The South St. Louis Ring: Eyewitness Sighting, Cloaking, and the Evolution of Warp-Drive Concepts

To the point

An eyewitness account of a late-1970s circular, light-ringed craft describes a cloaking field visible only from inside and frames the sighting as tied to speculative warp-drive physics and transformation optics, tracing ideas from Alcubierre through Pfenning, Ford and Harold White to later proposals by Erik Lentz, Bobrick and Martire and researchers like Puthoff and Forward, while noting uncertainties about deliberate exposure and selection effects.
