This undated Defense Intelligence Agency briefing gives a status update on the Advanced Aerospace Weapon System Applications contract. According to the briefing, a July 2008 supplemental appropriation provided $10 million to study foreign advanced aerospace weapon threats up to 40 years out, and Bigelow Aerospace Advanced Space Studies won the contract. It rates BAASS performance as excellent, with 26 research reports received by June 2009, and lists report titles, reviewer comments, option year 1 deliverables and a $12 million FY10 budget. It recommends moving the contract out of DIA if it continues past FY10.
This unclassified Defense Intelligence Agency briefing, dated 16 December 2008, reports on the status of contract HHM402-08-C-0072 for Advanced Aerospace Weapon System Applications. The contract covers technical studies of unconventional aerospace weapon systems projected through 2050, in areas such as lift, propulsion, power generation, signature reduction and human effects. It states that Bigelow Aerospace Advanced Space Studies submitted excellent management plans in 12 technical areas and that the program is on track, on schedule and within cost.
This Defense Intelligence Agency contracting notice for the Advanced Aerospace Weapon System Applications Program (solicitation HHM402-08-R-0211) was posted in August 2008. It is a combined synopsis and solicitation for a total small business set aside. The statement of objectives asks for studies of breakthrough aerospace technologies that could shape the foreign threat through 2050, covering lift, propulsion, materials, signature reduction and human effects. Contractor staff need TS/SCI clearance, and the base year plus four option years runs to 2013.
This is an unclassified Defense Intelligence Reference Document (DIA-08-1003-015), dated 29 March 2010. The Defense Intelligence Agency prepared it under the Advanced Aerospace Weapon System Applications (AAWSA) Program, and Rep. Burchett entered it into the House committee record. The paper uses a general relativity metric tensor approach to look at how engineering spacetime might enable propulsion, including warp drives, apparent superluminal travel, reduced effective mass and antigravity. It finds these ideas consistent with physics but far beyond present engineering capability.
This undated Defense Intelligence Agency briefing gives the status of aerospace contract HHM402-08-C-0072 with Bigelow Aerospace Advanced Space Studies (BAASS). It calls BAASS's performance excellent and notes that 26 detailed research reports had been received by 30 June 2009, twice the minimum required. It recommends exercising option year 1, with $12 million requested in the FY10 budget. It also lists report titles such as Warp Drives and Antigravity Studies, reviewer comments, planned deliverables and a note that the program will likely become a SAP.
This is the July 1966 third edition of Dr. Leon Davidson's "Flying Saucers: An Analysis of the Air Force Project Blue Book Special Report No. 14", published by Ramsey-Wallace Corp. It reproduces early Air Force press releases, the 1953 CIA panel report, the 1966 Blue Book release and the full text of the May 1955 Special Report No. 14 with its tables and codes. Davidson also gives his view that the CIA was responsible for much saucer publicity.
Air Intelligence Division Study No. 203 is a Top Secret analysis dated 10 December 1948, prepared jointly by the USAF Directorate of Intelligence and the Office of Naval Intelligence. It reviews about 210 reported flying object incidents and concludes that some type of flying object has been observed, though its identity and origin cannot be determined. The study treats domestic devices or Soviet aircraft based on German flying-wing designs as possible explanations. It also summarizes selected sighting and radar reports.
This CIA Foreign Broadcast Information Service translation reproduces a report from the Moscow newspaper Trud of 30 January 1985. It describes the crew of Aeroflot flight 8352, a Tu-134 flying from Tbilisi to Tallinn, watching a luminous object about 120 kilometers from Minsk. The object cast beams of light and became a cloud that escorted the aircraft to Tallinn, and controllers reported seeing it too. Commission member N. A. Zheltukhin concluded that the crew had encountered a UFO.
UK Airprox Board report 2013085 examines a 22 July 2013 conflict near Daventry between an A320 inbound to Heathrow and a DH8D inbound to Birmingham, both deviating around thunderstorms. Both crews received TCAS resolution advisories and controllers issued avoiding action, with recorded separation of 1400ft vertical and 2.3nm horizontal. The Board found the Welin controller allowed the DH8D to come into conflict with the A320 by not monitoring its slow descent, and assessed the risk as Category C, with no collision risk.
The UK Airprox Board issued Airprox Report 2013086 on an incident at 1835Z on 19 July 2013, 19.5nm west of Heathrow at FL340. An A320 captain reported a bright silver, cigar or rugby ball shaped object passing a few feet above the aircraft. No TCAS or radar returns were found, balloon releases were ruled out, and the Board judged a sun reflection off distant aircraft possible. Too little information allowed a meaningful finding, so the cause was recorded as a sighting report, risk category D.
This case resolution from the All-domain Anomaly Resolution Office (AARO), U.S. Department of War, is dated 8 September 2025. It reviews 17 minutes and 30 seconds of infrared footage recorded on 23 October 2017 by an aerostat blimp above Al Taqaddum Air Base, Iraq. AARO concludes with high confidence that the object showed no anomalous behavior and was consistent with a cluster of fully and partially inflated balloons drifting with the wind. It rejects a partner's suggestion that the object was a camouflaged quadrotor drone.
This is a short State Department cable from the American Embassy in Tunis to the American Embassy in Algiers, dated March 1975. It was also sent to the Secretary of State in Washington, the Embassy in Rabat and US military European commands, and is filed among National Security Agency records. The cable says Tunisia has had no recent reports of UFO sightings. It adds that the embassy can shed no light on the phenomena described in the referenced telegram.
This FAA daily record of facility operation (Form 7230-4) comes from the Anchorage Air Route Traffic Control Center (ZAN) and is dated 11-17-86. It was released through The Black Vault. Most entries cover routine operations, including SIGMETs, radar outages and NOTAMs for the Mt. Pavlof eruption. The log also records that JL1628, a 747 bound for Anchorage, reported traffic at FL350 with white and yellow strobes that appeared to pace it. Controllers had intermittent radar contact but identified no known traffic, and the Washington ROC was briefed.
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.
The All-domain Anomaly Resolution Office (AARO) of the U.S. Department of Defense issued this case resolution on 8 May 2023. It covers three infrared videos that theater UAV operators recorded over the Middle East and the Mediterranean Sea in 2022 and 2023, which appeared to show anomalous propulsion wakes. AARO concludes that each apparent wake was a sensor artifact. One object was matched to a military aircraft and another to an Airbus A380 airliner, while the rest were probably prosaic aircraft.
This is volume 1 of Autos Findos 908/1997, a military police inquiry (IPM No. 18/97) opened on 29 January 1997 by the commander of the Brazilian Army's Escola de Sargentos das Armas in Três Corações. The inquiry targeted the book "Incidente em Varginha" by Vitório Pacaccini and Maxs Portes, which an officer said spread false claims harmful to the Armed Forces. The volume includes a May 1996 sindicância in which soldiers testified that nothing unusual happened when EsSA trucks traveled to Varginha for routine maintenance, along with pages copied from the book.
This second volume of a Brazilian military court case file, archived by the Superior Tribunal Militar in 1997, holds the Army's Military Police Inquiry into the book "Incidente em Varginha" by Vitório Pacaccini and Maxs Portes. The file reproduces pages of the book, including the claimed 1962 abduction of soldier Geraldo Bichara at the sergeants' school in Três Corações. The military prosecutor called the claims of a 1996 creature capture untrue but found no crime, and the judge ordered the case archived in July 1997.
This Defense Documentation Center report (ADA068988) reproduces a paper Thomas E. Bearden prepared for the 1979 MUFON Annual Symposium. It carries a public-release distribution statement. Bearden is a retired Army lieutenant colonel and nuclear engineer. The paper proposes a speculative mind and matter model built on a claimed fourth law of logic and hyperspatial frames. It argues that the collective unconscious can materialize thought forms under Cold War stress, and it fits major UFO waves and U.S. cattle mutilations since 1973 into that model.
This Black Vault compilation contains a September 1997 reply from the Office of the Assistant Secretary of Defense to John Greenewald's FOIA request, enclosing its UFO records. The enclosures include a Navy information sheet dismissing the Philadelphia Experiment and an Air Force UFO fact sheet listing 12,618 Project Blue Book sightings, 701 of them unidentified. They also include the National Academy of Sciences review endorsing the University of Colorado report and the concluding pages of a 1994 Air Force Roswell report attributing the wreckage to Project MOGUL.
This NICAP-hosted file reproduces USAF Project Blue Book records on a radar and fighter intercept near Bellefontaine, Ohio, on 1 August 1952. Ground radar near Wright-Patterson AFB tracked an object moving at 400 knots. Two F-86s from the 97th Fighter-Interceptor Squadron were sent to intercept it and filmed a silver round object, but the gun camera film was too indistinct. The file includes a completed radar data sheet, a request from the Air Technical Intelligence Center, and a memo about releasing film frames to TRUE magazine. Early analyses ruled out a balloon, but a later conclusion identified the object as an upper air research balloon cluster.
This NICAP-hosted compilation of USAF Project Blue Book records covers the radar-visual intercept of 1 August 1952 near Bellefontaine, Ohio. It holds a press clipping, the ATIC case summary, correspondence between the Air Technical Intelligence Center and the 664th AC&W Squadron, and a completed radar data sheet. Two F-86s from Wright-Patterson took gun camera film of the object. The early evaluation lists it as unknown, but other pages attribute the sighting to a jet on radar and a research balloon seen by the pilots.
This Project Blue Book case file covers the 7 January 1948 incident at Godman Field, Fort Knox, Kentucky, which the file itself calls the famous "Mantell case." It holds control tower witness statements describing a large, bright object and the three P-51s sent to pursue it, whose flight leader, Mantell, stopped answering after climbing past 15,000 feet. It also includes weather data and Air Materiel Command correspondence. One analysis concludes that the object was not Venus and that the sighting must be considered unexplained.
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 compilation of US Air Force Project Blue Book records covers the Exeter, New Hampshire sighting of 3 September 1965. It includes the Pease AFB initial report, Eighth Air Force details on the operation "Big Blast" B-47 flights, and letters from Patrolmen Eugene Bertrand and David Hunt disputing the aircraft explanation. There is also correspondence with John G. Fuller and a 1965 Pease AFB request for speakers. Blue Book listed the sighting as unidentified because no aircraft could be placed in the area at 0200.
This NICAP compilation of USAF Project Blue Book records covers the 3 September 1965 sighting near Exeter, New Hampshire. It holds signed statements from patrolmen Eugene Bertrand and David Hunt and from Norman Muscarello, the officers' UFO data sheets, and press clippings. It also includes the Air Force evaluation, which cites B-47 activity from Pease AFB during Operation Big Blast. The Air Force judged conventional aircraft a possible cause but listed the case as unidentified for statistical purposes.
This NICAP compilation contains a report dated 15 September 1965 from NICAP investigator Raymond E. Fowler to Project Blue Book on UFO sightings in the Exeter, New Hampshire area on 3 September 1965. It includes newspaper clippings, a summary sheet, and signed data sheets from Exeter patrolmen Eugene Bertrand and David Hunt, who with Norman Muscarello saw a silent, house-sized object with pulsating red lights over a field on Route 150 in Kensington. Fowler judged the reports probably genuine.
This file, from NICAP and CUFOS, collects US Air Force Office of Special Investigations records from 1949 on a Project Grudge special inquiry into a sighting at Rogue River, Oregon, on 24 May 1949. NACA Ames Laboratory employees Gilbert Rivera and Don Heaphy described a silvery pancake-shaped object about 30 feet across that sped off like a jet. An annotated analysis that follows rejects the radar kite explanation and concludes that the case must remain unexplained.
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 Project Blue Book microfilm case document from the U.S. Air Force, released through the Internet Archive, covers files 1377 and 1415 dated July 7, 1952. It records CPO Delbert C. Newhouse's two photos of a group of objects milling about in rough formation, taken 7 miles north of Tremonton, Utah, at 1110 MST on 2 July 1952 after his wife noticed them. The record notes there were no reference points and that the images showed no detail. It gives the explanation as pillow balloons or birds.
This is an Air Intelligence Information Report dated 22 July 1952 and prepared by Capt. Benjamin L. Berkon, USAF Director of Intelligence, Headquarters Command. It records interviews with control tower operators at Washington National Airport about unidentified objects on 19 and 20 July 1952. Five unidentified targets appeared on radar over Andrews Air Base, and Andrews tower confirmed seeing three objects. Controllers also saw an orange disk, and a Bolling AFB tower operator saw a roundish object drifting low in the sky.
This undated NICAP (Barry Greenwood) release reproduces Blue Book radar pages 968 to 970. They contain an unclassified report by Senior Controller Harry S. Barnes of the Washington Air Route Traffic Control Center on the targets seen overnight on July 19 to 20, 1952. Barnes describes eight or more slow-moving radar targets and an orange object near Andrews seen by tower staff. He also records pilot reports of lights and says it was unclear who should report the targets or order an intercept.
This Brazilian Navy General Staff report, released via NICAP, examines unidentified flying objects sighted at the Island of Trinidad between 12/5/57 and 1/16/58. It gathers statements from the oceanographic station commandant, CC Bacellar, and from photographer Almiro Barauna, who took photographs aboard the ship Almirante Saldanha. The negatives were examined by DHN and Cruzeiro do Sul technicians, who found no sign of later montage. The report concludes that the testimony is fallible but admits there are indications that UFOs exist.
This undated Central Intelligence Agency document is a set of briefing notes for Walter N. Elder about an unidentified object flying near Puerto Rico in November. It says the destroyer U.S.S. Gyatt tracked a radar contact at more than 3,800 knots on 19 November. The object paced an F-8 Crusader and then climbed away. The pilot described a delta shaped object about the size of a jet fighter. The notes say ONI had no further information.
This undated brochure from Naval Air Station Fort Worth Joint Reserve Base describes the military airspace its tenant units use for training. It explains Special Use Airspace, Military Operating Areas and Military Training Routes. It then details the Navy-owned Brownwood MOA and the Air Force-owned Brady MOA, which lie about 70 nautical miles southwest of the base and are scheduled by the 301st Fighter Wing. The brochure also profiles the F-16C, FA-18 and C-130 aircraft stationed there. It contains no UFO material.
This Wikimedia Commons file holds a transcribed parish burial register from 1764, written in French. The poorly transcribed text records several burials. One is dated 3 June 1764 and mentions a victim taken by the beast ("la bette"). Another is dated 18 September 1764, and a third records a sudden death. The legible text does not clearly give Jeanne Boulet's name, although the title says the record is hers.
This Brazilian Air Force (FAB) envelope, released through The Black Vault, collects UFO material from the 1950s to 1972. It includes a 1971 Second Air Zone report on luminous objects over Recife and Olinda, with newspaper clippings, and an informant report on an oval object over Varginha and Três Corações. It also holds witness letters from Guaratinguetá, a clipping on a suspected Navy weather balloon at Barra de Itapemirim, and pages from CICOANI's December 1971 field investigation manual with size-estimation tables.
This CIA document, released through The Black Vault, holds Foreign Press Note FB PN 90-123. It is document 4 of 9 in a set of concatenated PROD reports from 1988 to 1994. The note reviews Soviet press coverage of UFO sightings. It centers on a RABOCHAYA TRIBUNA report of 21 March sightings near Pereslavl-Zalesskiy, with pilot and radar accounts and comments from Colonel General Igor Maltsev of the Air Defense Forces. It also summarizes other Soviet articles, including the Belgian sightings and a Japanese expedition to Tunguska.
This Central Intelligence Agency dossier on Cuban exile leader Manuel Ray Rivero was released in 2023 under the President John F. Kennedy Assassination Records Act. It contains biographical sketches of Ray as Castro's Minister of Public Works and later leader of the MRP and JURE, a 1965 report on his views of anti-Castro tactics, a Spanish report on his 1965 Madrid visit, and 1977 cables answering an FBI request. Those cables note he was declared persona non grata in Jamaica in December 1976.
This 22 November 1989 report, released as CIA document 0000042346, covers a wave of Soviet media stories about UFO sightings across the USSR. It says a permanent UFO study center has been set up in Moscow. It reviews claims about the Hill 611 crash at Dalnegorsk, a pilot injury over Borisov, the Voronezh park landing and an Omsk sighting reported by a military officer. The report also sets skeptics, who point to rocket launches, ball lightning and mass hysteria, against enthusiasts who compare Dalnegorsk with Roswell.
This FBIS translation of an article published in the Moscow newspaper TRUD on 30 January 1985 reports a UFO sighting by the crew of Aeroflot Tu-134 Flight 8352, commanded by Igor Cherkashin, about 120 kilometers from Minsk. The crew saw a light beam, then a green cloud that paced the aircraft to Tallin. Minsk controllers, a Leningrad crew and the Tallin radar also saw or tracked it. N. Zheltukhin of the Commission on Aerodynamic Phenomena concluded that the crew had dealt with a UFO.
This CIA document, released through The Black Vault, holds F. C. Durant's memorandum of 16 February 1953 on the Office of Scientific Intelligence Scientific Advisory Panel on Unidentified Flying Objects, which met from January 14 to 18, 1953 under Dr. H. P. Robertson. The panel found no evidence of a direct threat to national security. It rejected the Navy analysis of the Tremonton film and recommended an educational program. The file also contains an Air Force statistical study summary from 1955 that calls advanced unknown technology highly improbable.
This CIA archives copy, released in 2026, holds Project Blue Book Special Report No. 14 (Analysis of Reports of Unidentified Aerial Objects). The Air Technical Intelligence Center at Wright-Patterson Air Force Base issued it on 5 May 1955. The study reduced about 4,000 sighting reports from 1947 to 1952 to IBM punched cards, with 3,201 cases charted, and applied chi square tests to compare known and unknown sightings. It concludes that it is highly improbable the reports represent technological developments beyond present-day scientific knowledge.
This is a CIA History Staff monograph by Gregory W. Pedlow and Donald E. Welzenbach, written in 1992 and approved for release in 2011. It covers the CIA's manned overhead reconnaissance program from 1954 to 1974 and its two aircraft, the U-2 and the A-12 OXCART. It follows their development, the overflights of the Soviet Union, the downing of Francis Gary Powers in 1960, and later operations. One section is titled "U-2s, UFOs, and Operation BLUE BOOK."
This National Security Agency release is a COMNAVSECGRU report of a visual sighting. The report is undated, and the document was declassified by COMNAVSECGRU on April 30, 1979. It describes a light that pulsed at first and then gave off concentric rings, followed by a reddish-green beam like a searchlight. The beam and core then formed a nebulous cloud that drifted south and faded after about 14 minutes. Weather data are included, and an electrical storm was noted over a city whose name is garbled.
This material from the Haines papers at the American Heritage Center contains US Air Force Office of Special Investigations reports from November 1949. They cover a special inquiry into unconventional aircraft. An Eastern Air Lines captain was interviewed in Atlanta on 6 October 1949. He described a wingless, cigar-shaped object with two rows of lighted windows and a red flame, seen at 0340 on 23 July 1948 southwest of Montgomery, Alabama. A follow-up report closed the inquiry.
