Elaine Douglass: Invisible UFOs Presents Case Reports and videos Suggest the Reality

This presentation covers sighting reports, witness testimony, and a video, which combine to suggest that alien aircraft have the capability to be invisible. We will examines reports from World War II to the present, which illustrate invisibility to radar, optical invisibility, and directional optical invisibility according to the angle of observation. Elaine also considers events associated with chemtrails and cattle mutilations, as well as abductee reports in which invisibility is inferred. In addition, she presents and discusses the 1989 Durea sequence, which portrays a craft transitioning into and out of an optically invisible state, and examines a proposed technical mechanism to account for UFO invisibility, the bending of light in a gravitational field.
