UFO Pendulum Motion.

[Karl12]

That doesn't sound like anything being controlled to me, more programmed to move from point A to B. 

Hadn't considered that mate and your post did put me in mind of the 'postbiological' hypothesis where these objects are the result of some kind of advanced machine intelligence - you also mentioned 'underground' and I would wager a lot is going on down there with regards to this subject.

The greys are just some kind of construct that is projected out. Spooky stuff.

Definitely is a bit spooky and reckon the average Joe would be a bit shocked to see just how many UFO occupant reports are out there - just been watching this vid about airports and came across a load more lol.

Farms also seem to get attention from these objects and there's a pretty remarkable UFO occupant/pendulum motion case below from Medellin, Spain on June 14th, 1974:

Santiago Pulido Romero, 46, was going to his father's farm when he saw an object flying at low level. It was "round on the bottom and with a sort of cone-shaped tower on top." When he switched his car lights on, the object came towards him at very high speed, only to move away from he turned out the lights. Inside the craft, Santiago could see three tall men, "who seemed to be holding on to some sort of control levers" and wearing helmets.

" 'How did the apparatus move?' I asked him.

" 'At very high speed and spinning in the same spot, although at times, it zigzagged or remained still, or swayed like a pendulum of a clock. For a moment it would look like a star, and then, in the next moment, it was right there beside me. At times it seemed to me to move like a whirlwind, you know what I mean? — like an incredible maelstrom...Well, it's just that I haven't the ability to explain it; words fail me!'

"What shape was it?'

" 'Round on the bottom and with a sort of cone-shaped tower on top. The round part was transparent and a great yellow light came from inside it. The tower shone and looked like a metal structure.'
