If such a thing as "UFO's" exist, they would certainly have the ability to do as they wish. Any restraint that they might exercise would no doubt be their effort to minimize panic among the "simplistic" life forms on this planet. IF they exist, that is. Answer: I believe UFO's could appear anywhere and anytime. I think most sightings of UFO's occur at night. I think space aliens prefer to visit Earth at night because fewer humans will see them. Maybe the aliens are concerned for the humans safety, because crop circles, allegedly made by UFO's, flatten crops, and some dead farm animals (although often unusually mutilated suggesting actual possible physical contact with aliens), have been found laying in farmer's fields, suggesting they may have been killed by radiation, heat, light, fear, or whatever, resulting from a UFO coming close to them. Maybe the aliens fear if they get too close to humans, that humans could die or get sick from the UFO's radiation or whatever. Maybe UFO's prefer to visit Earth at night because they're on surveillance missions and don't want to attract attention.
Most sightings are the result of luck, the right place at the right time. There is no pattern or any way to predict when UFOs appear.
UFOs have been reported in virtually all of the states at one time or another.
Yes, there are.
None recorded.
Yes. Any time you look up into the sky and say "What's that?", you have seen an UNIDENTIFIED Flying Object.
UFOs aren't for sale. Any UFO's that may have been recovered would be in the possession of top military personel.
There is no particular significance in birthmarks - of any shape, and anywhere they appear.
UFOs are by their nature, impossible to prove. If they were proven, they would be identified and would cease to be UFOs.
Whatever you imagine it to be. UFOs by definition are not known to be any form of aircraft or animal, and so are not known to have any wings whatsoever. Most definitely they are not known and proven to have anything to do with aliens, since there are no known aliens anywhere in the universe.
There doesn't appear to be any company by that name anywhere in the UK.
No accurate records exist.
Two offical sightings reported.
