It's beyond doubt that people see strange things in the sky. It's also quite likely that there is no single explanation for these oddities. So-called "unidentified aerial phenomena," as the government now calls UFOs, are likely a combination of natural and human-made objects along with a strong dash of people misinterpreting what they see under the influence of more than a century of alien-themed science fiction. Investigating individual military sightings should be encouraged; uncovering whether some of these perhaps represent adversaries' efforts to spy on America should be an obvious counterintelligence step. That doesn't justify leaping to conclusions about superhuman technology or alien invasion, particularly when reasonable explanations have been proposed for nearly all the allegedly incredible sightings.
