shiny disk shaped with a raised dome on top in the middle,rotateing light[white] moved around bottom.

metallic disk,round port holes in center top, appeared to have a rotating light omitted from inside the craft. It appeared in a very populated area[in town], it seemed to make no noise and approached the back side of my parents property stopping at tree top level. I ran inside the house and phoned Richard Gabaur airforce base and made report, then called the Raytown Mo. police dept.  After I went back to the back yard it moved almost unbeliveably quick, straight up and then disappeared almost instantly. I also got on the C-B radio and spoke with many, many people in the immediate area that wittnessed the same thing.
Date is approximate.  PD
