In April 2013, unknown gunmen carried out a highly coordinated sniper attack on the Metcalf Transmission Substation in California, one of the most critical nodes in the United States power grid. They cut fiber-optic lines, fired more than 120 precision rifle rounds, and disappeared before police arrived.

No group claimed responsibility. No suspects were arrested. The FBI ruled it was not terrorism. Yet experts quietly called it a potential dress rehearsal for a larger infrastructure attack.

Was it domestic extremism? A foreign intelligence operation? A disgruntled insider? Or something never meant to escalate beyond a test?

In this episode of Still Unexplained, we explore one of the most chilling unsolved infrastructure attacks in modern American history and examine the theories that continue to haunt national security officials.

Perfect for listeners interested in unsolved crimes, power grid vulnerabilities, domestic terrorism, national security, and modern conspiracy mysteries.

What exactly went wrong on a planet so similar to our own? Was Venus always doomed, or did something trigger a catastrophic runaway greenhouse effect? And could Venus be showing us a possible future for Earth?

The Hanging Gardens of Babylon are remembered as one of the Seven Wonders of the Ancient World, yet no physical evidence of them has ever been found.

In this episode of Still Unexplained, we explore the mystery through a different lens, tracing the legend beyond Babylon and into the powerful Assyrian Empire, where some historians believe the gardens may have actually existed. Were they built by an Assyrian king in Nineveh and later misattributed by Greek writers? Or were the gardens a myth shaped by centuries of retelling?

A story of ancient engineering, Assyrian ambition, and a wonder that may have been misplaced by history itself.

In February 1978, five young men vanished after a college basketball game in Northern California. Their abandoned car was found in the mountains, perfectly operable yet inexplicably left behind.
