And now that I think of it, go back and read what I said about hovering again.
I never claimed that things cannot do so. Only that when they do, it is by some method that can be detected, like wings moving like crazy, jets or rockets or rotary wings pointed downward, strings from above (as in some of the hoax photos), etc. It is folks like you that claim that a) they are up there at all, and b) they are staying up there using some kind of miraculous science.
