What happened
On the evening of January 29, 1986, at about 8 p.m., residents of Dalnegorsk in Primorsky Krai saw a reddish sphere fly over the town parallel to the ground and then strike one of the summits of Izvestkovaya Hill, known as Height 611. Witnesses spoke of a flash and flames. At the site, a scorched piece of rock was discovered, along with small droplets of metal and fragments resembling glass, mesh, and fused beads. The investigation was taken up by Valery Dvuzhilny, chairman of the Far Eastern commission on anomalous phenomena, and samples were sent to several scientific institutes in the USSR. In 1988 the Soviet newspaper “Sotsialisticheskaya Industriya” wrote about the case, and the hill became a destination for expeditions of researchers and tourists.
Witnesses
Residents of Dalnegorsk; the samples were collected and studied by Valery Dvuzhilny and the scientists working with him.
Explanations and hypotheses
The conflicting results of the analyses – reports mentioned unusual alloys and fibers, among other things – were never published in peer-reviewed scientific journals. Skeptics point to the fall of a meteoroid, rocket debris, or an electrical phenomenon such as ball lightning. For ufologists it is the “Soviet Roswell,” but the lack of unambiguous documentation means the case remains unresolved.
Unexplained There is no convincing explanation.
