This confidential FBI office memorandum, sent from the San Antonio office to the FBI Director on January 31, 1949, and held in a NICAP copy, reports on Fourth Army intelligence conference discussions of unidentified aerial phenomena. It covers the July 1948 Eastern Airlines sighting over Montgomery, Alabama, and a concentration of green light sightings near Los Alamos, New Mexico. It notes that little concrete information has been obtained, and that G-2 and OSI are investigating while this office is not.
This NICAP extract reproduces the statement of Dr. Robert M. L. Baker, Jr., a Computer Sciences Corporation scientist and UCLA engineering faculty member, to the House Committee on Science and Astronautics symposium on unidentified flying objects on July 29, 1968. Baker reviews his analyses of the Utah, Montana, Venezuela and Vandenberg films. He argues that current radar and optical sensors are poorly suited to detecting anomalistic phenomena and urges a well-funded, long-term interdisciplinary research program. The extract ends with panel discussion including Hynek and Hall.
This document is a NICAP-hosted table of AFOSI raw data summarizing 209 sightings of unknown aerial phenomena, listed from January 1943 through May 1950. Most reports come from New Mexico sites such as Los Alamos, Sandia Base, Albuquerque, Alamogordo and Vaughn, with others from Camp Hood, Texas, and Arizona. For each sighting it records the observers, the reliability rating, direction, color, duration, shape, speed and how the object disappeared. It sorts the cases as green fireball phenomena, disks or variations, or probable meteors.
This NICAP compilation gathers Air Force Project Blue Book and related records on a 24 April 1949 sighting three miles north of Arrey, New Mexico, where a balloon crew from White Sands Proving Ground tracked a white ellipsoid object with a theodolite for about 60 seconds. It includes the observer's statement, a Project 10073 record card concluding UNIDENTIFIED, a 17 May 1949 OSI special inquiry report from Kelly AFB, and a completed investigation questionnaire. It also contains extracts from the Project Grudge report, including Dr. Hynek's incident index.
This document is a 20 May 1949 cover letter from the Commanding Officer of the Navy's Special Devices Center at Sands Point, Long Island, to the Chief of Naval Operations (Office of Naval Intelligence), with a copy sent to the CIA. It forwards C. B. Moore's statement on an object he tracked by theodolite on 24 April 1949, three miles north of Arrey, New Mexico. Moore describes a white ellipsoid that was seen for about 60 seconds. He concludes that it was not a balloon, and the letter says its motion might indicate controlled flight.
This NICAP compilation gathers National Military Command Center memoranda, DDO updates and OPREP-3 messages from October and November 1975 reporting unidentified helicopters and low-flying aircraft near weapons storage areas at Loring AFB, Maine and Wurtsmith AFB, Michigan, plus radar and visual UFO contacts at Malmstrom AFB, Montana. Pursuit attempts by an Army National Guard helicopter and a KC-135 tanker failed. The file also includes a 1976 USDAO Tehran report on an F-4 encounter, 1965 Blue Book statistics and an American Meteor Society fireball form.
This NICAP compilation lists Project Blue Book cases from June through December 1947. The date it was prepared is not given. Arranged by month, it gives each sighting's incident number, date, location, observer type and the Air Force evaluation. Evaluations include balloons, meteors, aircraft, birds, contrails, hoaxes and insufficient data, and several cases are marked unidentified. Locations include Muroc AFB, Rogers Dry Lake, Emmett, Twin Falls, Phoenix and Newfoundland, and some entries note that the case file is missing.
This NICAP-hosted Blue Book file, credited to Brad Sparks, collects 1949 US Air Force Office of Special Investigations reports on a disc seen over the Rogue River near Gold Beach, Oregon, on 24 May 1949. It includes signed statements from fishing party members, among them staff from the NACA Ames Laboratory at Moffett Field, along with character references and interview forms. The witnesses describe a silvery circular object with a fin that flew silently. Investigators noted that radar test kites might have drifted that far north.
This undated NICAP file holds a handwritten personal statement about a UFO sighting at Edwards AFB, California, around July or August 1964. The writer was senior officer on alert that night. They say the SAGE center in San Bernardino called at about 0200 about UFO reports and asked for an F-106A to be launched, then declined to authorize it. The writer and three others watched a pulsating light turn 90 degrees and climb until it seemed to go out into space. Edwards approach control reported no radar contact.
This National Military Command Center memorandum for record, signed by the NMCC Deputy Director for Operations and made available through NICAP, records phone reports from the NORAD Command Director about unidentified objects near Malmstrom AFB, Montana. Heightfinder radar tracked the objects while personnel at several SAC sites saw lights and heard jet-like engine noise. Two F-106 interceptors were scrambled but could not intercept them, and witnesses said the lights went off whenever the fighters arrived. NORAD ruled out Northern Lights and listed the incident as an unknown fade.
This memorandum for record comes from the Deputy Director for Operations of the National Military Command Center (NMCC), a US Army brigadier general. It records NORAD phone reports of lights, jet engine sounds and height-finder radar returns at Malmstrom AFB and nearby SAC sites in Montana, including over Lewistown. Two F-106 interceptors were scrambled but could not intercept the objects, which reportedly turned their lights off while the fighters were present. NORAD ruled out Northern Lights and carried the incident as a fade remaining unknown.
This NICAP compilation by Dan Wilson gathers Project Blue Book records on the sighting of 24 February 1959, when American Airlines Flight 139, flying from Newark to Detroit, and two United Airlines crews saw three lights over Pennsylvania and Ohio. It includes the record card, pilot statements, Air Force letters and correspondence with an Akron UFO committee. The Air Force concluded that the lights came from three B-47s refueling from KC-97 tankers. Book excerpts disputing Captain Killian's later claims are also included.
This secret Project Blue Book investigation report, numbered T53-11156, covers a combined air-visual, ground-visual, air-radar and ground-radar sighting near Rapid City and Blackhawk, South Dakota, on 5 August 1953. It records interviews with the radar controller and two F-84 pilots who chased a light, checks of weather balloon tracks, and comments on how reliable each witness was. It suggests that a balloon, a star such as Capella, or an equipment malfunction may explain the sighting, but it carries the incident as Unsolved.
This NICAP document reproduces part of a Project Blue Book sighting list and has no date. It covers entries numbered roughly 2656 to 2697 for August, running from Stalingrad, USSR and Centerville, Idaho to Port Moresby, New Guinea and Lewisdale, Maryland. Some case files are marked as missing. The evaluations given include aircraft, meteors, balloons, stars and planets, anomalous propagation and insufficient data, and several entries are listed as unidentified.
This declassified U.S. Air Force file contains the final report of Project Twinkle, dated 27 November 1951 and written by Louis Elterman of the Geophysics Research Division, together with related correspondence. The project was set up to investigate the green fireballs and other light phenomena around Holloman AFB and Vaughn, New Mexico, and it was run with Askania cameras. The report calls its findings essentially negative and recommends no further funding. In March 1952 the Directorate of Intelligence declined to declassify it.
This NICAP copy of a declassified DIA file pairs a routing slip from Louis E. Foster of DIA with a message the US Defense Attache Office in Tehran sent on 23 September 1976, signed by Col. Frank B. McKenzie. The message reports that two Imperial Iranian Air Force F-4s were scrambled on 19 September 1976 after citizens in Tehran reported an object in the sky. It describes lost instruments and communications, smaller objects separating from the main one, a possible landing, and plans to check the site for radiation.
This NICAP-hosted compilation of Project Blue Book records covers the Air Force investigation of policeman Lonnie Zamora's 24 April 1964 sighting at Socorro, New Mexico. It includes Foreign Technology Division teletypes, a resume and narrative of the sighting, Capt Hector Quintanilla's memos, and letters to Project Cloud Gap and the FAA. Investigators found no radiation, no foreign material in soil samples, and no helicopter or radar explanation. They concluded that a real object was seen, possibly a VTOL or lunar module type vehicle, and left the case open.
This is a two-section unclassified Air Force message sent on 5 August 1965 by the 2854th Air Base Group at Tinker AFB, Oklahoma, to Wright-Patterson AFB, USAF and other recipients under AFR 200-2. It reports four bluish-white objects that a control tower supervisor watched through binoculars for about 1.5 hours on 2 August 1965. The 746th squadron made radar contact with one object near Norman. The message notes many sightings across the Oklahoma City area and gives weather balloons and/or known aircraft as the preliminary cause.
This NICAP compilation holds twelve pages of FBI teletypes, airtels and memoranda from April and May 1964, exchanged between the Albuquerque office and the FBI Director. They cover the April 24, 1964 Socorro, New Mexico sighting, in which an oval object with a red insignia left four indentations and burned patches. A second report from La Madera involved a burning tank-shaped object. The FBI conducted no investigation of its own and kept liaison with the military, whose officers had no explanation for either incident.
