1. The Roswell Incident (1947)

The Roswell Incident stands as perhaps the most iconic UFO case in history. In July 1947, a mysterious object crashed near Roswell, New Mexico, prompting an official statement that a “flying disc” had been recovered. Within days, authorities changed their explanation to a mere weather balloon, fueling widespread suspicion and conspiracy theories. For decades, many have claimed the government covered up the recovery of alien technology. This event continues to shape public perceptions of UFOs and inspire countless investigations and documentaries.

Debate still lingers over what Arnold actually saw, but his sighting undeniably ignited modern interest in UFO phenomena.
