft control. Aircraft crashes in Asia.
PS: i've been posting this hypothesis since the 16th, but my posts have never appeared.
