Surprisingly, it sort of worked.
Whether this is telepathy or clairvoyance, I cannot say. If the person broadcasting what they were actually seeing had the telepathic ability and the person receiving it was a strong receiver, that's one thing.
If the person "seeing" wasn't picking up stuff from a given sender, but was actually "seeing" something no one else was sending, that may be clairvoyance.

I don't know.
Remote viewing is difficult.
It also isn't easy to refine. You might be seeing someplace, some route of travel, that isn't the one people want you to see. You could be one street over. You could be tuning in to something more powerful than the specific thing you were aiming for. There is nothing an individual can do to control this. As with all psychic, sensitive gifts, it just happens.
And it's so unbelievable, nobody really pays attention.

So here I come to the story of Cassandra of Troy. She was a priestess or something like that back when people believed there were individuals who had a direct line to the gods and got all sorts of information from the guts of dead animals. She pissed off one of the gods and was punished by being able to see things happening...but the spiteful god also made her suffer by not having anyone believe what she saw.

"I see the Greeks defeating Troy from inside the mighty walls. All will perish." Something like that is hard to take, but back then, people would have sort of paid attention to a priestess known for prophecy and clairvoyance. Did they? Hell no, she was cursed. Nobody believed her, the nasty, wily Greeks got warriors into the walls in the body of a giant wooden horse and the rest is history.

This still goes on today. The search for a way around the ordinary, a way of using talented psychic people to get information and getting pissed off when it isn't precise, isn't exact, can't be turned on or off at will. And then there is Madame Trelawny in the Harry Potter books. She has visions of what is going on and she's so far out, so strange, no one believes her. No one wants to believe her.
But every thing she says while in her clairvoyant trance is true.

In the book.
Yes, that's pure fiction.

But these people do exist. These people able to see far away. Perhaps.
Perhaps they're just crazy.
Perhaps they don't get the details in their flashes of remote views correct and are total write-offs as far as science is concerned.

They do make excellent characters in a book, however. Excellent.
Clairvoyance-the ability to "see" remote events.
Also clairaudience, the ability to "hear" something going on far away, clairsentience, the ability to feel or "sense" things going on at a distance. (works well with mother and child, lovers)
