They spent a week searching the wrong ocean for the plane. They had the thing on radar showing definitively that it was nowhere near the initial search area. They had satellite data showing it continued flying for hours after the supposed last contact.
I imagine the experts are not to blame here. But whoever is managing them is doing a terrible job of it.
Yeah, this amateur speculation is not useful. But at least it's not actively harmful. How much time and money was wasted searching the Gulf of Thailand before these clowns finally admitted that it was evident the plane wasn't anywhere near there? How much time was lost that could have been used to search places where the plane might actually be?
Decrying amateur speculation on the internet is silly. People are going to waste time regardless. Would you rather they do mental exercises or just look at cat memes? If you want to get upset at somebody related to MH370, there are far better targets.
"MH370 might have entered into a blackhole and come back as a dove.
"What's with all this speculation?!?"
I love the internet tactic of making obvious insults that aren't 100% literal, then turning around and saying "I never said that, prove that I said that." It's hilarious.
