Betz Mystery Sphere

Following a brush fire, the Betz family discovered a polished metal sphere about 8 inches in diameter on their Florida property. The sphere reportedly exhibited unusual behaviour, vibrating, emitting sounds, moving on its own and responding to musical tones. Examined by the US Navy and physicist Dr. Carl Willson, no conclusive explanation emerged. The sphere remains one of the strangest publicly documented recovered objects of the modern UFO era.
