Saw a white light streaming accross the sky, turned yellow, expaded to a bright blue orb and remained still emulating a perfect expanding ring of fog. The blue light faded away after 20 minutes. I hoped on google and found many vidios of the exact event around the word! Kusi also reported event with footage. Kusi claims milatary was testing....some of the footage that i found has already been removed off the net!! Viewed in my back yard with neighbors. was very concern with the fog released because it grew to a massive size.
