My wife and I were driving back from the grocery store on our way home, when I pointed out a helicopter, then saw an unusual blu-ish dot speeding up and going faster than the helicopter, then my wife said "is just another plane or helicopter" I went ahead and pointed out that there was no blue and red lights on them. The object went very fast north, I speed up to catch up and the object just went faster half way stopped in mid-air we thought that we were able to catch up to it then it went an an incredible speed making a zig-zag shape from north to west to north west in 90 degree turns. As the object was speeding up and turning the object turned into 2 exact copies, swirled for about 5 times before merging together and disapeering going straight up in the sky at that point we lost visual contact. I was excited since is been long time since the last time I had seen one, however my wife was in a panic mode not being able to understand what she just witness, I had to help her get her mind of the event and help her go sleep.
