I'm puzzled. It's now approx 18:30 local KL time and sun sets in 1 hour. Local weather seems favourable for searching, the search area seems to be fairly well defined and there appears to be good radar coverage in the area to have it pinpointed. Still, no credible reports of traces after almost one full day's search - no oil slick, debris etc. reported so far.
OK, the sea crossing is some 200-250 NM so it is a sizeable piece of water and the middle parts may be beyond helicopter range. But it's not in the middle of the ocean either.
Hope we get clarity soon.
