there were many people assembled at Holman stadium in Nashua waiting for the firworks display. I looked up to the sky just as it was getting dark and saw a disk shaped object displaying multicolored lights in a circle on underside hovering over at what seemed to be 100 feet above us and the gathering crowd. It stayed for 30 seconds and then shot off at an angle toward space in an instant it was gone. It made no sound.The odd thing about it is that only one sister and myself recall the event. The rest of my family,( 4 others), although i know they looked right at the object in wonder,can't remember seeing it. I also find it strange that only 2 other people, (that i have found,one on his site, )recall seeing something simular that week around the nashua area.I know for a fact multiple people saw this UFO.Has everyone forgotten????
