Love the moon landing ones and also TWA 800 .... two of the best.
I recently chanced upon the Titanic Did Not Sink in 1912 conspiracy theory.
Quite fascinating.... Compelling actually. It was the Olympia that went down in a massive insurance fraud scheme. The Titanic sailed thru the 1930’s.
Seemed more reasonable than the iceberg theory... But then, makes little difference one way or the other.
