Large bright blue light in the sky

A friend and I were playing in an open field at the base of Mount Southington.  It was summer and just about dusk when we noticed a bright blue light in the sky, just hovering above us.  There was no sound and it didn't appear to be moving.  We just stood there looking at it wondering what it was and then all of a sudden it just disappeared.  I was so scared that I just ran home and left my friend standing there in the field alone.  When I got home my mother told me that the lights had gone out for an instant and there was no reception on the T.V.  To this day my friend reminds me of how I left her standing alone in the field.  There were reports that it had landed on the mountain and the government had roped off the area.  There were all kinds of military trucks coming in and out of that area.
