Post Q.o_]ltrl!,ctual Inqu_irY;
In view of the unproductive nature of the contract \vith Land- Air,
it was decided to roalco further inquiry concerninp: recent aerial object
developments in Ne\-T Uoxico .
On 9 August 19~>1 , the situation \vas discussed
\vith Lt. Col . Cox of the 17th OSI District (Kirtland AFB) . untill5l1arch
1950 the District had been diligent in foruarding copies of their reports
on aer ial object nhenomena.
Since then, no r enorts have been received
by the Geophysics Research uivision.
Colonel Gox advised that renorts
I
of stranp:e aerial nhenomena were still r eceived by the 17th OSI office,
at the rate of once or t\rice a month but little attention was beinr- given
to this matter .

I t vias l e'"""!i'
that r enr esentatives from Ll]T~ and also
from ARGOSY were interested in nublishinf articles on aerial object
ohenomena.
On 27 aUf.USt 1951, develonments concerning aerial nhenomena were
discussed at Holloman Al''B.
Lt. John Albert previously ussocicted with
the nroject had now been transferred from Holloman.
Ther efore, the
project \vas discussed ui th Haj or I:dward A. Doty -vrho had assumed resnon-
sibility.
L.ajor J.JOty, uho seemed to be thoroughly acquainted with the
situation, advised that there have been very few reports of

It was arranc;ed further that at such time uhen

Prior to departing
HAFB, the project files were r eviewed .

access to the fil es had not been r equested by any periodicals.
On 28 August 19jl, the subject \>Tas discussed informally with
•
Dr . Lincoln La Paz, who expressed disbelief in all aerial phenonena
except for the green fire- balls.
The r ed fire- ball occasionally re-
ported he believed ,.,as the visual after-effect of the green.
Their
recent oripin (1947) and peculiar trajectories did not, permit, accord-
ing to Dr. La Paz , them to be cla ssed as natut·al phenomena.
.~.he
most recent that has co~e to his attention occurred over Detroit
•
on ? July 1951.
It crossed tne city from Horthwest to Southeast
with a sharply descending trajectory which leveled out and '\·n .. s
observed by many r esidents of the city.
Dr. La Paz exryressed the
opinion -chat the fir eballs may be of our oHn rri.litary oririn, but
if not, they are a 1:1atter ot· serious co!luern.

Undoubtedly, a gooa many ot· the observations reported are attri-

ernissive clouds issuing 1rom atomic installations also has been rroposcd.
IW"ly ot· the sightinf;S are attributable to natural ohcnoruena such as
•
flight 0~ o1r ds, planets, meteors, and possib~y cloudiness.
Dr. Fred L.
\Ihi pole of Harvard , in a memorandum to t his lo.bo1·atory dated 9 J~urrt.tst 1950
relative to this problell, indicated that he had observed a tendency for
the occurrence of small detachea clouds in Hou l ~xi co Hhich might have
been mist~en for an aerial object when illuminated by the reflected
light of the moon.
Dr. .hipple investigated the possibility of a cor-
relation between the frequency of aerial pheno~ena observations and
weather conditions -- specifically cloudiness .
A rough analysis of
available \reather data, in ... icated that on the 53 nights (bet\veen
5 December 1948 and 5 March 1951) vrhen observations were r eoorted, 10
were clear, · 4 partially cloudy, 5 cor.1pletcly overcast and 14 had no
record.
The nt~ber of cloudy nights i nvolved seems unusually hirh for
New I:exico.
The weather reports vrere for the Las Cruces Ar~a only where-
as many of the observations were a considerable distance from Las Cruces .
li'urther investigation is therefore necessary to determine correlations
•
with cloudiness.
ur. Uhiople also conducted a study us to \Jhethcr tho ar:e of the
moon was related to th0 frequency of aerial phenomena observations.
The
res~ts did not indicate that the phenomena were observed largely at
fUll moon.
The stctistics show th8t of the 72 observations reported, 45
occurred when the moon was uo and 27 when it was down with many of the
observations occurring at the time of the moon ' s first quarter.
From
the statistical study, Dr. lhipple suggests that the existence of moon-
light is correlated with the ohenomena.
Dr. \lhipple 1 s frequency diagrar1
of observations vs. age of moon is included in.tbjs report.

It should be noted that Dr . Jhipnle made a cnre~ study of
meteor photogranhs tru{en in I;ew hexico on 35 nirhts when observations
Here reported.
None of the nhotographs revealed the. pr0sence of un-
usual sky phenomena .
Finally, the overall picture obtained from the year of vigilance
and inquiry does not uormit a conclusive opinion concerning the aerial
ohenomena of interest.
The comparatively hif;h incidence of tl1e ~heno-
mena since 1948 does not necessar ily indicate that the objects are
man-made. It is conceivable that the earth may be passing through a
ree;ion in space of high r.1eteoric pooulation.
Also, the sun- spot
lilrodma. in 1948 ocrhaos in some vray may be a contributing factor .

No fur vher f i scal 0xnenditure be nmde in pursuin~ the problem.
This opinion is proupted nartly by the fruitless expenditure durinp
t he past year, the uncertainty of existence of unexplainable aerial
•
objects, and by the inactive position currently tal\en by Holloman
AFB as indicated by the ''stand- by status· of the TJroj ct.
The
arrangements by HAFB for continued vigi lance by Land-Air, the
weather ststion as well as the briefing of pilot s on t he problem
in part r elieves the need for a systematic i nstrumentation program.
(2) \ i thin the next fevr months, Dr. Uhipnle will have completed
the installation of two 18-inch Schmidt cameras for meteor studies.
rrbe cameras will be stationed about ?Q mil es apart in the vicinity
of Las Cruces, New Hexico. Since these studies l.il l be sponsored
by the GRD, arrangements can be nade for examining the film for

Attn:

Wright-Patterson Air Force Base, Dayton, Ohio
"If no fire balls are observed in the next six month period, it is
reconnnended that the project be d)scontinued.
In a phenomenon as
sporad.ic as the :t'iJ.'"C balls appear to be, it is felt that at least
one year is required in order to establish '"hether their occurrence
is or is not a seasonal phenomenon.
4.
There is considerable doubt in the minds of some of the
project personnel that this is a natural phenomenon.
As long as a
-
--c:
reasonable doubt exists, 1 t is not wise to d).scontinue entirely the
observations.
Dr . Whipple s suggestion that these may be moon
reflections on small clouds cannot be discounted .
That fire balls
have been observed in the past cannot be di.scounted due to the re-
liability of' several witnesses. It may be considered significant that
fire balls have ceased abruptly as soon as a systematic \vatch vras set up.
At present it does not appear likely that the next six months of
observations will yield any more information than the first six months,
but it is felt that even oegati ve inf6rmati.on may be significant .
5. It is requested that a six month extension of the Land Air
contract be negotiated. It is also requested that the spectrographic
equipment abando~ed by Holloman Air Force Base due to lack of personnel
be turned over to Land Air for operation in the next six month period.
At the conclusion of the six month extension, an evaluation of the
observations will be accomplished by this Directorate and reconunenda-
tions as to the future conduct of this project will be forwarded to
your cOimnand. "

1. Since the date of basic correspondence this Conm~nd has been
able to initiate subject project on a limited basjs utilizing personnel
and eqttipment which have become available at Holloman Air Force Base.
For your information the investigation involves the following observa-
tional techniques:
a .
Optical tracking with Aska..'l'lia photo theodolites in order
to provide trajectory datn and photo records.
b. Optical spectra-photography using standard cameras ~nth
suitable diffraction gratings.
c .
Radio spectrum analysis through the range from 500 kc to
4000 me.
This portion of the program will be shortly started with the
Signal Corps providing equipment and personnel.

In view of this, prior RDB approval for the
project is not bt!!lieved necessary. This COimnand will take action to co-
ordinate the project through normal channels.

In order to better evaluate the results of the investigation
outlined in Paragraph 1 above, it would be very desirable to have the
activities of the 17th District OSI at Kirtland Air Force Base re-ini~iate
in making field investigations of light phenomena report s.
Such report s
would be important in the verification of any results of the project work
at Holloman. It is therefore requested that action be truten for re-ini-

In accordance with instructions contained in classified letter
from Chief of Staff, USAF to CG, AMC, s1bject
11Light Phenomena,"
11+ September 1949, the undersigned attended a conference at Los Alamos
on the subject of a phenomena observed in the northern Nevr Mexico area.
The phenomena has the appearance of a green fireball and because of the
fact that it has been observed only (as fa.r as can be determined) in the
northern new Mexico area and only since the year 1947, has caused a high
degree of apprehension among security agencies in the area.
Two reports
from the 17th District Office of Special Investigations (inclosures 1
and 2) summarizes present information on the phenomena.
In view of the
fact that the phenomena has been observed by independent and t~ained
observers there is little doubt that something was actually observed.
2 .
Inclosure 3 lists those personnel attending the conference.
3.
The first part of the conference was devoted to a sununary pre-
sentation of all collected and organized observational information re-
garding green fireballs .
The presentation wa.s made by Dr. Lincoln LaPaz
(Professor and Head of Department of Meteroritics and Mathematics: Uni-
versity of New ~exico) and Capt. Melvin E. Ncef (17th District OSI, USAF).
Dr . LaPaz has been cooperating witl1 the OSI investigators in the matter
at their request and on an unpaid basis .
Capt. Neef 1s the principal
OS! agent on the case.
Both Dr. LaPaz and Capt Neef have personally

4. The second part of the conference was a discussion by the scien-
tists present of various possible explanations and hypotheses concerning
the phenomena. Little success was had.

Subj: Report of Cotlference on "Green Fireballs''
(Project Grudge)
5. It was the conclusion of the group present at the meeting that
the present information on the phenomena was not sufficiently quantita-
tive and objective to all ow any profitable scientific consideration.
Instrt~ental observations (especially photogaphs, triangulation, and
spectroscopic ) were considered as essentj.al.
6. Dr. Joseph Kaplan, who was officially representing the Scientjfic
Advisory Board, USAF at the medting, plans to report the problem to the
next meeting of the Board (2 and 3 November)l949) with the reconnnendation
that the USP~ provide a suitable investigation of the phenomena using the
Geophysical Research Directorate, Air Force Cambridge Research Laboratorjes,
AMC as the agency ~or the project .
1. It is t he opinion of this office that the Geophysical Research
Directorate, AFCRL, is capable of performing the required investigation
(by photographic and spectroscopic means) provided that necessary funds,
personnel authorizations and equipment are provided.
Inasmuch as the
phenomena appears to be atmospheric in nature, such an assi gnment is
considered appropriate.

ABSTRACT •
Early in 1950 the Geouhysics Hesoarch Division received
a directive to investigate peculiar li ;ht nhenomena that had
been observed in the skies of the southwestern United ~tates •
•
Project '!\-Tinkle \o~as established to check into these phenomena
and their exnlanation.
The pist of the findings is essentially negative.
The period
of observation" covers a little over a yea:r.
Some unusual pheno-
mena were observed durinrt t hat period, most of then can be at-
tributed to such roan-made objects as airplanes, balloons, rockets,
etc .
Others can be attributed to natural nhenomena such as
flying birds, small clouds' tllld meteorites .
rrhere has been no in-
dication that even the somewhat strange observations often called
Green Fireballs · are anythine but natural ohenomena.
Our recommendations are in essence that there is no use in
sinking any more funds into this at the present time and that \.re
\trill keen in connection with one of our meteor studies a sharp eye
on anythin~ unusual a~ong this line.

In accordance t-:ri th instructi,ons contained in a classified letter
from Chief of Staff, USAF to CG,
Al~.1c, subject urLip,ht Phenomena· , on
14 September 191 .. 9, Lt. Col. Freder ic C.E. Oder of CR.U attended a con-
ference at los Alamos, 14 October 191,.9 on the subject of
11Green Firebal.ls'
observed in the Northern New Hexico area .
Since the phenomena had been
observed only in this area and only since 1947, it had caused considerable
concern among security agencies in the area .
It \vas the conclusion of
the scientists present at this meeting that the information available
waR not sufficiently
Instrmnental observations - photo-
graphic , triangulation, and soectroscopic were considered essential.
Dr . L. La Paz of the Denartment of Ueteori tics of Univ . of Ne¥1
J.1exico Has present at the Los Alamos meeting and subsequently \-Tas in-
vited to suh~t pr oposals for studying this ohenomena under GRD spon-
sorship.
On 2 February 1950, Dr. La Paz advised that due to diffi-
cul ties with academic arraneements , he \vas unable to undertake this
study.
Ducr·ing February 1950, the f requent reports of unexplained aerial
phenomena in the vicinity of Holloman ir J. orce Uase and Vaughn, rre'\v

These data then \-Tould be used to deoonstrate the need for initiating
a study of the ~henornena .
On 21 February 1950, an observbtion outlook

Observations with theodolight, telescope and camera '\.Jere undertaken
between the hours of sunrise ru1d sunset.
On 5 l1arch 1950 e. conference was held at 1Tigbt-Patterson Air

Some nhotoeraphic activity occurred on 27 Anril and 24 Hay, but
sil!.lul taneous sightinrs by both cameras were not made , so that no
information was gained.
On 30 A rust 1950 ·' during: a Bell aircraft

Air Force Base by several individuals ; hovrever, neither L-:nd- Air
nor l r oject ner sonncl wer e notified and, therefor e , no results wer e
acquired .
On 31 August 1950, the ohenore.ena \·rer e agai n observed

On 11 September, arranp;ements \vere r:tade by Holloman

facilities for the electromagnetic f r equency me..asurmaonts that were
to be )rovided by the Signal Coros ~ngineerine Laboratories were not
utili zed due to the fact that the frequency of occurrence of these
phenomena. did not justify the
50, 000 a year transfer of funds to the
Si gnal Corps which wo\ud be required to carry out such a monitoring
facili ty.
Ho ,o~ev er, the phenomena activity over Holloman AF13 150 miles
south of Vauglm, !. l!exico during the l atter part of 'ugust 1950 was
consider ed sufficiently significant so that the contract with Land-Air
