I think he pretty much shot down aliens visiting earth in physical form in this video. He really starts talking about it about 50 minutes in.http://www.youtube.com/watch?v=Ir7s74-C ... ploademail
Tom: I remain, as always, open minded AND skeptical. If you were as old as I am you would know that the aliens have been collaborating with our government and on the verge (certainly this year) of being made public every year for at least 60 years. This story has been a constant humma humma of fast breaking news in the margins for almost a century. In that time, worldwide, hundreds of government leaders antagonistic to each other have come and gone. Indeed, where are those exceedingly shy aliens?
