3 feet above treetops, trees 50 to 80 feet tall. brilliant silver drew our attention. a rectangular viewing window showed an entity with extended “arms” to a panel and the entity, human like, turned towards us. we did not feel threatened and were impressed with an overwhelming feeling or vibe of “not yet” or of “loss”. the craft moved at a normal “walk speed” , was not in a hurry even as it turned east and away from us. the silver brilliance of the craft was like nothing we had ever seen and have not since.There was no noise except when it turned east and a very low hum was felt, more than heard as it turned away. being a construction technician i estimated the craft to be 50 feet long, 15 feet wide, and 9 feet top to bottom.Our distance away was 150 -200 yards away. yes, it has been 40 years but i finally found someplace or someone to tell about this.
