Yes, I have.
I was in college, and all of us girls were going out somewhere....in back of our dorm was a cornfield.....we were used to seeing crop dusters go back and forth, and it definitely wasn't that. It was a cigar shaped thing, and it was going very slowly across the sky and then it just stopped and hovered briefly...then poof! It was gone. We all saw it, so I know I wasn't the only one. It was really weird.
