UFO Sighting in N. BILLERICA, Massachusetts on June 15th 2008 – ASCENDED SLOWLY, ACCELERATED HORIZONTALLY OUT OF SIGHT. SECOND ORB CAME FROM BEHIND ME AND FOLLOWED SAME PATH AS THE FIRST

I WAS SITTING IN MY BACKYARD AND NOTICED WHAT I THOUGHT WAS A BLACK BALLOON SLOWLY RISING, IT STOPPED JUST ABOVE TREE LINE, HOVERED FOR ABOUT 10 SEC. THEN ACCELERATED RAPIDLY OUT OF SIGHT HORIZONTALLY. I WAS HAVING DOUBTS ABOUT WHAT I JUST SAW WHEN A SECOND ORB CAME OVER MY HEAD @ ABOUT 40 FT. AND FOLLOWED THE FIRST ORB
