Research/info gathering UFO History: Project Twinkle and Dr. Kaplan vs. Dr. LaPaz
I have been recently conducting research into the origins of the modern UFO subject. A large part of that has been reading through these various lengthy historical declassified reports. Among them is a very interesting one, Project Twinkle.
As I read the documents I write down quotes that I find interesting or significant. For my citations I use APA format and directly link to every source document cited.
Some of the reports are hundreds of pages long. Project Twinkle is relatively manageable at 34 PDF pages and I ended up with four pages of quotes after going through it.
I wrote up this post in part to share what I found, and also to clarify my own understanding of what I've read by working with it after the fact. I will aim to continue this effort as I make progress with an ongoing series here on r/UFOscience that I will continue to title as "UFO History" moving forward.

Project Twinkle was the first known attempt to study UFOs as a real physical phenomenon in Earth's atmosphere using empirical methods via an instrumented long-term scientific field study.
This project was managed by the USAF’s Cambridge Research Laboratory, and it was established to investigate a series of UFO reports witnessed by numerous observers in Nevada and New Mexico, particularly over Los Alamos (AARO, 2024, p. 15).
The original Project Twinkle methodology and objectives were strikingly similar to the UFO field studies undertaken by UFO researchers in the public domain decades later, first by Dr. Harley Rutledge in Project Identification in the 1970s and then by Erling Strand & co. in Hessdalen starting into the 1980s and continuing to the present:
“...the investigation involves the following observational techniques: a. Optical tracking with Askania photo theodolites in order to provide trajectory data and photo records. B. Optical spectro-photography using standard cameras with suitable diffraction gratings. C. Radio spectrum analysis…” (Project Twinkle, 1950, PDF p. 15).
Before I get into LaPaz vs. Kaplan. A strange thing I found related to an explicit discrepancy between what the official 2024 AARO report states versus what the original Project Twinkle Final Report states as to the period of operation of Project Twinkle.
Though the 2024 AARO Historical Record Report Volume 1 states that it ran from approximately Summer 1949 to Summer 1950 (p. 15), the contents of the declassified Project Twinkle report record a slightly different timeline.
The Project Twinkle Final Report is dated as 27 November 1951 (PDF p. 29). Within the final report the contractual period is given as 1st of April 1950 to 15th of September 1950 (PDF p. 33). This is obviously not consistent with the dates provided in the 2024 AARO report.
Additionally, in a letter contained in the Project Twinkle declassified records dated 15 September 1950 (PDF p. 14), it says:
"If no fireballs are observed in the next six month period, it is recommended that the project be discontinued. In a phenomenon as sporadic as the fireballs appear to be, it is felt that at least one year is required in order to establish whether their occurrence is or is not a seasonal phenomenon” (PDF p. 14).
The Final Report states that Project Twinkle was in fact extended for this additional six months as requested, past its original six month contract period ending 15 September 1950, the extension running 1 October 1950 to 31 March 1951 (PDF p. 34).
It was surprising to find that the author(s) of the 2024 AARO Historical Report failed to accurately report the project dates provided within the Project Twinkle Final Report. No cause can be inferred without conjecture.
Anyway, on to Kaplan and LaPaz.
Dr. LaPaz is a fascinating character in the early UFO history.
“Director of the Institute of Meteoritics and Head of the Department of Mathematics and Astronomy at the University of New Mexico. He was Research Mathematician at the New Mexico Proving Grounds under an OSRD appointment in 1943 and 1944, and Technical Director of the Analysis Section, Headquarters, Second Air Force, 1944-45. Dr. LaPaz has served on a voluntary basis as consultant for strictly in connection with the green fireball investigations” (Declassified Memo, 1950, p. 21).
He was one of the top meteor experts in the world at the time and secretly worked for the US government in early UFO investigations related to UFO sightings over Los Alamos, including via Project Twinkle.
Prior to Project Twinkle, LaPaz was also involved in Project Grudge, successor to the USAF's UFO investigation Project Sign. The final Grudge report alludes to the creation of Project Twinkle:
“Since 5 December 1948, a series of recurring phenomena described as "green fireballs" have been reported in the general vicinity of Albuquerque, New Mexico. Dr. Lincoln La Paz, noted meteoritic expert, has been directly, though unofficially, associated with the investigation of these sightings and has himself observed the phenomena. Dr. Lа Paz states he is convinced the green fireballs are not ordinary meteors. This group of incidents has little or nothing in common with other incidents on file with Project "Grudge", therefore, these incidents are not considered in this report. The Scientific Advisory Committee was asked to investigate this matter and had advised that an independent investigation be conducted in the field of atmospheric research” (Grudge, 1949, p. 7).
LaPaz felt that UFOs were unlikely to be natural phenomena:
"Their recent origin (1947) and peculiar trajectories did not permit, according to Dr. La Paz, them to be classified as natural phenomena” (Project Twinkle, 1950, PDF p. 6).
That did not mean LaPaz subscribed to the extraterrestrial hypothesis. Instead, he felt strongly that the UFOs were Soviet in origin:
“a possible interpretation of the concentration of sightings referred to in paragraph 4 is that the green fireballs result from guided missiles launched from bases in the Urals” (Declassified Memo, 1950, p. 65).
and as mentioned by Ruppelt,
“Kaplan mentioned Dr. La Paz and his opinion that the green fireballs might be man-made” (Ruppelt, 1956, p. 78, para. 6).
Also involved in a similar capacity was Dr. Kaplan. According to the first Blue Book chief, Ruppelt:
"Dr. Joseph Kaplan, a world-renowned authority on the physics of the upper atmosphere" (Ruppelt, 1956, p. 51, para. 1).
According to the Project Twinkle Final Report, no firm conclusions could be drawn from the study because ultimately the personnel were pulled off the equipment for deployment to the Korean war which started shortly after the project's initiation in early 1950:
“...the overall picture obtained from the year of vigilance and inquiry does not permit a conclusive opinion concerning the aerial phenomena of interest” (PDF p. 8, para. 1).
“...nothing of a security nature has been discovered” (Project Twinkle, 1950, p. 12).
“Recommendations: Since the findings to date cannot be considered conclusive, it appears that the following recommendations would be pertinent: (1) No further expenditure be made in pursuing the problem. This opinion is prompted partly by the fruitless expenditure during the past year, the uncertainty of existence of unexplainable aerial objects…” (Project Twinkle, 1950, p. 8-9).
Regardless, both LaPaz and Kaplan's opinions were put into the final Project Twinkle report despite their opinions differing as previously mentioned. Even though the final report included both perspectives, it seems that Kaplan's opinion that UFOs were natural phenomena was the one more broadly accepted by the final report authors:
“...Since the establishment of the special project… (Project Grudge), to investigate and analyze reports on so-called ‘Flying saucers’ and unidentified aerial phenomena, many reports have been received through intelligence channels from persons who have observed what they considered to be unusual light phenomena… Analysis by various specialists has indicated that many of the incidents involving light phenomena were undoubtedly observations of natural phenomena… Dr. Kaplan has concluded that the ‘green fireballs’ are natural phenomena” (USAF: Project Twinkle, 1950, p. 21).
No assessment can be made as to the correctness of the conclusions contained in the report. As we all know classified internal reports can be wrong (see Iraq WMD situation estimates).
What can be established is that the historical reports like this were classified prior to the existence of FOIA laws and so were written without any expectation of them ever seeing the light of day, rather than being part of an externally-oriented disinformation campaign. They were internal briefings that were intended to contain their best estimates of what was actually occurring and were used to inform decision making on the subject.
The LaPaz vs. Kaplan clash of UFOs as technology vs. natural phenomena was in an evolved form by this point in 1950-51. Significantly, rather than being dismissed out of hand, the extraterrestrial hypothesis had been seriously debated and thoroughly contemplated up to this point within previous classified reports, such as in the final report produced by Project Sign in 1949. I will aim to provide a summary of those debates in a future write-up.
The early history of the official secret government investigations into UFOs shows that there was quite a bit of disagreement among the scientists involved in the studies, but perhaps the most interesting aspect is that they were all in agreement that something genuinely novel with extraordinary unexplained features was actually being observed.
