Beware of CSETI and other disclosure programs as they do charge money to join. Seminars can cost $1000 or more depending on what one asks for. The person is also required to sign a nondisclosure agreement of what they will be viewing. Sounds a bit ironic, doesn't it? Joining a group whose sole purpose is for the government to disclose what it knows only to have its members sign such statements.
Disclosure is not going to happen anytime soon.
There is always the possibility that the government and military are telling the truth when they say they do not have anything to disclose. Do I believe that personally? No.
