This is the first time I ever reported this and curious if anything like it has been reported. Some years ago, standing in my backyard, I looked up an saw a triangular shaped object with a round cigar shaped bottom. The craft was a beautiful brillant blue. From the nose what appeared as an electrical charge started and snaked across the body of the craft. As it did the color from the nose bac changed to a beautiful green. When the charge stopped at the tail the entire object was green. Sparks or shrouds of light came from the back (approx. 30 ft long) The object lurched forward and disappeared in a few milliseconds. Anything like this reported before.

One object triangular in shape.   Size approximately 100 feet long.  Bottom of craft appeared rounded.   Color at time of sighting:  Light that was blue.  Noticable change:  An electrical color snaked or wormed through the body starting from what appeared to be the nose.  As the light snaked through the color behind it changed to a beautiful green.  At termination of electrical charge the entire color was green.  Sparks or energy rods shot from the back of the object as it lurched slightly forward and then disappeared in a few miliseconds. I do not wish to have my name released and request confidentiality.  I am curious is anything like this has ever been reported. If you want to contact me by e-mail, please do.  No phone calls or investigators.  Thank you.
Sighting was approximately 1962.
