Terry, I'm not afraid to admit because I don't know anything about UFOs. To be afraid to admit, you first need to know something to hide. I don't have that knowledge yet. Secondly, the governments around the world can behave the same way simply because they might be as dumbfounded about this UFOs business as the rest of us. In plain English, perhaps they also really and honestly don't know much about UFOs. Have you considered that as well? Silence comes not only from conspiracy but from ignorance as well. My conclusion: people observe things but we don't know what they are. Respectfully.
