 CONT: During the beginning scenes, you see the train approaching the  Obercassel Bridge in a gentle right curve. Then you see the M24  Chaffee tanks and their support running for the Bridge. Then the  error appears: The armor is seen on the river road, but the negative  is reversed. Names on the tanks are reversed, the trucks steering  wheel is on the right side, and the train is now making a gentle  *left* curve onto the bridge. Reversal ends as the sequence ends  with the explosion/destruction of the bridge.
