Hey guys, I would like to explain my theory to you, which, at least in certain points, coincides alarmingly with events/explanations of Preston Nichols book about the Montauk project:

1. A person disappears in the national park. Why there? For one thing, because it's on US territory. On the other hand, because as a relatively isolated place it generates less unwanted attention than it would happen in the middle of a city.
2. Fog suddenly appears: Possibly the technique of the Phoenix Project is used here. Adverse circumstances are deliberately created that completely contradict the weather forecasts. This means that searches can be delayed as long as required until the crime scene has been cleared or the person is allowed to be found.
3. Intellectuals are disappearing for the most part: Similar to Preston Nichols, these individuals are being 'remodeled' on an alternate timeline to do their work within the framework of these secret projects. Maybe they are cloned so that they exist on 2 timelines?
4. I can't put into context why children disappear. But why they say that they were protected by bears could be a deliberate manipulation of the memories to obscure the actual events or memories.
5. Why do people generally not remember anything? Here, too, parallels to Preston Nichols would be possible. The memories may be deliberately deleted to protect this secret project. Since the methods may have been significantly refined, no memory return is possible with hypnosis
6. People run their feet sore to the bone: In the book about the Montauk project, John von Neumann talks about how a failed 'teleportation' can drive people insane. Since the affected person feels their apparently familiar surroundings as not so familiar (simulation of the familiar through electromagnetic waves), they run - driven by madness - until their feet are sore to the bone.
7. People, including small children, reappear miles away, sometimes behind several mountains from their originally planned route or last known location. In some cases, as mentioned in the books by Paulides, they could not have covered the distance in such a short time. Especially when the cases were about toddlers going missing. Here I think back to the Philadelphia project, through which objects and people could be teleported to distant places.
8. The people, especially the one ranger who disappeared below the Half Dome, said that while they recognized some of their surroundings, it was completely different and strange. The simulation of the seemingly familiar environment that von Neumann theorizes may have failed in that moment.
9. People report a humming noise, possibly before these mysterious Missing 411 phenomena are about to occur: I'm not a physicist and I don't know if waves of any kind can make a sound, but maybe this is the 'starting noise' for the machinery, that causes these phenomena, or it’s the waves themselves.
10. People reappear days later at places already searched: Perhaps the missing people are in that other dimension in the meantime, and are (deliberately or not) 'brought back' to specific places. But it is unclear to me for what purpose, since that only brings unnecessary attention

11. The FBI investigates missing persons cases that sometimes seem harmless and is quickly on the spot: Either the FBI is in the know and is investigating the results of this 'kidnapping' or teleportation. Or the FBI knows about these strange phenomena, but is left in the dark by the highest authority about the background.

    But the question remains unanswered as to why some of the people are found again naked and with folded laundry. That doesn't fit into any context for me.

    I'm not claiming to have found the holy grail, but whether or not you believe the depictions in the Montauk Project book, isn't it odd that these things are somehow intertwined by coincidence? Of course, these are very adventurous theories, but the core theses would explain the whole thing relatively well.
