That the memo exists is not an issue. Obviously, it does, and the news articles quoted it accurately. If the whole thing was a fabrication, or was misquoted, the DOD release (which was oddly worded at best) would have said so. Instead, it simply said that the content of the memo, a list of many different reports (not the reports themselves) should not be interpreted as solid confirmation of the contacts.

I do wonder what all the reports say, and what conclusions COULD be drawn from them. That seems to be an awful lot of different reports on something which supposedly never occurred.
