The fallacy is not obvious to me or others on this thread. Please point it out for all our edification. On any given day, there are many ships of all size inbound, outbound and just passing by Southern California ports. Why didn't any of them report seeing anything?
It is not reasonable to assume that there were any ships that saw it, but there could have been. If there were, the liklihood that they would have reported anything to anyone but their log is about 5%.
