It seems to me that those who are arguing that Bildt's early claims about the cause of the sinking were reliable are missing the point.
Whether Bildt knew what he was talking about in the days following the accident is irrelevant really. Maybe he was talking out his ass. The fact is, what he said isn't particularly relevant because Bildt's early claims aren't a reason to believe the cause was the failure of the bow visor in a storm. The subsequent, well-informed report by JAIC provides all the evidence needed, especially when coupled with the numerous counterarguments to Vixen's theories du jour.
I mean, I don't know about you, but when I first saw this thread, I believed I knew the cause just because I knew of the expert conclusions from the investigation. I've learned a little more about the evidence while reading this thread. I also learned what Bildt said, but I don't reckon that what he said matters much. He might have been well-informed or maybe not. Whatever. It's the bulk of the evidence and reasoning in the report that matters.
Indeed, if a new investigation were to revise the conclusion, I would not be all that puzzled about why a new conclusion would be inconsistent with Bildt's early claims. Initial impressions about what caused the accident have little weight, whether well-informed (considering the information available at the time) or not.
Now, JayUtah has it right. He's pointed out that Bildt doesn't matter. Others have presented explanations of why Bildt would be better informed or less biased than Estine. These arguments are a distraction.
