UAP Knowledge Center
In the Knowledge Center, UAP Coalition Netherlands brings together background articles on Unidentified Anomalous Phenomena (UAP): what they are, how reports are scientifically assessed, and what they mean for the safety of aviation, defence, and critical infrastructure.
The articles are written for professionals in aviation, the police, and the armed forces, and for anyone who wants to approach the subject factually. New to the subject? Start at What are UAP? and The difference between UFOs and UAP.
