Driving on a country road. Very noisy craft above tree tops. We reached top of hill where sky could be see. 
Then noticed a circular object which now had travelled about 2 miles North.  At this point the object which had orange lights was now going straigt up in the sky into nothingness.  
It was observed by 2 adults and 5 children between the ages of 4 and 13.
