My children and I were in the hot tub in our back yard which is right at the base of a mountain when my son noticed a bright glowing ball of light in the sky fling south under a trail of smoke from an airplane that was just passing over the monutain traveling west. The object made no noise and traveled at not a very high rate of speed there were no blicking lights and no smoke from the object. We got a little scared so we called for my boyfriend to come see when he got out side it was still in the sky traveling south, he aslo watched the object for a few minutes then he went inside to get the camera and before he even got back outside it just disappered. The object would be very hard to describe because it was so bright just like a glowing ball it's movment was so smooth and moved in a straight line but then just vanished it was there and then just gone. It was a very uneasy feeling it scared my daughter and left me feeling worried I have never had anything like that happen to me before and could have lived with out it.
