UFOs AND THE FOURTH DIMENSION: A RE-EXAMINATION

This document consists of articles from the Flying Saucer Review (FSR). The first section features a personal account and sketch by Antonio Ribera regarding a sighting in Spain on December 3, 1984, of a large, metallic, delta-shaped object with lights. The primary article, written by Luis Schoenherr, re-examines the UFO phenomenon through the lens of the 'fourth dimension.' Schoenherr, a long-time ufologist, argues that the apparent dematerialization and reappearance of UFOs, as well as their metallic appearance and radar signatures, can be explained by the hypothesis that these objects exist in a fourth dimension and only partially project into our three-dimensional space. He discusses various possibilities, including that UFOs are time machines or craft from other dimensions, and addresses the reports of 'contactees' who claim to see beings without space suits. The document also includes a secondary article by Paul Whitehead, which explores the intersection of quantum mechanics, parallel universes, and faster-than-light travel (tachyons) as potential scientific frameworks for understanding UFO propulsion and communication. The text concludes with a list of UFO-related publications and a compilation of historical sighting reports.
