UFO secrets are reportedly being revealed this weekend at the National Atomic Testing Museum in Las Vegas. Will those secrets have any real impact on how the media and public look at UFOs? Four retired Army and Air Force colonels and a former British Ministry of Defense investigator join forces this weekend at the National Atomic Testing Museum to speak on a subject public officials rarely address -- UFOs. The Smithsonian-affiliated museum's special lecture, " Military UFOs: Secrets Revealed " is open to the public and has been long anticipated by researchers of unexplained phenomena. The exact nature of the secrets hasn't been revealed, but the participants form a historic who's who of UFO researchers spanning half a century. At least one of the participants has strongly hinted he's going to reveal startling UFO-related information that hasn't yet seen the light of day. "I'm going to explain what I think and what I believe, and this is after all these years thinking about it. I think I've got the answer and no one has ever mentioned it," said retired Air Force Col. William Coleman.
