I knew about this case, although I did not knew so many details as those posted (although it's a shame we don't have more specific details about what really crashed), and this is another of those really unknown cases that I think are the best proof that something has been happening.
What that "something" is is a different story, I don't think that we need to "borrow" someone from another planet to explain this type of event; only when we have proof that it could not be something made on Earth then I will consider an extraterrestrial explanation before a terrestrial one, and although this is a great case, I don't see anything that makes it impossible for whatever crashed to be from Earth.
But a possible Earthly explanation is just that, a possibility, and even if I think it more likely than an extraterrestrial explanation I do not see any reason to exclude that possibility from the list.
PS: I think ATS should find a way of making threads like this more "visible", they have so much information and they are presented in such a way that I think they as good as any mainstream publication.
