Milwaukee-- one winged, silent, brightest lights, huge, 1993

I was a passenger in a vehicle with three other people (a friend, his brother, his mom, me).  We were traveling from Milwaukee south to Kenosha on a road running parallel and just east of I-94.  We first noticed what we thought was a plane flying very low with extremely bright lights flying directly at us.  The plane took a long time to reach us and eventually we pulled over to witness this flyby.  The three lights were so bright.   We pulled the car over and turned off the engine.  The craft was flying around 100 ft off the ground—amazing.  It was all-white, one winged, no windows, and had to be two stories thick but rounded with slightly swept back wings.  The most amazing part was it made no noise!  It looked like it weighed 300 tons, as big as a passenger jet but much thicker.  Moreover, it was flying no more than 15 mph.  I had a good long look at it 100 feet away.  It flew right along the west side of the road.  By far the most amazing thing I’ve ever seen.   I’ve told the story many times with a response most often of “hm.”  I have yet to look on the site but more people had to see this thing.  It was flying in the direction of the Mitchell airport, so I’ve always wondered if it landed.
