By the time of the hearing, Blue Book had identified and explained 95% of the reported UFO sightings. None of these were extraterrestrial or a threat to national security. Brown himself proclaimed, "I know of no one of scientific standing or executive standing with a detailed knowledge of this, in our organization who believes that they came from extraterrestrial sources." Dr. J. Allen Hynek, a science consultant to Blue Book, suggested in an unedited statement that a "civilian panel of physical and social scientists" be formed "for the express purpose of determining whether a major problem really exist" in regards to UFOs. Hynek remarked that he has "not seen any evidence to confirm" extraterrestrials, "nor do I know any competent scientist who has, or who believes that any kind of extraterrestrial intelligence is involved."
