After communications were lost, the only certainty I've seen is the radar data from just off Butterworth heading WNW at FL295 until it reaches waypoint MEKAR - the time over MEKAR is depicted as being 2.22 Malaysia time.
Where did FL295 come from?
I've only seen one image of the radar information and that showed not a waypoint at O2.22 but a
RADIAL295 200nms from Butterworth[
