Fifty meters down, the light in Lake Baikal turns the color of old glass. It is cold enough to kill an unprotected swimmer in minutes. And yet, according to one of the most retold stories in Soviet UFO lore, that is exactly where a team of military divers met something swimming beside them that had no business being alive.
The figures were human in shape but enormous, close to three meters, or nearly ten feet, tall. They wore tight, silvery suits. Their heads were sealed inside round, transparent helmets. They carried no tanks, no hoses, nothing at all to breathe with. They moved fast, and they seemed to be watching.
The divers surfaced and reported what they had seen. Their commanders, the story goes, made a decision that would cost three men their lives: catch one.
A squad of seven divers went back down with a net. As they closed in, some unseen force hurled the whole team toward the surface. A rapid ascent from that depth is one of the deadliest things that can happen to a diver. Nitrogen bubbles out of the blood like soda from a shaken bottle. The men were stricken with decompression sickness, the bends. There was one working pressure chamber nearby, built for two. Four men were forced inside. Three of the divers, including their commanding officer, died. The survivors were left disabled and, we are told, never spoke of it again.
It is a perfect story. It has a remote, secretive setting, a military cover-up, real physics, and real bodies. It has been repeated on hundreds of websites and in television documentaries, often with the claim that it comes from declassified Soviet files.
But when a Siberian researcher finally tracked down the man who made the story famous and asked him a simple question, where did you hear it, the answer changed everything.
