The craft was first heard/felt as though it made a light bass like sound that remained constant. no lights. strange box like indentations on bottom of craft of different depths. it moved very slow, maybe 10 mph, almost a hover. clouds were low, thin and light that night. i would describe the size as at least (3-5) 747 airplanes in a triangle shape. it also was very thick, about two stories. the craft was dark black almost matte, not shiny. we live on a lake which we walk our dog every night, this is where small planes start their decent to a small local airport runway. the airport is about 2 miles from the house. cessna sized planes come in during the day giving us a base line to pull a size comparison. also macdill airforce base is about 10 miles east of this sighting.
my wife was the first of us to notice and we have talked about this many times agreeing on the object.
