When I was about 13 years, a student of astronomy, interested in aircraft, and the NASA “space program”, I saw a UFO.  I was at that age a model rocket, math, and science enthusiast.  As an adult I graduated with an engineering degree.  On this special day, it was clear and sunny.  It was in the month of July.  The sky was blue with few clouds and maybe 90 F.  The winds were clam.  I first noticed it coming from the North floating towards the South or South Southeast.  Its speed seemed slow but did travel in a straight line of flight.  The object shape was clearly a rectangle.  Note, it was only a two dimensional object - no thickness.  You could not see through it.  Its color appeared as if it were a solid black - no color changes.  It floated along as if it were a plastic sheet one would hold by hand along the short side in front of a strong fan watching the greater length of plastic flutter very very slowly yet perpendicular to the fan face.  It remained level and with no sound, always keeping the same altitude, same speed, and same direction.  I followed it for nearly 20 minutes and was finally unable to continue.  It just continued southward, in the same direction, same altitude, same speed, unabated.  To ascertain a speed relative to ground, I estimate a segment distance of travel of 500 feet.  During that distance it traveled that distance in about 1 minute.  To estimate the size of the UFO, I would compare it to holding in my out stretched something 1.5"x3.0" in size in my hand.  As far as I know I was the only one to see it.
 Comment: Over the years I often wondered if it were nothing more than a plastic sheet floating along.  But anyone experienced in kite flying would know that any flat plastic sheet would not stay aloft parallel to the earth indefinitely as this object.  I felt when watching it as if it were a hole in the sky.  Almost as if I and the homes were being observed.  I was never frightened.
