In 1955, when my father was 18 years old, he and two of his siblings came across a UFO while walking home from a movie theater at night. The craft was cigar shaped, about 8' long, with flashing lights. It was hovering about 2' above the ground, behind some small businesses in a little logging town in Arkansas.
As soon as they came across it, they did a U-turn and never looked back.
My father told me about this when I was a teenager, and never talked about it again. He was a very quiet, conservative, religious person. At the time of the sighting he was in the Navy and home on leave. His siblings were a little younger than him.
