Brief

In the early hours of the third of September 1965, an eighteen-year-old hitchhiker and two Exeter, New Hampshire police patrolmen reported a large, silent object carrying five pulsating red lights manoeuvring at roughly one hundred feet over a field three miles south-west of the town.

Briefing

In the early hours of the third of September 1965, an eighteen-year-old hitchhiker walking Route 150 outside Exeter, New Hampshire, reported a group of five bright red lights descending toward him over a house about a hundred feet away [15]. Within the hour two patrolmen of the Exeter Police Department had seen the same lights over the same field and filed signed statements [16][17]. The US Air Force investigated the case under AFR 200-2, proposed a Strategic Air Command exercise as the cause, tested that hypothesis against Eighth Air Force records, and abandoned it. The Project 10073 record card for the case carries the conclusion “UNIDENTIFIED” [2].

Sequence of events

The night of the second to third of September 1965

  • Circa 02:00. The teenage witness, hitchhiking on Route 150 about three miles south-west of Exeter, stated that “a group of five bright red lights appeared over a house about 100 ft from where I was standing”, in a line at about a sixty-degree angle, “pulsating 1,2,3,4,5,5,4,3,2,1”. He watched them for about fifteen minutes and reported that at one point “they seemed to come so close I jumped into a ditch to keep from being hit” [15].
  • 01:00. Separately, Patrolman Eugene F. Bertrand Jr. stated that on the Route 108 by-pass he had found a woman parked at the roadside who “stated a light had been following her and had stopped over her car”. He remained about fifteen minutes, saw nothing, and returned to the station — where he found the teenager [17].
  • Circa 02:45. Bertrand drove the youth back to the field, parked and killed the cruiser lights. In his statement: “When we had gone about 50 ft a group of five bright red lights came from behind a group of trees near us. They were extremely bright and flashed on one at a time… At one time they came so close I fell to the ground and started to draw my gun. The lights were so bright I was unable to make out any form. There was no sound or vibration but the farm animals were upset in the area and making a lot of noise” [17].
  • Circa 02:55. Patrolman David R. Hunt stated that he received Bertrand’s radio call, arrived, and “observed a group of bright red lights flashing in sequence… about ½ mile over a field to the South East”, which moved off south-easterly and disappeared, remaining at an estimated altitude of about one hundred feet [16][17].

The official investigation, September 1965 – March 1966

  • 15 September 1965. Headquarters 817th Combat Support Group (SAC) at Pease AFB filed the initial AFR 200-2 report: object “Round”, apparent size “Baseball”, “Bright red”, “Five red lights in a row”, “Lights were close together and moved as one object”, at approximately one hundred feet, moving through an arc of 135 degrees and departing on a magnetic heading of about 160 degrees. Weather was recorded as “clear with no known weather phenomenon” with “a 5 degree inversion from surface to 5000 ft”. Both patrolmen were rated “Reliable” [12][13].
  • The investigating officer, Maj. David H. Griffin, wrote: “At this time have been unable to arrive at a probable cause of this sighting. The three observers seem to be stable reliable persons, especially the two patrolman… Pease AFB had 5 B-47 aircraft flying in the area during this period but do not believe they had any connection with this sighting” [14].
  • 19 October 1965. The Foreign Technology Division told Pease AFB that Exeter was the one report of the past year that could not be evaluated without further investigation, that the “Fur Trapper” and “Down Date” refuelling areas were closed 03/0500Z–03/0600Z for Eighth Air Force operation “Big Blast”, and: “It is our belief that aircraft from this operation and various stars and planets were the causes of the various reports on the night of 2-3 September from this area” [3][4].
  • 24 November 1965. Headquarters Eighth Air Force replied that Big Blast “Coco” was a SAC/NORAD training mission flown on the second and third of September 1965; that by 03/0430Z the operational portion was complete; and that ten B-47s from Pease AFB were estimated to reach their initial approach fix between 03/0444Z and 03/0535Z — roughly a quarter to one until half past one local — with Exeter lying inside the recovery traffic pattern [5].
  • Blue Book chief Maj. Hector Quintanilla Jr. wrote to Bertrand and Hunt asking whether either had seen aircraft during the period, noting that if they had, “this would tend to eliminate this air operation as a plausible explanation for the objects observed” [6].
  • 11 January 1966. FTD advised Hq USAF that the aircraft information “conflicted with the time of the sighting and eliminated these aircraft as a possible evaluation of this incident”, and that while earlier sightings that night were attributed to Big Blast “Coco”, “the subsequent observation by Officers Bertrand and Russel occurring after 2 A.M. are regarded as UNIDENTIFIED”. The document reads “Russel”, not “Hunt” [9].
  • 9 February 1966. Lt Col John P. Spaulding, Office of Information, wrote to the two patrolmen: “Based on the additional information you submitted to our UFO investigation office at Wright-Patterson Air Force Base, Ohio, we have been unable to identify the object you observed on September 3, 1965” [10].
  • 3 March 1966. An FTD summary records that Dr J. Allen Hynek was consulted, that Pease AFB was asked to interrogate the B-47 crews, and that a TWX received on the eleventh of February 1966 “indicated that no unusual sightings were made by crews during the time period of the unidentified flying object report” [11].

Documentary record

The Air Force case file is held by the US National Archives as the file unit “Exeter, New Hampshire, September 1965” (NAID 302543878), 131 pages, within the series “Sanitized Version of Project Blue Book Case Files on Sightings of Unidentified Flying Objects”, Record Group 341, microfilm publication T1206 roll 57 [1]. Within it sit the Project 10073 record card — source “Civilians (MULTIPLE)”, multiple objects, a two-hour observation, ground-visual, no photos, no physical evidence, conclusion “UNIDENTIFIED” [2]; the Pease AFB initial report of the fifteenth of September 1965 with Maj. Griffin’s conclusion [12][13][14]; three signed witness statements [15][16][17]; and the FTD/Blue Book correspondence chain from October 1965 to March 1966 that shows the aircraft hypothesis proposed, tested and abandoned [3][4][5][6][9][11].

Also filed are the officers’ own rebuttals. Writing to Quintanilla on the second of December 1965, Bertrand and Hunt stated they “saw this object at close range, checked it out with each other, confirmed and reconfirmed the fact that this was not any kind of conventional aircraft, that it was at an altitude of not more than a couple of hundred feet”; that immediately after it disappeared “we did see what probably was a B-47 at high altitude, but it bore no relation at all to the object we saw”; and that their observation was “nearly an hour after 2:00 AM”, which they argued eliminated Big Blast [7]. In a further letter of the twenty-eighth of December 1965 they wrote that the craft “was not more than 100 feet in the air, and it was absolutely silent, with no rush of air from jets or chopper blades whatever. And it did not have any wings or tail. It lit up the entire field, and two nearby houses turned completely red. It stopped, hovered, and turned on a dime” [8]. These are witness assertions, not findings of the investigation, and the archive records them as such.

A civilian investigation by Raymond E. Fowler, Chairman of the NICAP Massachusetts Subcommittee, was copied to Blue Book on the third of October 1965 and filed with the case [18]. Fowler reported the sighting as occurring over the field of Carl Dining in Kensington, New Hampshire, on Route 150 about three miles south of Exeter; that the moon had set and the sky was “studded with stars”; that no interference was noticed on the police radio and no scorch marks or indentations were found in the field; and that horses in a nearby barn “whinnied and kicked their stalls” while a dog across the road barked furiously [21][22]. He recorded Bertrand’s estimate of the object at closest approach as the apparent size of a “grapefruit” held at arm’s length, and Hunt’s — arriving later and further away — as a “baseball” [21]. Fowler wrote that Bertrand “stated that it was definitely not an airplane or helicopter and that in his opinion that it was an intelligently constructed and operated vehicle”, while neither officer would venture an opinion as to what the object was [22]. That is an opinion recorded by a civilian investigator, and carries no evidential weight here.

The Condon Report of 1968 indexes the case and records the hypothesis put forward by Philip J. Klass, that the Exeter lights were a form of coronal discharge or plasma associated with high-tension power lines, Exeter being close enough to the sea for salt to form on the wires and the summer having had little rainfall to wash it away [23]. The same report records two criticisms of that hypothesis: “(1) that other seacoast towns with high tension wires did not report UFO activity during the drought period, and (2) the luminosity, although near the wires, was occasionally some angular distance away” [23]. The Condon Report also notes that the sightings were “made the basis of a brief article in the Saturday Review for 2 October 1965, and later of a book, Incident at Exeter by John G. Fuller (1966)”; a copy of the Saturday Review article is attached in the Blue Book file [24][6].

Open questions

  1. The woman motorist Bertrand encountered on the Route 108 by-pass is not identified in any primary document. Fowler recorded that Bertrand “did not attach enough importance to the woman’s account to warrant obtaining her name” [22][20].
  2. No Air Force document in the file offers an alternative positive identification for the post-two-a.m. observation. The case was closed as unidentified rather than resolved [9][10][2].
  3. The file does not contain the text of the Pentagon press release that Bertrand and Hunt describe as attributing their sighting to “multiple high altitude objects” and “weather inversion”. Only the officers’ characterisation of it survives in the examined pages [7][8].
  4. Witness ages and exact sighting times conflict between the Air Force report and the NICAP report — Bertrand is given as thirty and thirty-two, Hunt as twenty-eight and twenty-six — and are not reconciled in the file [13][19][21].
  5. The record card gives the aircraft window as 03/0444Z–03/0535Z, while the FTD letter of the nineteenth of October 1965 gives the refuelling-area closure as 03/0500Z–03/0600Z. The file does not explain the difference [2][3].
  6. The frequently repeated claim that Blue Book publicly blamed the sighting on the planet Jupiter is not supported by any page of the case file examined. The Air Force wording located is the generic “various stars and planets” [3].
  7. No photograph or physical evidence of the object exists in the file; the record card marks both “Photos” and “Physical Evidence” as “No” [2].

Status

This file is CONFIDENTIAL — admitted to the archive on the strength of contemporaneous US military documentation: a signed AFR 200-2 report by an investigating officer who found no probable cause, three signed witness statements, a correspondence chain in which the Air Force’s own explanation was tested and withdrawn, and a record card bearing the official conclusion “UNIDENTIFIED” [2][9][10][12][14]. Witness testimony alone would not clear our editorial bar; here the documentary trail carries the case. The reported formation of five pulsating red lights moving as a single body places this file alongside the archive’s other records of luminous spheres and orbs, and its structure — military witnesses, an official file, and a withdrawn conventional explanation — parallels the Rendlesham Forest material, though the two events share no other connection. Updates pending should the Pentagon press release referenced by the patrolmen be located.

Frequently asked

What happened at Exeter, New Hampshire in September 1965?
In the early hours of the third of September 1965, an eighteen-year-old hitchhiker and two Exeter police patrolmen reported a large, silent object carrying five pulsating red lights manoeuvring at roughly one hundred feet over a field about three miles south-west of Exeter, in Kensington. The three witnesses each gave signed statements, which are attached to the US Air Force's investigation report.
Did the US Air Force explain the Exeter Incident?
No. Project Blue Book initially attributed the night's reports to a Strategic Air Command training exercise, Big Blast "Coco", and to stars and planets. When Eighth Air Force records showed the aircraft timings conflicted with the sighting, the Foreign Technology Division advised on the eleventh of January 1966 that the officers' post-two-a.m. observation was "regarded as UNIDENTIFIED". The Project 10073 record card carries the same conclusion.
Who were the Exeter witnesses?
The three primary witnesses were Norman Muscarello, aged eighteen, of Exeter, who was hitchhiking on Route 150 when he first saw the lights, and Patrolmen Eugene F. Bertrand Jr. and David R. Hunt of the Exeter Police Department. Muscarello's name is redacted from his statement in the sanitised file but appears in the NICAP report filed alongside it. The Air Force report rated both patrolmen "Reliable".
Is there a conventional explanation for the Exeter lights?
The Condon Report records that Philip J. Klass proposed the lights were a form of coronal discharge or plasma associated with high-tension power lines, noting Exeter's proximity to the sea and a dry summer that would leave salt on the wires. The same report records two criticisms: other seacoast towns with high-tension wires reported no such activity during the drought, and the luminosity was occasionally some angular distance away from the wires.
