First off, this is a UFO cloaked in a cloud. How do I know that? Several reasons. First the 1957 case where a US Army soldier photographed a UFO slowly cloaking itself within a cloud. (Click here to view). 2nd, when I was in the USAF at a SAC base, my UFO sighting (seen by thousands) saw four long tunnel clouds created by 727 size glowing balls of florescent light. These tunnels were used every 20-30 seconds for another ball (over 25 UFOs in total) to start traveling down...like cars in a tunnel. Hidden from human view. Except they started above my parking lot in Rapid City, SD. 15miles from my base. Believe me when I swear that this is a UFO forming clouds around it to hide. SCW
News states:
An interesting sight was captured on camera in Southern Utah on Sunday -- a cloud in the sky that resembled a UFO.
Colleen Chandler Rue snapped the photograph in St. George, which shows a Lenticular cloud in the sky. Lenticular clouds are stationary lens-shaped clouds that form in the troposphere. (More at source).
