What happened?

A heavy metal sphere found by the Betz family in Florida in 1974 became a long-running UFO-adjacent mystery after reported odd movements, Navy inspection, X-ray claims, and later industrial-object explanations.

Why it still matters

Source set meets the current publication gate; interpretation remains provisional pending stronger primary-source review.

Current read

The sphere and its media history are well documented, but extraordinary behavior and origin claims rely on fragmented secondary accounts and face a plausible industrial-object explanation.

Why the signal is high

This case has multiple accessible sources, a durable visual record, recurring anniversary coverage, and a clear unresolved residue: the later light row is explainable, while the earlier formation accounts are harder to reconstruct cleanly.
