The Report on Unidentified Flying Objects is a book by Edward J. Ruppelt which described the study of UFOs by United States Air Force from 1947 to 1955. Ruppelt was a United States Air Force officer 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." Because Ruppelt was the central axis of the government's investigation the book provides a unique insider look at how the government's efforts functioned.

Edward James Ruppelt was a United States Air Force officer known for his participation in official administrative studies of unidentified flying objects. These reports go into a number of specific cases in considerable detail.

Project Blue Book was a U.S. government investigation of Unidentified Flying Objects - UFOs. One of the men working on the project was decorated U.S. Air Force officer Edward Ruppelt, and this book contains the findings. The ideas surrounding UFOs were stoked by popular imagination; flying saucers, alien visitation or even abduction, and strange phenomena such as lights or aircraft moving rapidly in the sky. Following World War II, the idea that aliens were regularly appearing in spacecraft, coupled with abundant reports of unexplained objects in the sky, prompted a series of investigations by governments. Project Blue Book was among the most notable, led by Josef Allen Hynek and staffed by officers such as Edward Ruppelt - both of whom were open-minded when identifying these unusual phenomena. Ruppelt's explanations are thorough, explaining what he and his team uncovered in detail over the course of 1952-1954. Finding nothing conclusive in support of UFOs as alien spacecraft, he quotes fellow officer Andy Flues: "Even taking into consideration the highly qualified backgrounds of some of the people who made sightings, there was not one single case which, upon the closest analysis, could not be logically explained in terms of some common object or phenomenon."

The Report on Unidentified Flying Objects 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, The Report on Unidentified Flying Objects captures the feel of working for the mid-20th century US military. Ruppelt 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 The Report on Unidentified Flying Objects is identifying 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 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. "The Report on Unidentified Flying Objects" is a must read for anyone interested in UFOs.

The meticulous account of the top military brass on UFOs in the United States. Written and documented by the former head of the Air Force Project Blue Book, the federal organization in charge of a formal government study of UFO's.
