You might have thought a defining characteristic of a UFO would be visibility. But thanks to zealous alien hunters doggedly scanning the sky with night-vision cameras, a new class of flying objects that only emit infrared light has emerged from the darkness. Are they spies from the great beyond? Some people claim to see actual battles between UFOs up in the sky, using night-vision equipment. Ed Grimsley has been seeing battles between unknown aircraft in the night skies since he was a teenager. Since then he has continued seeing what appear to be Delta shaped and Saucer shaped aircraft in space shooting it out using what appear to be laser weapons. He has seen hundreds of these objects recently and using his five Military grade night vision binoculars he has invited many people to come to his areas and view the objects in earth space shooting it out. Using his night vision glasses, even skeptics who thought he was 'seeing things' have now been convinced that what Ed Grimsley has been trying to tell people about all these years is very real.
