Is it because they are Governments tests gone wrong? Is it because ET isnt used to our Gravity? Is it because ET has no decent pilots? Or is it that they are just using Earth as a dumping ground to get rid of their old and unwanted craft? They have never hit a major city, almost as if they are avoiding doing any damage as they are landing in the desert/remote place. Or that the desert is a remote place where the Government can test them.
I just want to know your ideas on UFO crashes.
