Unconventional Flying Objects: A Scientific Analysis Paul R. Hill

Paul R. Hill | Researcher Annotated Copy from the Library of Tony Angiola

This copy of Unconventional Flying Objects comes directly from my personal research library and was actively used during several of my investigative projects into advanced aerial phenomena. Paul R. Hill’s work stands as one of the most respected technical analyses in the UFO field, written by a former NASA scientist who applied real physics, propulsion modeling, and engineering principles to the unexplained performance characteristics observed in thousands of witness reports. Hill’s insights laid the groundwork for how many modern researchers interpret craft behavior today.

Throughout this copy, I highlighted sections that were central to my own research. These include propulsion signatures, plasma effects, tilt-to-control maneuvering, trace evidence such as the Ubatuba magnesium fragments, and multiple-witness case studies that show consistent technological behavior. The highlights document areas of interest I identified while studying propulsion concepts, electromagnetic effects, and performance profiles associated with close encounters. These markings reflect genuine research activity, not random underlining, and provide future readers with a clear map of the technical elements I found most relevant during field investigations and historical case reviews.

The book itself remains one of the most important scientific titles in the UFO literature. Hill analyzes lift surfaces, gravity manipulation, high-acceleration movement, and optical effects in a way that bridges engineering and eyewitness testimony. His work continues to influence researchers, aerospace engineers, and historians seeking to understand the physics behind unconventional craft.

As a working reference copy, this book carries the marks of real investigation, giving it a unique provenance that standard copies do not have. It is ideal for readers who want a research focused edition, as well as collectors who value the documented use of a title within active study. The binding remains solid, the cover is clean, and the pages are fully intact and easy to read.

A practical and meaningful research edition of one of the most respected scientific works ever written on UFO performance and propulsion.
