Ever since I first saw a video of a flying humanoid, it has made me wonder about an article on keelynet.com that I had read.
http://www.keelynet.com/greb/greb.htm
It is about Viktor Grebennikov, a Russian entomologist, who discovered the Cavernous Structures Effect (CSE). In his diary, he claims to also have invented a flying platform after accidently coming across antigravity effects in the microstructure at the bottom of the chitin wing case of an insect. What made me put the humanoids and him together was the following statement:
"I am not seen from the ground, and not just because of the distance: even in a very low flight I cast almost no shadow. Yet, as I found out later, people sometimes see something where I am in the sky-either a light sphere, a disk, or something like a slanted cloud with sharp edges that moves, according to them, not exactly the way a cloud would.
One person observed a "flat, non-transparent square, about one hectare in size"-could it have been the optically enlarged little platform of my device?"
So apparently, he was perceived as different things depending on who was observing him from the ground.
He also believed that what people think of as ufo's could be other's on antigravity platforms, and that he was not the first one to have developed them, because of what happened when he crashed once. He described it as digging a well with a side tunnel with no slag and having heard of similar tunnels reported in the news that were not created by him.
So I think the article is an interesting read, if nothing else, and could be an explanation of a lot of things. Flying Mexican humanoids, ufo's, time travel, space distortion, and flying carpets are just a few things that come immediately to mind. And to top it all off, he may have died under mysterious circumstances, judging by the reaction of his son about giving out additional information.
Something to think about.
