blue belly: ship with blue light outlineing the bottom of saucer, white ball of light on each end. top: one white ball of light on top

blue belly:i have seen a ship, it had a blue curved line;a lighted line (the color of blue chalk on a chalk board) on the bottom of what appeared to be a disk shaped vehicle. on the front and back end, it had a small ball of white light, and on the top was a slightly bigger ball of white light. there was no noise at all.                     one night around 1978-1980, i was sitting on my porch with my 2 yr old nephew, and my small terrier dog was on my lap. i was around 12yrs old.    my dog became incredibly nervous, so i put her in the house. (my memory of the date is terrible, but remembering the incident is extremely vivid) approximately 5 min. later, after the dog was put in, i saw the "blue belly" enter the sky to my left, it seemed as if it had slowed down for a minute. it moved around 8-10 miles (from Tracy to French Camp) at a speed of (estimate:10,000 mph) for almost 1-2 seconds, then took off(probably way over 15,000 mph)towards tahoe for a visable 1 second.then it seemed to cut into the sky and disapeared. it left a bluish vapor trail.(i must say, the haunting image i can never forget was:like seeing god; it was so beautiful, sacred,and graceful; and there's nothing like seeing advanced technology in action:it's awsome!
Date and time are approximate.  We have arbitrarily assigned a date in 1979 so that the case sorts to that date.  PD
