Hello, great article. I fully agree that military personnel, police officers or pilots are great sources for UFO stories, because I don't think they would lie and risk their careers for some non truth story. I am pretty sure that there is life on other planets, because space if to vast with to many galaxies and planets and it's impossible that we are all alone in it. Other question is what level of intelligence those life forms have, but I also don't think we are the smartest in universe. My opinion is that there are far more advance civilizations in Universe than we are, but contact with them could be risky for us, because who knows what they can do to us.
