while driving, my friends girlfriend said, hey, look at that! we all looked out the window and into the sky ,where we saw a sphere shaped object with green pulsating lights. the craft seemed to be moving along with our car , probably about one thousand feet up, maybe more. it moved very erratic zig-zaging as well as flying level. it made no apparent sound. we proceeded back to her house where she went inside to call the police. the police dispatcher said, they already have had several people who previously called about the same sighting. as we watched this ufo, sometimes it would implode and show up on the other side of the sky. then return in the same manner. after about twenty more minutes of watching this craft, two military helicopters attempted to fly close to it. when they got close the ufo ,once again, imploded .then appearing on the other side of the sky . it came back once , then the chppers tried another attempt to get close . this time the ufo dissapeared for good. also wanted to mention while all this was happening our car radio would not work. just a bunch of static. really weird stuff, that night!!! if anyone else saw this please report it to this sight so we can compare notes. also if my friend and his girlfriend remember this event , please leave a sighting report. you know who you are. he was from fanwood , like myself, and she was from edison.
