Malaysian Prime Minister: Missing plane crashed in Indian Ocean

No one has found anything in person yet except some wood with straps on it that cargo is sometimes secured to, but ships use these also and they're not sure it's from the aircraft yet. Lots of debris has been sighted in many different areas via satellite but when they arrive in the area nothing gets found.

So far it seems this is entirely based upon analysis of the SATCOM ping data. Unless they have information they aren't yet sharing, I feel it's somewhat irresponsible for the Malaysian government to tell family conclusively that it crashed into the ocean with no survivors when they haven't even found wreckage yet.
