David N. Johnson Gowen Field Idaho Aerial Sighting and Sworn Statement, July 6–12, 1947 (Idaho Daily Statesman Aviation Editor, 8mm Film, CIC Credibility Assessment, Brown-Davidson Joint Field Operation Confirmed)

Summary

Pages 168–171 of Section 2 contain the complete primary-source documentation of aviation editor David N. Johnson’s July 6, 1947 aerial sighting near Gowen Field (Boise Army Air Base), Idaho: the 4AF CIC Incident Report (4AF 1208 I, dated 16 July 1947) assessing Johnson’s credibility and institutional standing, and Johnson’s own sworn notarized statement (signed July 12, 1947, notarized by Geo. L. Flaherty, Ada County Idaho). Johnson observed an unidentified object while conducting an assigned aerial search for the Idaho Daily Statesman, filmed approximately 10 seconds of 8mm motion picture film, described the object rolling to present its edge (appearing as a thin black line), and lost sight of it after it executed a partial barrel roll breaking off at the 180-degree point. Ground personnel at Gowen Field, on both the United Air Lines side and the National Guard side, independently observed “a glack object maneuvering in front of the same cloud formation.” The CIC interviewing officer (S/A Frank M. Brown, who would die nineteen days later in the Maury Island B-25 crash) assessed Johnson as “a man of approximately 33 to 35 years of age” with 2,800 logged flight hours including B-29 command time on Tinian Island, concluding “it is the personal opinion of the interviewer that Mr. Johnson actually saw what he states that he saw.” This document establishes Brown and Davidson operating jointly in the field on July 12, 1947, and confirms Johnson as Kenneth Arnold’s credibility validator before Johnson became a witness himself.

What the Documents Show

4AF CIC Incident Report — Credibility Assessment (Page 168)

CIC Incident Report 4AF 1208 I, dated 16 July 1947, documents the July 12, 1947 interview of David N. Johnson at the Idaho Daily Statesman offices by S/A Frank M. Brown CIC 4th AF:

“On 12 July 1947, a call was made at the newspaper office of the ‘Idaho Daily Statesman’, Boise, Idaho. The aviation editor of the paper, Mr. David N. Johnson, was interviewed in regard to how well he knew Mr. Kenneth Arnold of Boise, Idaho, and as to the credibility of any statement made by Mr. Arnold.”

The interview’s original purpose — validating Arnold’s June 24, 1947 Mt. Rainier sighting — produced an unexpected secondary result: Johnson himself had been assigned to search for flying discs and had seen one:

“Mr. Johnson stated that after Mr. Arnold reported having seen the flying disks, that the editor of the paper had assigned him, Mr. Johnson, the assignment of taking the airplane belonging to the newspaper and exhausting all efforts to prove or disprove the probability of flying disks having been seen in the northwest area.”

Brown’s assessment of Johnson’s qualifications and credibility:

“Mr. Johnson is a man of approximately 33 to 35 years of age. From all appearances he is a very reserved type of person. Mr. Johnson has logged 2800 hours of flying time in various types of airplanes up to and including multi-engine aircraft. During part of the war years, Mr. Johnson was the first pilot of a B-29 type aircraft being assigned to the Twentieth USAAF and stationed on Tinian Island, in the Pacific.”

Brown’s evaluative conclusion — filed in the case record:

“It is the personal opinion of the interviewer that Mr. Johnson actually saw what he states that he saw in the attached report. It is also the opinion of the interviewer that Mr. Johnson would have much more to lose than gain and would have to be very strongly convinced that he actually saw something before he would report such an incident and open himself for the ridicule that would accompany such a report.”

The document is signed “FRANK M. BROWN, S/A, CIC 4th AF” and filed as FBI serial 62-83894-95 ENCLOSURE.

Johnson’s Assignment Background (Page 169 — Sworn Statement Opening)

Johnson’s sworn statement, dated July 12, 1947, Boise Idaho:

“On the sixth day of July, 1947, I received from James L. Brown, general manager of the Statesman Newspapers, incorporated in Idaho as The Statesman Printing company, an assignment which was in substance: ‘Conduct an aerial search of the northwest states in an effort to see and photograph a flying disc. Conduct this patrol for so long a time as you believe reasonable, or until you see a flying disc.’”

This establishes the newspaper assignment’s scope and mandate: unlimited duration aerial patrol specifically tasked with sighting and photographing a flying disc.

The Aerial Sighting (Page 170 — Core Narrative)

Johnson’s first-person account of what he saw:

“Upon hearing this response, I turned the aircraft broadside to the object, pulled back the plexiglass covering to avoid any distortion, took my camera from the map case, and exposed about 10 seconds’ duration of eight millimeter motion picture film. During the time the camera was at eye level, I could not see the object because of minuteness of scope introduced by the optical view finder with which the camera, an f.1.9 Eastman, was equipped.”

The object’s behavior after Johnson stopped filming:

“Taking the camera away and once again centering my gaze on the object, I observed it to roll so that its edge was presented to me. It then appeared as a thin black line. It then performed a maneuver which looked as if it had begun a slow roll, or a barrel roll, which instead of being completed, was broken off at about the 180-degree point. The object rolled out of the top of the maneuver at this point, and I lost sight of it.”

Johnson’s radio contact and temporal record:

“I forgot to look at my clock to determine the exact time I saw the object. The CAA’s log of radio contacts shows my first contact to have been made at 12:17 hours. But a few seconds elapsed between the time I first saw the object, and the time I called the CAA’s station.”

Johnson’s comparison to known aircraft — what the object was not:

“I can only say it was not an airplane, and if it was at a very great distance from me, its speed was great, taking into consideration that apparent speed is reduced to the viewer if an object is a very great distance away.”

Johnson’s size comparison: “The object appeared to me, relatively, as the size of a twenty-five cent piece.” No distance or speed estimate attached.

The search efforts that followed:

“The next search, begun within half an hour after landing from the first one, consumed another two hours, but was negative. I explored thoroughly the region where I saw the object.”

Aircraft in the area at time of sighting — negative results:

“Immediately after sighting the object, I asked if there were other aircraft in the area. There was a P-51 of the 190th squadron practicing maneuvers in the vicinity of Kuna, but that was behind me. A C-82 passed over Boise, but I saw that aircraft go beneath me by some 2,000 feet. The P-51 in the vicinity of Kuna proceeded to the area where I saw the object, at my request, and conducted a search. It was negative. During the afternoon, flights of P-51s were sent out to cover the area, and some of them flew high altitude missions on oxygen. These searches were negative.”

Ground corroboration — the key institutional confirmation:

“I was subsequently informed that personnel on both the United Air Lines side of Gowen field, and on the national guard side, observed a glack object maneuvering in front of the same cloud formation, which by now had grown so that the clouds reached a probable height of 19,000 or 20,000 feet from a mean base”

Sworn Statement Closing and Notarization (Page 171)

“This statement is made voluntarily and freely, in response to the request of Mr. Brown and Captain Davidson, who called on me this morning.” /s/ David N. Johnson Subscribed and sworn to before me, a notary public, this 12th day of July, 1947. /s/ Geo. L. Flaherty, Notary public for Ada county Idaho.

Critical detail: Johnson explicitly names “Mr. Brown and Captain Davidson” as jointly present at his interview. This is the primary-source confirmation that Frank M. Brown (S/A, CIC 4th AF) and Captain William L. Davidson (who would die in the Maury Island B-25 crash on August 1, 1947) were both in Boise on July 12, 1947 — nineteen days before their deaths.

Why This Matters

1. Primary-source confirmation of Brown-Davidson joint field operation on July 12, 1947. Johnson’s sworn statement closing — “in response to the request of Mr. Brown and Captain Davidson, who called on me this morning” — establishes beyond doubt that Davidson was in Boise conducting field interviews on July 12. The Springer-Brown CIC cluster source page established this; the Johnson sworn statement provides the primary-source confirmation in Johnson’s own words.

2. First documented 8mm motion picture film of an unidentified flying object in a federal case file. Johnson’s account of pulling back the plexiglass and filming 10 seconds of 8mm motion picture film with an f.1.9 Eastman camera during the sighting is the earliest documented instance in 62-HQ-83894 of a witness capturing aerial footage of an unidentified object. The fate of this film is not confirmed in the pages read; whether it was recovered, analyzed, or filed is an open question.

3. The broken-off barrel roll is a documented aerodynamic anomaly. Johnson describes the object completing approximately half of what appeared to be a slow roll or barrel roll, then “rolling out of the top” rather than completing the maneuver. This partial-roll-recovery behavior at altitude — producing a thin-edge presentation to the observer, then disappearing — is specific and unusual. Johnson’s description is precise enough to be analyzed against known 1947 aircraft performance envelopes.

4. Gowen Field ground corroboration across two independent observation points. Personnel on the United Air Lines side and the National Guard side of Gowen Field both reported observing “a glack object maneuvering in front of the same cloud formation.” This is not a single-witness corroboration but a multi-point institutional corroboration from two different organizational components of the same airfield — aviation personnel with aircraft-identification experience, observing independently.

5. CIC Agent Frank M. Brown’s credibility assessment is his last known institutional judgment on a UAP witness before his death. Brown’s July 12, 1947 assessment of Johnson’s credibility — “the personal opinion of the interviewer that Mr. Johnson actually saw what he states that he saw” — was written nineteen days before Brown died in the Maury Island B-25 crash on August 1, 1947. Brown’s written evaluative record on Arnold (from the Arnold interview also conducted July 12) and Johnson constitutes the full surviving institutional record of his field judgment on the peak 1947 flying-disc witnesses.

6. Johnson served simultaneously as Arnold credibility validator and independent witness. The CIC’s original purpose in the July 12 interview was to assess Arnold’s credibility using Johnson’s professional relationship with Arnold. Johnson confirmed Arnold’s credibility; the interview then documented Johnson as an independent eyewitness. The institutional record preserves both functions in the same document cluster.

7. P-51 and altitude search establish the maximum performance constraints. P-51s sent out at Johnson’s request to search the area, including “high altitude missions on oxygen,” found nothing. The P-51’s service ceiling (~41,900 ft) and speed (~437 mph at altitude) define the search envelope. If the object was visible from Johnson’s altitude and outran or evaded P-51 search sorties, the implied performance characteristics are operationally significant.

8. The institutional distribution (FBI serial 62-83894-95) places this document in the Springer-Brown CIC cluster transmittal. The filing serial (62-83894-95 ENCLOSURE) confirms this document arrived at FBI headquarters as part of Lt. Col. Donald L. Springer’s August 27, 1947 transmittal of the AAF “Investigation of Flying Discs” packet. It was not a standalone case; it entered the Bureau as part of the systematic 4AF CIC investigation cluster that included Arnold’s interview, Captain E.J. Smith’s interview, and the Muroc affidavits.

Open Questions

1. What happened to the 10 seconds of 8mm film? Johnson describes filming the object with an f.1.9 Eastman camera. The CIC Incident Report references Johnson’s sworn statement as Exhibit B but does not reference film as a separate exhibit. Was the film developed? Analyzed? Recovered by CIC or Air Force Intelligence? Is it in NARA AAF holdings?

2. What did “communicator Albertson” hear on the radio? Johnson states he described the object over the radio to CAA station communicator Albertson immediately after sighting it, and that “the control tower may have a recording of the conversation.” Did CIC or FBI follow up with Albertson or the control tower? Was a recording recovered?

3. What was the second search area? Johnson conducted a second aerial search “within half an hour after landing from the first one” covering the region where he saw the object. He explored “thoroughly” but found nothing. Was this search coordinated with the P-51 sorties from Gowen Field? Were the search coordinates logged?

4. Are the Gowen Field ground-witness statements in the archive? The page 170 statement that UAL-side and National Guard-side personnel at Gowen Field observed “a glack object” is preserved in Johnson’s sworn statement. Were formal CIC interviews conducted of the Gowen Field ground witnesses? Are those statements elsewhere in Section 2 or Section 3?

5. The OCR ends mid-sentence at the Gowen Field corroboration. Page 170 breaks off at “which by now had grown so that the clouds reached a probable height of 19,000 or 20,000 feet from a mean base.” The complete sentence and any additional corroboration detail from Johnson’s statement continues on a page not captured cleanly in the OCR pass. What does the full statement say about the ground-witness observation?

6. Was Johnson’s 8mm film the “flying disc photograph” submitted to Air Force investigation? The broader 4AF CIC investigation cluster is known to include multiple photographic artifacts (Rhodes photographs, Arnold hand-drawn diagram). Johnson’s film may have been evaluated alongside or parallel to these. Was the Johnson film part of the USAF Project Sign / Project Grudge evidentiary record?

7. What is “a glack object”? The OCR renders “glack” — likely OCR-corrupted “black” or a specific descriptive term used by the Gowen Field ground witnesses. The full word affects interpretation of the independent observation.
