Roswell Incident
A nearly 22-minute video titled “The Roswell Incident” has been quietly uploaded to the National Archives, reigniting interest in an alleged UFO crash in New Mexico in 1947. Investigative journalist Ross Coulthart tells “NewsNation Prime” there is no known archival footage of the incident, and someone is “just having a bit of a fun game.” #UFO #UAP #Roswellincident | NewsNation
