If you think about it the UFO, in the classic sense, is over. Technically it stands for unidentified flying object which can of course mean any unknown thing flying around the sky but in the past the UFO has been associated with extraterrestrials and science fiction.
2015 is the year of the personal drone and that simultaneously makes it the year UFOs are no longer interesting. I’ll give you an example:
Daughter: “Daddy what is that circular object hovering in the sky! Could it be space people!?”
Dad: “Probably the damn neighbors spying on the neighborhood again.”
These days UFOs are boring because, really, they probably are just your neighbor spying on the neighborhood, or someone running drugs, or Amazon delivering a package.
