Roswell may be the most famous UFO crash story in the world, but it is far from the only one.

In this episode, Bill and Deb examine three lesser-known UFO crash incidents from around the globe. A mysterious impact in the Soviet Union reportedly left behind unusual metallic material. An alleged crash in the English countryside triggered a large search effort that found nothing. A dramatic event in Bolivia generated reports of sonic booms, military activity, and later claims that something may have been recovered from the crash site.

Some of these stories are well documented. Others become harder to verify the deeper you dig. What they all share are witnesses who walked away convinced they had seen something unusual.
