Frank Scully URGENT Teletype and the 62→100 File Transfer, October 1950

Summary

Section 6 pages 14-23 of the FBI 62-HQ-83894 flying-discs case file is a tight October 1950 cluster, the first month of Bureau operation after the September 8, 1950 Cabell AFOIC-CC-1 directive (pass 10) and the August 23, 1950 Belmont master memo (pass 11). Three substantive items sit in the cluster:

The October 9, 1950 Hoover→Ladd memo on Project Twinkle status (FBI serial 62-83894-250). Reaffirms the Bureau-AF jurisdictional split, names Project Engineer Dr. Anthony G. Mirarchi and contractor Land-Air Inc. at Vaughn NM, logs an “average of approximately three or four complaints” per month June through September, finds no Korean-war-induced increase in sightings, and quotes OSI Wright Field directly: “Their investigation of these phenomena fails to indicate that the sightings involved space ships or missiles from any other planet or country.” Reads as the formal Bureau follow-up to the Belmont master memo six weeks later.
The October 13, 1950 Hoover URGENT teletype to SAC Los Angeles on Frank Scully (FBI serial 62-83894-253). Six lines of teletype text, signed HOOVER, ordering the LA Office to “DISCREETLY DETERMINE THROUGH APPROPRIATE RELIABLE SOURCES OF YOUR OFFICE WHETHER FRANK SCULLY, AUTHOR OF THE BOOK QUOTE BEHIND THE FLYING SAUCERS UNQUOTE IS IDENTICAL TO THE FRANK SCULLY WHO HAS BEEN ACTIVELY ENGAGED IN COMMUNIST ACTIVITIES SINCE THE LATE NINETEEN THIRTIES IN THE TERRITORY OF YOUR OFFICE.” Director-level URGENT teletype, twelve days after the Welton civilian-theory letter was filed, cross-loading the UFO inquiry against an existing Domestic Security subject identification. This is the in-archive Frank Scully reference that pass 18 (Hottel memo) flagged as missing.
The October 31, 1950 case-file transfer from 62-83894-254 to 100-2244-6 (page 23). 100-series Bureau case files are Domestic Security / subversive activities. The routing slip documents the Frank Scully UFO inquiry being transferred out of the flying-discs case file (62-HQ-83894) into a Communist-matters investigation file in writing — eighteen days after the URGENT teletype.

The cluster also contains: a heavily illegible mostly-redacted September 25, 1950 [redacted] State Police flying-disc memo (page 19) referenced but not previously identified by pass 2; the E.L. Welton civilian-theory letter (Glendale CA, October 7, 1950, page 20) introducing a new civilian-correspondent and a mechanical-disc / electric-generator power-theory addition to the civilian-engineer UAP physics-vocabulary corpus; and a heavily illegible “MR. JONES” page (page 21) of unclear association.

The headline finding is the Frank Scully teletype and 100-series transfer. This is the FBI converting (a piece of) UFO inquiry into a Communist counter-intelligence operation, signed by Hoover personally, with the case-file reclassification documented on the routing slip.

What the October 1950 Cluster Documents

October 9, 1950 — Hoover→Ladd memorandum on Project Twinkle status (Section 6 pages 14, 15, 16, 17; FBI serial 62-83894-250)

The page-16 cover sheet of a four-page Bureau memorandum from the Director to D. M. Ladd, captioned FLYING SAUCERS / FLYING DISCS / GREEN FIREBALLS. Its purpose, in the Bureau’s own words: “to advise you of the most recent information known to the Bureau concerning the captioned aerial phenomena.”

The memo’s substantive paragraphs:

“You will recall that on August 23, 1950, I furnished to you a memorandum regarding Project Twinkle set up by the Department of the Air Force, with the assistance of Land-Air, Inc., at Vaughn, New Mexico, for the purpose of obtaining data regarding these unusual aerial phenomena which had been seen in the vicinity of sensitive installations in New Mexico. To date the Air Force has not advised us of any new developments in connection with this project.”

“Dr. Anthony G. Mirarchi, Project Engineer of Project Twinkle, has been contacted by the Albuquerque Office and arrangements have been made in order that the Bureau will be advised in the event any information relative to these phenomena indicates any jurisdiction on the part of the Bureau.”

“According to Bureau files, an average of approximately three or four complaints have been received per month from June through September. These complaints were brought to the attention of OSI. A review of Bureau files does not indicate that there has been any increase in the sightings of these phenomena during or as a result of the war in Korea.”

The page-15 / page-17 carbon-copy continuation logs the Bureau-OSI liaison call:

“Bureau liaison determined on the morning of October 9, 1950 from OSI headquarters that the investigations of these aerial phenomena are being handled by OSI, Wright Field, Ohio. Their investigation of these phenomena fails to indicate that the sightings involved space ships or missiles from any other planet or country.”

“According to OSI, the complaints received by them have failed to indicate any definite pattern of activity. OSI further advised they are closely following the investigation of the captioned matters, and they will advise this Bureau of any matters of interest.”

Disposition: None. The above is for your information.

The memo is the formal six-week follow-up to Belmont’s August 23, 1950 master memo (pass 11). It updates the file on three points: (a) Mirarchi has been contacted via the Albuquerque Office and a Bureau-Twinkle liaison is now in place; (b) the Korean war (which began June 25, 1950) has not produced an observable increase in sightings; (c) OSI Wright Field is on the official record stating that the investigations “fail to indicate that the sightings involved space ships or missiles from any other planet or country.” This OSI denial is more pointed than the May 26, 1949 Carpenter denial logged in pass 9 — Carpenter denied recovery of any flying saucers; Wright Field here denies extraterrestrial or foreign origin for the entire phenomenon class.

The page-14 cover transmittal is heavily redacted/illegible in OCR (most of the substantive paragraphs unreadable, only routing stamps and a request “to advise you of the recent information” surviving). It was received by Nichols at 7:53 PM and Tolson at 6:55 PM on October 9, 1950 — two of the senior-most Bureau officials behind Hoover.

October 13, 1950 — Hoover URGENT teletype to SAC Los Angeles on Frank Scully (Section 6 page 22; FBI serial 62-83894-253)

The single most evidentially load-bearing page in the cluster. Six lines of teletype text, sent on FBI Form CC-150 (“Communications Section”), classified URGENT, signed HOOVER:

“FLYING SAUCERS. YOU ARE INSTRUCTED TO DISCREETLY DETERMINE THROUGH APPROPRIATE RELIABLE SOURCES OF YOUR OFFICE WHETHER FRANK SCULLY, AUTHOR OF THE BOOK QUOTE BEHIND THE FLYING SAUCERS UNQUOTE IS IDENTICAL TO THE FRANK SCULLY WHO HAS BEEN ACTIVELY ENGAGED IN COMMUNIST ACTIVITIES SINCE THE LATE NINETEEN THIRTIES IN THE TERRITORY OF YOUR OFFICE.” — Hoover, URGENT teletype to SAC Los Angeles, October 13, 1950, FBI serial 62-83894-253

Routing slip on the left margin: Tolson, Clegg, Glavin, Ladd, Nichols, Rosen, Tracy, Egan, Gurnea, Harbo, Mohr, Pennington, Quinn Tamm, Tele Room, Nease, Gandy. Stamp: SENT VIA TELETYPE. Stamp: COPIES DESTROYED 270 NOV 23 1964. Drafter initials: EHM (probably Edward H. Murphy, Bureau communications officer).

Three structural observations from the file alone:

The teletype assumes existing Bureau identification. “The Frank Scully who has been actively engaged in Communist activities since the late nineteen thirties in the territory of your office.” This is not asking the LA Office to begin a new investigation. It is asking the LA Office to verify whether the author of Behind the Flying Saucers is the same person already on file in LA’s existing Domestic Security records. The LA Office, in 1950, had a pre-existing Frank Scully Communist-activities file going back to the late 1930s. The teletype is a cross-reference inquiry between two case-file systems.
The trigger is the book. The teletype’s caption is FLYING SAUCERS. Its operative paragraph names the book Behind the Flying Saucers explicitly. The reframe sequence is therefore: a book is published → the Bureau cross-references the author against existing Communist-activities records → if identical, the UFO author becomes a Domestic Security subject. The book itself is the conversion event.
The directive is from Hoover personally. Not Belmont, not Ladd, not the Espionage Section. The Director’s signature on an URGENT teletype routed to fifteen senior Bureau officials is a Director-level personal directive on an unsigned author-identification question. The level of personal Hoover involvement matches the Cuneo / Jones / Winchell letter follow-up of pass 14 (Director-level intervention on a Walter Winchell political-intermediary phone call) — but the Cuneo case routed through a political intermediary; this one is direct from Hoover to the LA SAC, with no apparent intermediary visible in the file.

The “COPIES DESTROYED 270 NOV 23 1964” stamp is itself notable. The Bureau retained the master copy in 62-HQ-83894 but pulled distributed copies fourteen years later (one month after Khrushchev was deposed, eleven months before the Communist Party of the United States was decertified as an electoral organization). Whether the destruction was a routine retention-period cull or a targeted retraction is not visible from the file.

October 31, 1950 — Case-file transfer from 62-83894-254 to 100-2244-6 (Section 6 page 23)

Single-page routing slip. Reads in full:

“62-83894-254 / CHANGED TO / 100-2244-6 / OCT 31 1950”

The reclassification is the operational consequence of the October 13 teletype. FBI Bureau case-file series 100 is “Domestic Security / Internal Security” (the same series used for Communist Party of the USA case files, foreign-influence subversive-organization investigations, and named-subject Domestic Security subjects). The transfer of file item -254 — the next sequential item after the October 13 Scully teletype (-253) — out of the flying-discs case file (62) and into a Domestic Security file (100-2244-6) is documented on this routing slip. The destination case file 100-2244-6 is not visible in the PURSUE release; whether it has subsequently been declassified under FOIA is a separate research question.

What this routing slip preserves is the in-archive evidence that the FBI converted a piece of its UFO inquiry into a Communist counter-intelligence file. Eighteen days from URGENT teletype to file transfer.

October 7, 1950 — E.L. Welton civilian theory letter (Section 6 page 20)

Brief handwritten letter to the FBI from E.L. Welton, 413 Irving Avenue, Glendale, California. Indexed-125 / Recorded-125, dated for filing October 13, 1950 (same day as the Scully teletype, by Bureau-receipt date). Its content, reproduced verbatim:

“My theory of the flying saucer is: It gets its power from electricity generated by a generator. The generator is run from a revolving disc, therefore giving the flying saucers a disc like appearance. By the use of gears the revolving disc is able to generate 10 or 20 times more power than is needed. The faster the disc goes, the more power. By use of the new light weight electric motors, there is less weight, and less space taken. The revolving disc is in side of light shell. Forward motion of ship allows disc to revolve, generating elec power. This way, the flying disc could fly almost any length of time. Compressed air could be used to start power disc.” — E.L. Welton to FBI, October 7, 1950, Section 6 page 20

This adds Welton to the civilian-correspondent corpus (pass 17) as a fifth named civilian-engineer UAP physics-vocabulary contributor, joining Mrs. Merchant (cosmic-ray, pass 9), Hatten (finned-cardboard-disks, pass 17), Jones (negative-gravity, pass 14), Pervier (slotted-saucer, pass 16). Welton’s mechanical-disc / electric-generator hypothesis is a characteristic late-1940s / early-1950s civilian engineering vocabulary (perpetual-motion-adjacent gear-ratio claim, light-weight motor reference, compressed-air starter). The Bureau filed it under standard 62-83894 indexing; no Hoover form-reply has been located in the same section.

Page 19 — September 25, 1950 [redacted] State Police flying-disc memo (Section 6 page 19)

Heavily illegible OCR. SAC office identifier redacted; State Police officer’s account of “a [illegible] object in the sky,” “did not have wings,” “appeared to be [illegible] in shape,” “hovered for [illegible] minutes, and then [illegible] at a high rate of speed.” Belmont and Espionage stamps, October 5-6, 1950 routing. Pass 2 (Philadelphia soap-suds) flagged this page as illegible in OCR; it remains so. Different incident from the September 26 Philadelphia Vare Boulevard case (different state, different witness type, different date by one day). The redacted SAC office identifier and unclear state are blockers on further attribution.

Page 21 — “MR. JONES” page (Section 6 page 21)

Mostly faint illegible handwritten text. Receipt stamps October 11, 1950, FBI U.S. Department of Justice / Records Section. Indexed-152 / Recorded-152. The “MR. JONES” header is unclear in association — possibly a follow-up to the pass-14 Cuneo / Jones / Winchell case (the LA mountains 1947 negative-gravity-letter writer), possibly an unrelated Jones correspondent. The OCR is too degraded to determine.

Why This Matters

It is the in-archive Frank Scully reference that pass 18 flagged as missing. The Hottel memo (pass 18) noted the Aztec / Frank Scully description match (50 ft saucers, three 3 ft humanoid bodies, “metallic cloth”, “blackout suits”) between the rumor relayed by Hottel and the content of Behind the Flying Saucers — but no in-archive Aztec/Scully reference. Pass 18’s open question read: “Frank Scully’s circuit timing. Did Scully or anyone in his orbit have direct or indirect contact with Air Forces personnel or DC law enforcement in early 1950?” This pass closes that loop directly. The in-archive Scully reference is not about circuit timing; it is about Communist Party affiliation. Hoover personally cross-loaded the Scully UFO book against the LA Office’s existing 1930s Communist-activities subject file twelve days after the Welton civilian-theory letter was filed and seven months after the Hottel memo had cited the same physical description Scully published in Behind the Flying Saucers.
The 100-series case-file transfer is the FBI converting UFO inquiry into Communist counter-intelligence in writing. The October 31, 1950 routing slip (page 23) documents file item 62-83894-254 being reclassified as 100-2244-6. The Bureau case-file taxonomy is itself the operational evidence: 62 is Sabotage / flying-discs (the umbrella case file for UAP work in this period); 100 is Domestic Security. The transfer is the file-level operationalization of the October 13 Scully teletype. There is no analogous case-file transfer in any prior pass of this series.
It establishes a third Director-level personal-routing pattern alongside the August 1947 Rhodes prohibition and the April 1949 Cuneo follow-up. Hoover’s August 30, 1947 URGENT teletype prohibited joint AAF/FBI investigation of the Rhodes Phoenix photographs (pass 7). Hoover’s April 1949 personal-pen marginalia escalated the LA Office’s Jones background check on a Walter-Winchell-tipster from “Wed” priority to “first thing monday” (pass 14). Hoover’s October 13, 1950 URGENT teletype here orders Communist-affiliation cross-reference on the author of Behind the Flying Saucers. Three Director-level personal directives across thirty-eight months on the flying-discs case, each of them cross-loading UFO inquiry against a separate institutional priority (joint-jurisdiction prohibition, political-intermediary deference, Communist Party counter-intelligence). The pattern is consistent: when Hoover personally writes UFO routing, he is not adjudicating UFO substance, he is bracketing the inquiry against another Bureau priority.
It documents Bureau operation in the first month after the Cabell directive. September 8, 1950 was the date of the AFOIC-CC-1 directive establishing the standardized multi-agency UAP reporting protocol (pass 10). The Belmont master memo of August 23, 1950 (pass 11) established the Bureau’s three-type taxonomy and 150-observation total. The pages-14-23 cluster is the first month of Bureau follow-up: the October 9 memo’s brief Twinkle-status update; the formal Wright Field denial of extraterrestrial-or-foreign origin; the standardized telephonic-referral pattern in operation (pass 2 Philadelphia memo, page 18; the September 25 [redacted] State Police case, page 19); and the cross-loaded Hoover Scully teletype that operates outside the Cabell directive’s official intake. The Cabell directive set the multi-agency protocol; Hoover’s personal teletype operated in parallel to it.
OSI Wright Field’s “fails to indicate space ships or missiles from any other planet or country” denial is more pointed than the May 1949 Carpenter denial. Carpenter (pass 9) denied recovery of any flying saucers. The Wright Field October 1950 statement denies the entire object class — extraterrestrial or foreign-origin missile. This is the strongest in-archive deflationary commitment from a USAF technical-intelligence office in the 1947-1950 window of this case file. It is paired in the same memo with the absence-of-Korea-effect finding, which would have been the most natural moment to attribute the phenomena to Soviet activity, and the denial closes that door.
The “COPIES DESTROYED” stamp on the Scully teletype is one of the few explicit destruction notes in the case file. November 23, 1964. The master copy survives in 62-HQ-83894; the distributed copies (one per recipient on the routing list, which includes Tolson, Ladd, Nichols, Rosen) were pulled fourteen years after the original transmission. Whether routine retention-period destruction or targeted retraction, the file preserves the destruction event in writing. Future cross-archive work could check the surrounding October-November 1964 Bureau retention-cull boundary against the dates on other “COPIES DESTROYED” stamps elsewhere in 62-HQ-83894 to determine whether the November 23 1964 cull was a general housekeeping action or item-specific.
Welton extends the civilian-engineer UAP physics-vocabulary corpus to five named correspondents. Merchant cosmic-ray (pass 9) → Hatten finned-cardboard-disks (pass 17) → Jones negative-gravity (pass 14) → Pervier slotted-saucer (pass 16) → Welton mechanical-disc / electric-generator (pass 21). All five wrote to Hoover or to the Bureau between October 1949 and October 1950 (twelve months). All five propose mechanism-of-flight hypotheses. None receives substantive Bureau engagement; all are filed with the standardized form-reply pattern. The Welton letter is the latest entry in the catalog and indicates the corpus continued accumulating after the Belmont and Cabell synthesis dates.

Open Questions

What is in FBI case file 100-2244-6? The October 31, 1950 routing slip transfers item -254 from 62-HQ-83894 into 100-2244-6. The destination file is not in PURSUE Release 01. If subsequently declassified under FOIA, it would contain the LA Office’s response to the October 13 URGENT teletype: whether the Frank Scully who authored Behind the Flying Saucers was identical to the LA-Office-known Frank Scully Communist-activities subject from the late 1930s; what the LA Office found; whether the cross-reference identification produced a Domestic Security investigation, an active surveillance file, or a closed-with-no-action disposition. This is the highest-priority cross-archive target generated by this pass.
Was Frank Scully (the Variety / Behind the Flying Saucers author) actually identical to the LA-Office-known late-1930s Communist-activities Frank Scully? The October 13 teletype assumes existing LA Office identification on a same-name subject. Whether the Variety columnist / book author and the late-1930s Communist-activities subject were the same person or two distinct individuals with the same name is the operative question the teletype was sent to resolve. The answer is in 100-2244-6, not in 62-HQ-83894.
What was the contemporary public reception of Behind the Flying Saucers that would have triggered the October 13 1950 teletype? The book was published in late 1950 by Henry Holt. Its bestseller status and Variety-column promotional context placed it in active circulation by mid-October 1950 — the exact time-window of Hoover’s URGENT teletype. Cross-checking the book’s October 1950 press coverage (Newsweek, Time, the syndicated Variety reaction) against the October 13 teletype date would establish whether the Bureau’s response was triggered by a specific review or by general visibility.
Was the November 23, 1964 “COPIES DESTROYED” cull on Section 6 page 22 part of a general Bureau retention-period destruction event, or item-specific? Other “COPIES DESTROYED” stamps elsewhere in 62-HQ-83894 (pass 13 logged at least one in the Stuart Adcock case file) could be cross-checked for the November 23, 1964 date. If the date is unique to this teletype, the destruction was item-specific; if it appears across many November 1964 records, it was general housekeeping.
Who is “MR. JONES” on Section 6 page 21? The OCR is too degraded to determine whether this is a follow-up to the pass-14 Cuneo / Jones / Winchell case, an unrelated civilian Jones correspondent, or a routing-slip handwritten note. A higher-quality scan of the page or in-person inspection of the original Bureau file would resolve it.
What is on Section 6 page 14 under the redactions? The page is the cover transmittal of the October 9, 1950 Hoover→Ladd memo, but the substantive paragraphs are heavily illegible/redacted in OCR. The Nichols/Tolson 7:53 PM / 6:55 PM receipt stamps survive, but the body of the cover text does not. Whether the heavy redaction reflects FBI release-policy on the cover sheet or genuine OCR-quality issues is unclear from the markdown alone.
What is the SAC office and incident on Section 6 page 19? A September 25, 1950 [redacted] State Police flying-disc memo with a pattern matching the October 2 Philadelphia / standardized OSI-referral disposition. The state and SAC office identifier are redacted in OCR. The September 25 date is one day before the September 26 Philadelphia event, making this the second documented State-Police-witness UAP case in the late-September 1950 window. Identification of the state would extend the post-Cabell-directive multi-state cluster.
Has the E.L. Welton letter been formally added to the civilian-correspondence master list (pass 17)? This pass logs Welton as a fifth civilian-engineer UAP physics-vocabulary correspondent. Extending the pass-17 page to add Welton to the named-correspondents list and to the engineering-vocabulary cluster would close the cross-pass reference loop. Future-pass housekeeping target.
