In November 1896 people in Sacramento and then San Francisco and Oakland reported a lighted airship moving across the night sky. In early 1897 reports spread east through Nebraska, Kansas, Iowa, Illinois and Texas, often with tall tales of inventors and crews. The line on the map joins the main clusters of reports in date order. It is a wave of sightings, not one object.

Explanation

No powered airship capable of such flights existed. Reports are attributed to newspaper hoaxes (some papers invented stories outright), bright planets such as Venus, hot-air "fire balloons" and pranks.
