Round and angular “C” or “V” shaped crafts are infrequently reported. They are usually accompanied by loud, booming sounds that shake the ground and surrounding buildings like a minor, brief earthquake. Those that see them note their very large shape in addition to the craft being white or silver, dotted with several flashing lights on the bottom or side of the object, and moving at a very slow pace before vanishing into thin air. Some of these UFOs are also seen alongside storm fronts or lightning, specifically coinciding with the occurrence of blue lightning at night. Most often, they appear in the sky as dark, shadowy silhouettes with bright lights on the corners or edges. 

Some believe that these spaceships are resource gathering crafts or ones passing through, traveling elsewhere.
