I was at the outdoor movie(drive-in) with my daughter. We were sitting on lawnchairs outside the car, when I noticed out of the corner of my eye a fairly low dark object moving through the sky. It was almost dark out(9:45 p.m. central time) I pointed it out to my daughter and she was somewhat scared. Craft appeared as a dark structured shape with more of a barely visible outline. No shape could be confirmed. I initially thought the shape was triangular, but after thinking long about it I cannot confirm. It was like a shadow that was flying. Craft had no lights. Craft was flying North, slightly Northwest. It was kind of a hazy sky but we watched it for about 5 seconds before it was no longer visible. Craft was fast but not unbelievably fast. I Had a strange initial feeling as I seen it. My brain told me that is what a craft flying in the dark with no lights looks like no big deal. Then a fraction of a second later I was thinking this was not normal. No sound was heard from it. A plane that size should of been heard even with the radio on outside for the movie. It was that close.
