Looking at stars at about 3 am- 2 adults, 2 teenage children. felt a weird pressure and looked over lake. there was a craft 2 miles away about 100 feet over the water. was black-no lights. moved slowly across the water directly over our heads. no sound. had rounded edges with what looked like windows. had multiple angular pieces on undercarriage, but did not look like landing gear. continued on same path. saw for about ten minutes.
