drones
drones have been used by early 1970 and surely been around much earlier--just not by humans.
Today drones can be gigantic and super fast, super dangerous.
World - wide drones of all different types have been video taped on the ground and in the air--some that can survive "everything", such as being hit by a semi truck and the drone just keeps on going...
Drones normally are "spies"..earth has been plagued with them before man could make one.
By mid 1970 drones that appeared as a ball of light, always made a "hum" you could hear about 100 yards away. They normally flew in a zig zag pattern about 20 feet above the land---they spied on people and surely all animals.....it is hard to estimate their size, because all you could see is the ball of light. You always heard them first. They would come up and snoop around barns, snoop on working people. Never seen in the daylight.
These drones always came with flying saucers and or large space ships or a fleet of large space ships---the large ships were gigantic, surely nothing humans could make by the mid 1970's. They came with flying saucers, extremely well built, at least 40 feet in diameter and 20+ feet tall with 3 huge stainless steel legs- the crap looking movie flying saucers or the crap looking gov flying saucers of the 1960's--- the 1970's flying saucers looked like they were capable of space travel.
Later on a tell all paper back book came out with the "exact" picture of the 1970's flying saucers, complete with the props and explained in detail----they were alien flying saucers and that soldiers were being trained to fly them--------then kids that grew up on air force bases pre 1980 said: as kids, their dad and them would set out side late at night and watch the flying saucers return to base.
Do not believe anyone that suggest otherwise-- history suggest that by 1950 gov had no choice but to be "controlled" and humans as pawns, more cattle like than you can imagine....
FACT: red clearance army pre 1950 had fully functional earth bases that they could send objects from 1 base to another using magnetic travel and they had a map showing over 200 named planets that people in ancient times traveled to earth from--- those types said space travel is more like "star war" movies than you dare to ponder---- deep space not so friendly to "eatable" species......all "life" planets are floating restaurants...
Today- 4 legged / hoofed animals appear to be the food choice.....good and bad depending how you look at the farming of earth.
