There has been a lot of speculation recently that some of the spy balloons, or whatever they are, may be from another solar system rather than another country.
This follows the flurry of stories over the last few years about all the sightings by commercial and military pilots of various unidentified flying objects. There are serious claims that these UFOs often behave in ways that no man-made vehicle can match. In some reports, they seem to violate the rules of physics as we understand them.
I may be uniquely qualified to discuss alien possibilities, since I was shown in the original “Men in Black” movie as an alien — along with Sylvester Stallone, Danny DeVito, and a number of other disguised aliens living on Earth.
