Argh!!!! The Malaysians now say last radar echo was from west of the Peninsular Malaysia?????? Why didn't they say this earlier???.
Because it hadn't been confirmed?
I really don't see any big conspiracy over this change of SAR mission from the east of to the west of the peninsula. When the flight first 'went missing', it was positioned east of the peninsula heading NNE so naturally the search was concentrated there.
In the meantime the military has said privately to the government 'hold on we are pretty sure we saw something heading west without identification but need too look at our raw primary data to get a better picture' (and check that nothing classified was being revealed!) On the strength of this some assets were diverted west to the Straits with the caveat "We can't say why" presumably because all the information wasn't in yet, and now the military have come back with confirmation that they did track an unidentified aircraft heading west towards the Straits and today that information was made official.
What's the big deal?
