Here is an older sighting that I had never seen before, so I will post it here. A UFO cloud was seen back in March of 2017 over Scotland and as it passed over a hill...a colorful thick rainbow appeared linking the ground to the UFO. I believe that the UFO was of course beaming people and supplies down to an underground base about 4-6km below the ground. An incredible once in a lifetime sighting. In my 15 years of reporting UFOs, I have never seen a UFO that created a rainbow. I have seen them in the rainbow or near it, but this is a first.
