My grandmother lived with us in Dagsboro, Delaware, and had her bedroom on the first floor with big trees outside her window. She would at times call me into her room to watch objects come down near the trees hovering and changing direction and height abruptly. They were nondescript silverish craft. They would drop down near the tops of the trees but move again so quickly and in irregular patterns so that you couldn't see any details. I remember my grandmother telling me that "People say these are just weather balloons from Wallops Island, but weather balloons can't move like this." I've seen pictures of the weather balloons from Wallops Island, and these objects didn't look anything like that. This was over 40 years ago so the details are vague, but my memory of watching them with my grandmother is very strong. Not an important sighting, but enough to make me a believer. Just wanted to supplement your extensive files as these sightings were never reported.
