Yet just a few years ago, the Pentagon reportedly shut down another official program that investigated UFO sightings. What has changed? Is the U.S. military finally coming around to the idea that alien spacecraft are visiting our planet?
The answer to that question is almost certainly no. Humans' misinterpretation of observations of natural phenomena are as old as time and include examples such as manatees being seen as mermaids and driftwood in a Scottish loch being interpreted as a monster. A more recent and relevant example is the strange luminescent structure in the sky caused by a SpaceX rocket launch. In these types of cases, incorrect interpretations occur because people have incomplete information or misunderstand what they're seeing.
Based on my prior experience as a science advisor to the Air Force, I believe that the Pentagon wants to avoid this type of confusion, so it needs to better understand flying objects that it can't now identify. During a military mission, whether in peace or in war, if a pilot or soldier can't identify an object, they have a serious problem: How should they react, without knowing if it is neutral, friendly or threatening? Fortunately, the military can use advanced technologies to try to identify strange things in the sky.
