The Report on Unidentified Flying Objects

This is Edward J. Ruppelt's memoir of his role in the seminal US Air Force UFO study projects: Projects Sign, Grudge and Blue Book. According to this account, he coined the acronym 'UFO' and put many of the official procedures for reporting and studying UFOs in place. An enjoyable read, this book captures the feel of working for the mid-20th century US military. He describes the changing attitudes of the USAF about UFOs during the early 1950s: wobbling between denial, ridicule, paranoia, and genuine inquiry.

A key point of this book is to resolve doubts about the military's role. Ruppelt makes a strong case that UFOs weren't a top secret weapons system; the reports were not disinformation by intelligence agencies; nor was there a concerted effort to cover up UFOs by the US government. Ruppelt does recount many times when the brass tried to dismiss reports without investigating them sufficiently. However, this comes across as simply standard-issue military 'cover-your-ass' behavior, not a vast conspiracy.

He gives unique details on some of the most impressive sightings on his watch. These were largely witnessed by highly trained observers such as radar operators, fighter and commercial pilots, astronomers, and other scientists, often during the course of their official duties. The Air Force group that Ruppelt worked for had access to data on top secret balloon launches and test flights, so they were able to sort out which reports could be explained in this way. He consulted with a wide range of scientific specialists, many of whom were in favor of the extraterrestrial hypothesis, and some who were skeptics.

Fully a quarter of the reports were still unexplained after this rigorous filtering. Ruppelt is decidedly agnostic, but open-minded, about the reality behind the 'unexplained' sightings. Unlike Keyhoe, he does

Edward J. Ruppelt (1923–1960) was a United States Air Force officer probably best-known for his involvement in Project Blue Book, a formal governmental study of unidentified flying objects. He is generally credited with coining the term "unidentified flying object", to replace the terms "flying saucer" and "flying disk", which had become widely known; Ruppelt thought the latter terms were both suggestive and inadequate. Ruppelt was the director of Project Grudge from late 1951 until it became Project Blue Book in March 1952; he remained with Blue Book until late 1953. UFO researcher Jerome Clark writes, "Most observers of Blue Book agree that the Ruppelt years comprised the project's golden age, when investigations were most capably directed and conducted. Ruppelt himself was open-minded about UFOs, and his investigators were not known, as Grudge's were, for force-fitting explanations on cases."
