This is Brian Dunning's new article, received today in the Skeptoid Companion. It's about his upcoming independent movie on the topic, and is a good discussion of the practical aspects of UFOs as well as skepticism in general.

They are observations grounded in physics equations, and math is math, everywhere in the universe. We look at how we've been able to verify that the laws of physics today are the same as they were billions of years ago, and how we've been able to verify that the laws of physics here are the same as they are on the other side of the universe. Math is math. The aliens' math will give them the same answers that our math does. If you try to brush that aside with the illogical "The laws of physics don't apply to aliens," then you've abandoned our shared goal of better informing our beliefs with science. Instead, you're informing your beliefs with the magic of leprechauns and genies.
