"It's been 12 hours in constant day light on a busy route both shipping and air, I immediately refute an explosion theory based solely on those facts, until proven otherwise.
The fact wreckage is not found yet, is immensely troubling after this much time."
I don't think anyone would try something similar as authorities there are much more aware now than before.
But I agree it's strange nothing has been found yet in a very shallow sea full of traffic.
