1. Reference is made to secret letter. your headquarters. dated
1 April 1949• Subjects Security Inspection.
2. a. Guard Orders have been amended directing that the elec­
tric gate be closed between 1700 hours until 0700 hours the following
day.
b. Looks have repl~ced the bolts in all inspection access
gates in the outer fence.
c. Inspection ports on both bridges are now pr ovided with
locks.
d. The final draft of our alert plan has been reviewed and
will be published and distributed for study to operating personnel.
It is desired to point out that the alert plan is incomplete. !.
stockpile custodian has not been assigned here; his part in the alert
plan has been outlined only.
Furthermore, since the 11th Airborne
'
Division is not in place yet, only temporary arrangements for defense
have been made. Final form of the overall alert plan will be sub­
mitted to your headquarters for approval as soon as conditions will
allow. ·1n the interim period. it is felt that the temporary alert
plan we have prepared is adequate. A copy of this pl an will be dis­
patched to your headquarters in the near future.
e. !11 jeep radios are now installed in jeeps.
r. ~lthough not entirely satisfactory. radio oom.munioation
with the Camp Campbell Military Police has been in effect for some­
time and was in effect at the time of the Security inspection. .Pe~­
manent arrangements for radio communication with Camp Campbell Military
Police are del ayed panding the arrival of radio frequency crystals
that fit the Milit ary Police net frequency.

g. Pressure has been exerted to get the Post 'Ehgineers to
keep the dra.inage system. clear and to take measures to check the ero­
sion. These efforts will be continued but lit tle progress on erosion
control can be expected until the rains diminish.
Ditches have been
filled, dirt moved and replaced, native gras ses planted, but the rains
return too soon and much of the effort invested is therefore wasted.
Plans a.re prepared f or an interim erosin control effort, and a stud;y
is being ma.de to estinate the cost of resloping the cuts in order
that the rainfall mq be drained with less damaging results. Initial
estimates run in the neighborhood of twenty thousand dollars (t20,ooo.oo).
3. With the exception of halting the erosixm, all deficiencies
listed in the security inspection report have been cleared away. It
is therefore requested that the monthly report of action taken re­
quired by cited letter be discontinued.

Doar l.1ncoln:
I a::n lnclos1ng two copies or the report you asked tor, fllld hope
that they oerve their purpose.
\'lo Jiave mado a preliminary ez:eminntion ot tm elghtaon collact1ona
token at nine locatione on my,l!onde.:,• 'l'uesday trip.
!lbere was a large
number of coppor-boar1ng pe.rtiolee on one eolleotion (ll-104L) taken on
Higm1ay 84, seventeen ·mles north ot E1gl:may 66 1 and aoa.ttered occas•
i onal particles throJJ.ghout the series.
The collection teken at tho
Blt"lle location imcodiately' following R- l04L eho'\YD practically no copper.
A 1orge l)art of the n - 104L is of a granular mnterial untamiliar to us, and
, the copper indioat1ona ori,:.inate principal ly 1n l'lhat are e.pparontl'1
aggregations of finely (ona .. meron) granular material of overall sizes
in tho neighborhood of thirty microns.
Some cop_per _part! ,lea, hor.­
ever, appear to be solid nnd o,Paque.
The passage of t-, automobiles while
this oollection uas being made is a complicating fe.ctor.
It is hard
to aee how they mieht he.Ta been a eourco ot coppor, ho,raver, unlean it
nao a question of stirring up aoI!lo :trom dust on the -pavement.
We intend to do some :1"urther chemi.eal work Tii th theee colloctions,
but I doubt if muoh nen relevant information 11111 be obtained.
Hy tentative conclusion is that no ~idcspread significant dispersion
or copper-bea't'ine; particles ,vas present in tbe atmoaphere in the rc"ion
covere.:1 at the timo the eollcct1ons wore made. l,o det1nita statel':lcnt

A'3SOOIA'l'ED fJI'l'iJ THE FIREBALL OF JULY 241 1949
By
• n. Oroztor
and
Ben x. Seely
HBTHOD
A 'fireball was raportad to have pasaod ovor the general noighborhood of
Socorro, Uew Uexi.00 1 at 8:26 p.m. 1 J'uly 241 1949.
Impaotment equipment, develop9d
in conneation 1a th the sarosol research proJect ot the New Mex1 co School of !lines,
was available, and it was decided to make systematic collections ot airborne me.ter­
- iel. in the hope ot obta1nill8 material that could be associated .-1th the t1reball.
For the present report it is suftio1ent to state that the equipnant processed air
at the rate ot about J4 11tera per minute, the particles being separated f'rom the
air by -impactment against en adhesi'f9-coate~ plate in an air jet.
Appro:d!natel.y
ninety per cent of airborne particlee with dianeters greater than one micron are
collected.
Tho adheeive used. on the collecting plates (mcroscope slides) waa a glycerin­
gelatin tlixture w1th an a.dd1tion or rubeanic aeid (dithiooxamide. )
'l'lus reagent
was used to enable identifioation of copper or copper compounds; it also enables
identification of nickel and cobalt.
After ?C:lking the eollaotions, the slides were
covered with e. Saran til::l, after which thoy were exposed to strong aomonia vapor
for r1:tteon Jninutes to effect partial ao lution or any copp_er or copper oxide parti­
el.Gs.
R ESULT S
'?he first oolleotion was made at 10:00 a . m., .ruly 25, about thirteen and one­
he.lf houra after the fireball was seen.
The air wan te.lcen about twelve teet above
ground lovel, on t he Ol!!'.IJ>UO ar the School ot Uines.
Tho first run was i'or three min-
,
utes , ll['COosaing cbout 102 liters of air.
Sevoro.l large particles wero :round in it
that gave J)ositiva co pe.r teats. In at least ono or these the copper reaction was
aeen petore the cn::mx>ni c tro~ont, indicating the presence 9f at least a trace of a
aoluble copper co~pound.
The sizes of particles aoon in tho first oollections ranged
up to over one hundred microns in the largest dimension: the largest particles gave
tho impression o~ bein.g f'r8gl:lents or a so:i:ievm.at f'ibrous material, llith the smaller

The counts are exhibited in tbreo size claeRiflcations, end attention is
directed to tlie :ta.at that particles in the smallest s!ze croup (l to l5 microns)
e::-e practically absent trom the early oollectlona, mil& in the later collectiow,,
particles 1n the largest (.30 mioron.o) 8Ii.d middle (15 to 30 microna} groups have
become cp;ite esoarce.
At the same tine, the counto have beccte quite large in tile
:.s:ncllest aizo group.
SIONIFICA~CE
OF
RESULTS
If 1 t were possible to SflY that particles giving a copper test are generally
very rare in eollectione near groimd leTel in this locaJ.lty, the above facts t'.Ould
bo highly s!gni1'1cant. It l1appens , however, that collections have been :-:,ode at
Socorro over only- a short period, and not .muoh e.tten1i1on has been given to !denti­
fica.tion ot copper coJ:lJ)ounds.
::aowever, after the copper indieetions had been round
in the present sories of: collectio•,s, some collections were round on file that hod
been made on plain glycertn-3aui.tin on july .1,, 1949.
-These r.are oovered ,nth the
Sarun fi-lm and rubeanic eoid C!Jld an::.on1a were appliod by d1 tfusion through tho ·ttlm.
A few copper indications were found, al!nost all the i:e.rtioles being in the 30 micron
size group.
Some other co11ection.s were made early 1n ~uly tbo.t will be e::lt8!ninod
tor· 'lopper when they are treed !"roe other tests.
lil add1 t1on, oce~ional colloot1ons
will be examined. tor copper in the futll!'e, and 1t may be possible eventually to add
so:neth1ng to tho information now presented.
COllCLUSION6
REGARDING
COPPER
In view Qt the above fa.eta , it i,eem:, very hazardous to draw any: definite con­
clusion associating ~he coppe~-bearioo perticlos collected with the fireball or 1uly
24. Th.are a till is, hwoTer, a residuum or poasitdlity ot such associations men 1 t
is conoidored th c.t partic!.ss ot 1hc smallest s1 ze group did not appear in largo
numbera until some 35 hours at'ter the po.esege of tl;le fireball.

Attention is called particularly to the l arao !lumber ot small particles in one
at the 145-l/2-ho-.ir collootione.
The actual nl.I!lber in the colle'ltion was 140, tor
the r ive-oinute run.
l.!ost of these l'lere in the size range of' tTJO to f1ve microns•
and the principal difficulty in assoctattnc them 111 th the fireball is that a five­
micron par\1cle cannot tall J!lUOh more tho.n l0,000 foot in 145. 5 hom-s.
These part1­
olea could have ccr:ie down from a greater height only it' sol:!& downward motion hfld
tc.k:en place in port of the a1r 1nvolvet.
It should be oantioned. that collections were t aken during tbe at'ternoon of Ju13'
27, at several pointa eouth end east ot Socorro, tbs fartb.eot being near Binche:a.
These oolleotions ocntainod pcrtiole~ giving copper indications, the :particles being
i n tho •a;?¥!) range ot sizes as those collected in Socorro at about the &a.":le ti'C'.b.
It is perhaps noteworthy that the cop_per-boari ng particles 1n all these collec­
tlona were of opaque material.
I.oat ot the co:;,per minerals tbat h uve previously-
come to our attention 1n collection• rrom the air have been oolored material, blue,
green, red, or yellow.
C OBALT
AND
NICKEL TESTS
In the 2 t00 J.l•
coll~cti on of J"ul.y 26, three quite re:::iarkable particles were
found that save very strong coba1t indications.
The particles were apparently por­
:reot spheres (at l east thoy were pori'eetly circul.ar in cross section), twelve mic­
ro!ls in diameter.
The reaction with rubeanie e.eid, after at!nOnia trentmant , pi•o­
dueed a dense yellow-ten halo, eixty microns 1n diameter.
The color v.ao not quite
so clear es with pure cobalt:
the e.ppearance sU;;gestin.g e. high-cobalt com,vosition
with so~ metal. prosont.
Such particles are quite uniqne i n the axporionce or the
present. , It' these particles wore of meteoritic orictn they cwld, in tho absence
of verticul oir IJOV«llSnt, have f'al:len a d1stO!loo of the oi·der ot 20, 000 feet 1n an
i nterval or 41. 5 houra.
Two particlse giT1ns nickel indication.swore round. ~a is quite nomvl, llo ,­
ever.
It anything, the number is smaller than x::ight have been expected in material
of aurt'aoe ori<;in.
The collections ware not given acid treatnent: additional nickel
indieations might h &Te been 'i'ound it t his had been done.
A
oUOGEB TION
hile the r&aul.ta o!' the present investiga:Uou ahould be recarded as negatt-vo
or,inoonolusive, it i s desired to call attention to the faet that a coan.s ia at hand
that obould r..al:a .PQAsiblo a definite demonetration of tho presence or absonoe ot cop­
per :particl es asaod.ated with events or the July 24th type.
rartlo l.e collectlon equipment, operating on the s .:mie principle as that used in
the i:resont inTestigat1on, and der;igned tor airple::ie installation, is on hand and
1te suco&esful operation has been dooonstrated in numeroll s sligh:ta.

(Dr. Crozier and Mr. $eely have both agreed

Summary of Observations of Aerial Phenomena in the New
Mexico Area, December 1948 - Uay 1950
TO:
Brigadier General Joseph F . Carroll
Director of Special" Invest.i gations
Headquarters USAF
Washington 25 , D. c.
1.
In a liaison meeting with other military and government intel­
ligence and investigative agencies in December 1948, it was determined
that the frequency of unexplained aerial phenomena in the New Mexico area
was such that an or ganized plan of r eporting t hese observations should be
undertaken.
The organization and physical location of units of t his Dis­
trict were mo~t suitable for collecting these data , t heref ore , since
December 1948, this Distriet has assumed the responsibility for collect­
ing and r eporting basic information with respect to aerial phenomena
occurring in this general area.
These r eports have been distributed to
the Air Materiel Connnand, USAF , in accordance with Air Intelligence
Requirements No . 4, and to other interested military and government
agencies .
2.
Ther e is attached. as a part of this summary, a compilation of
aerial phenomena sightings that have occurred mostly in the New Mexico
area and have been reported by this District Office subsequent to
December 1948.
This compilation of sightings is not a complete r ecord
of all reported observations, but includes only those in which sufficient
information was available to justify their inclusion.
The observers of
these phenomena include scientists , Special Agents of the ·Office of
Special Investigations (IG) USAF , airline pilots , military pi lots , L:ls
Alamos Security Inspectors , military personne l . and many other persons
of various occupations whose reliability is not questioned.
This com­
pilati on sets forth the most important characteristics with r espect to
each observation and evaluates each sighting into one of thr ee classifi­
cations , (1) green fireball phenomenon , (2) disc or variation, and (3)
probably meteoric.

There is a lso attached an analysis of the green fireball
occurrences in this area made by Dr. Lincoln IaPaz .

May 1950
Dir ector of the Institute of Meteoritics and Head of the Department of
Mathematics and Astronomy at the University of New Mexico .
He was Re­
search Mathematician at the New Mexico Proving Grounds under ah OSRD
appointment in 1943 and 1944, and Technical Dir ector of the Opera·cion s ·
Analysis Section, Headquar ters, Second Air Force , 1944- 45. Since 1948,
Dr. LaPaz has served on a voluntary basis as consultant for this Dis­
trict in connection with the green fireball investigations.
4·•
On 17 February 1949 and again on 14 October 1949, conferences
wer e held at Los Alamos, New ~iexico, for the purpose of discussing the
green fir ebal l phenomena.
Representatives of the following organizations
were present· at these meetings : Fourth Arrrr:1 , Armed Forces Special ',1feo.­
pons Project, University of New Mexico, Federal Bureau of Investigation,
U. s. Atomic Energy Connnission, University of California, u. s. Air Force
Scientific Advisory Board, Geophysical Research Division Air Materiel
Command USAF , and the Office of Special Investigations (IG) USAF.
A
logical explanation was not proffered with respect to the origin of tho
green fireballs .
It was , however, genero.lly concluded that tho pheno­
mena existed and that they should be studied scienti fically until these
occurr ences have been satisfactorily explained.
Further, that tho
continued occurrence of unexplained phenomena of this nature in the
vicinity of sensitive installations is cause for concern.
5.
·The Geophysical Research Division, Air 11ateriol Command,
Cambridgo , Hassachusotts , ho.s recently let a contract to Land-Air , Inc.,
Holloman AFB, Alamogordo, New Mexico, for a limited scientific study of
green fireballs .
The results of this scientific o.pproach to the pr oblem
will undoubtedly be of great value in determining the origin of these
phenomena.
6.
This sununary of observations of aerial phenomena has been
prepar ed for the purpose of re- emphasizing and r eiterating the fact
that phenomena have continuously occurred in the New Mexico skies
during the past 18 months o.nd are continuing to occur, and , secondly,
that these phenomena are occurring in the vicinity of sensitive mili­
tary o.nd government installati ons .

Sig~ting No. 175
Photograph of Unknown Aerial Phenomena taken at De.til ,
New Mexico by Cpl Lertis E. Stanfield, Holloman Air Force
Base, New W~xico on 24 and 25 Feb 1950. An analysis of
the above photograph was made by Dr . Lincoln La.Paz, Head
of the Institute of ~~teoritics, University of New Mexico,
Al buquer que, New N~xico, who reached the following con­
clusions:
a o
Tl:e angular diameter of the perfectly round
luminous object Stanfield observed was approx­
imately 1/4 of a degree .
b.
The angular velocity of the object in the sky
was greater than half _a degree per minute .
Dr . LaPaz stated that on the basis of the results (a)
and (b) above, the object seen by Stanfield was not the
moon (for the angular diameter is too small) , it was not
Venus or any other pl anet (for the angular diameter was
too large), and it was not a bright fixed star slightly
out of focus (for the observed rate of motion is double
that due t o the diurnal rotation of the earth) .

17th District, O. S. I .
From:
Lincoln La.Paz, Director
Institute of 1Jeteoritics
Subject:
Anomalous Luminous Phenomena (Seventh Report)
1 .
In the second repor t of this series , dated 194:8, December 20, the
VIriter listed ten significant differences bet·,veen the bri~t f;reen horizon­
tally-moving fireballs observed in the interval 1948, Decer,tber ·5- 20 , aud
typical met eors .
These differences were the following :
( 1) The horizontal nature of the pat,1s of nost of t he December
fir eballs is most unusual.
Genuine meteors are rarely observed to move
in horizontal paths .
( 2) Again the very low hei ght of the December fireball discussed
in s ection 2 above sets it off in sharp contrast f rom the Genuine
meteors for which heights of the order of 40 or more ,niles are ~o • •
mally observed.
( 3) The velocity determined for the fireball of Dece~ber 12 is
much less than the velocities det ermined from typical meteors (and
yet is considerably greater than the speeds of the V- 2 Roc~ets or
jet planes or of conventional flar es) .
( 4) In the case of meteorites that penetrate to as low levels
as that determined for the fireball of D~cember 12 , the observed l u­
minous phenomena ar e always accompanied by very violent -noises .
No
noises whatever have been observed in connecti on with the various
December fi r eballs so far investigated.
(Note added on 1950, :¥.ay 23:
Possible exceptions to the noiselessness of green fireballs ar e t.:"le
incidents of 1949 , January 30, and 1949, December 4.)
( 5) Genuine meteors normally show r emar kable variations in
brightness, beginning as fine thin hair lines , which are scar cely
visible to the observer, and then brightening up to flash out near
the end of their paths .
In the case of the December firetalls most
of the observers have reported tha·G the green balls appear ed almost
instantly at their full br i ghtness.

to move horizontally .
However , a strictly vertical infall is a l so very
rarely observed in the case of gem~ine meteor fal ls .
3.
An analysis just completed of the t ime distribution of the s r een
fireballs so far observed permits us to add an 11th item to the list of
differences given in paragraph 1 above .
The graph of frequency versus
local time which accompanies the present r eport s11m-:s t hat the ma;cirn,un
frequency of sighting of green fireballs ( occurring at approxina-cely
2030) coincides in time v1i th neither the f r equency maxir.1um for ordinary
meteors (occurrin;; at approximately 0300) nor the frequency mazimtun for
meteorite falls (occurring at approximately 1600) .
4 .
Inspection of the graph referred to in pa.rB.gr aph 3 also will
show that most of the green fireballs have been siEhted in a t i me i nter­
val e:;...-tending from about 5 p .m. to 11 p .m. (:MST) .
This conceutr ation
might be even more pronounced if it were possible to screen -:>ut of the
secondary max:iJnum, around 2 a .m. ( :r.£T), all ordinary meteors wl:ich have
been mistakenly identified as green fireballs .
rnat such misj_de::i.tifica.­
tion has occurred is strongly suggested by the near coincidence in time
of the secondary maxi :'lum of the green fireballs and the well oste.blished
early morninG maximum of the ordinarJ meteors .
5.
Some significance may attach to the fact that tho timo i nterval
alluded to in paragraph 4 extends f rom about 7 a .m. to 1 p .m. in the Ural
r egion of t he USSR.
Since missiles movine; Y1ith velocitie s of tho or der
of those found for the green fireballs for which r eal path determinations
have been possible would travel from the southern Urals to new Mexico in
less than 15 minute s , a possible inter pretation of tho concentration of
sightings r eferred to in paragraph 4 is tho.t the z r een fireballs r esult
from guided missiles launched from bases in the Urals i n the r.-.ornin~
hours before cloudiness due to convection or blinding afternoon dust
storms can interfere with non- radar tracking , such as has been used by
the Optical Trajector.1 Section at Tlhitc Sands Proving Ground .
6 .
There is also a pronounced concentt"ation of green fireball
incidents on the four days , Friday , Saturday, Sundny , Monday , almost
a l l of the most widely observed incidents having occurre d on Saturday
or Sunday.
7.
It is a curious and fairly well- established fact that there
has been a distinct decline in the numbor of green fireball sightins s
during the last two months, within whicn. the number of so- called
11f ly­
ing saucer11 incidents in this region :,as attained an all- time high .
8.
Although I have r ecently r eceived from Dr . Joseph Ira.plan of the
Scientific Advisory Board a letter containing the statement "l'rankly ,

consider ·t;he most probable explanation of t he green fireballs ~o 1)e ·;;he
one e;iven in the first of the three parat;ra··hs be 1.m·, ,ihioh are quoted
from my letter of 1950, February 20 , to Dr. P . H. ·.i"yc}wff , Cliief .,·..t:,1os­
pheric Physics Laboratory , Base Directorate for Ceophys:..cal Researc:1.
The last two pan1{;r aphs quoted. beloY1 \'lell summarize rrr;/ r ecommendatic,:1.s
concerninc the green fireball problem:
nAs a preli minary to settinc; down the project recommend....tions
which you ,requested , I have very carefull-r r eviev;ed all uvaile.')le
fireball data ( observers I reports , transit measv.r e:nents , calculated
real paths , etc . ) coverin3 incidents from those of Dcce~ber 5 , 1948
to the extraordinary incident of Febr uary 7 , 1950, ,1hich ;-,as been
under intensive investi~ation for the J.e..st two week:: .
As a result
of this compre'.'lensive review , particuln.1·1~, as it relates to the in­
cident of Februar y 7, 1950, I feel con!pe lled to write you in some­
what different terms concernini::; my mm part in the proposed f ireball
project than I had in mind \'/hen we last discussed thi s matter .
In
brief , I have come to the cone]. usion that , on the be.sis of t l~e
evidence now available to me , I Y1oulc', not te jus·:;ified in r eco:rm ,end­
ing a. firebe.11 project.
In ~' opir..ion , this evicieace proves conclu­
sively that the fireballs reported on fall i nto one of t,::o catescrics:
Those of the fir st category ( ·the 1'1ajority ) are mcteori"i:e i'alls of
unusual , but certainly not of impossible , ma~~nit
1J.de , frequency c.nd
other characteristics ; t )1osc of the second ca-~egory ( tne minority)
are u. S . guided missiles undergoin~ tests i n the nei~~borhoods of
th0 sens:'..tive installations t'.1ey a.re desi'.:;ned to def'e;_1-d .
This
interpretat:i.on of the latter category is the one t~1e.t I p r oposed in
answer t o a qv.estic>n raised by Dr . 'i'eller a.t the first Los i'.lc~':los
conference on r'ebn:.ary 1 7 , 19"49.
It ,.ms not ta!cen seriously then
and I doubt tha.t i·c viill be tal:en seriously a·t tl~e present time .
However , even if my interpretation of t;te t:nconventione..l £'ireralls
is the correct one , it is obvious t'.1.at ·chose in posi-l:;ior. t o con!'inn
it should r efuse ~o do so .
11
"Only one cthc.r point need be str essed , namely, that if I nm
v1rong in interpretin co: the ;;uided missiles r.s ot U. S . ori:;in , t'.1cr..
certo.inl~r intensive , systo!Tlatic i nvesti ~:ation of t!:ose objects
should not be delayed until the termine.i;ion o-..' tiHi pr csen-~ aca.ci..,rn;ic
year .
Recent international devclopr:0nts cOJ;:pel ono to sense ·";he
imperative necessity of i mmediate investieation of the unconvent:i.on­
e.l green fireballs , in c?.se yo1..:. are in ,·1osscssio·.·, of i nfcr:nation
proving that t:b.ey are not U. S . miss:'..les .
11
11 If such ::.n immediate investir;a·l;ion uere to be undcr tc.J.:cr. , I
would r eco:r;:;iend t:1at Dr . Fred. L. -,fhipple , of Earvurd Collo~e Obsc;r­

Sille'.111ARY OF INFORMATION:
1.
This i s a comprehensive summary of all observations of unidenti-­
fied aerial phenomena possessing similar charc.cteristics whioh hava beeu
observed in the New Hexico- West Texas area.
The cor:imon charu.ct~ristics
. of most of the incidents are :
a .
Green color., sometiraes described as greenish-white, bright
green, yellow- gr een, or blue green.
b.
Horizontal path, sometimes with minor variations .
c .
Speed less than that of a meteor , but mor e than any knovm type
of aircraft.
d.
No sound associated with observations .
e .
No persistent trail or dust cloud.
f .
Period of visibility from one to five seconds.
2.
All of the incidents r eported do not possess all of the above
onaracteristics, but in each case one or mor e are present .
In nonis of the
reported incidents has any natural or :nan- made object :)Gen deternined to
be responsible .
3.
The body of this summary consists of a tabulation of observations
with notes attached to clarify or amplify certain of the more important
observations.
Note nu~bers 1, 3, and 5 a.rs taken directly from r epor ts
compiled by Dr. Lincoln LaPaz. , University of Now Mexico.
Dr . LaPaz is
i nternationally known and r espected as a meteoriticist, and he.s taken a
gr eat interest in these phenomena.
4.
The tabulation of sighti ngs is not a conplete record of all r e­
ported observations, but comprises only those in which int,,irvievrn Vlcro
conducted by OSI personnel.
Hany other p-.:::rsons we re interviewed by Dr.
LaPaz. and his. colleague s , but, inasmuch a s complete datu is not availabl e ,
these interviews are not taken into account in this summary.,

1.
On .L6 February,. a conference was held at Los Ala.mos to consider
the so-called green fireball phenomena which comnenced about 5 December
1948. The followring were present:
For Los Ala.moss
Mr. N. E. Bradbury
Mr. Marshall Holloway
Mr. Fred Reines
Mr. John Manley
Mr. Edward Teller
Mr. Elmo Morgan (AEC)
Mr. Sidney Neuber~er (Security)
Mr. Maxwell (AESS)
Mr. Hoyt
For the Fourth Army:
DEClASSiflEO
Major William A. Godsoe
Major Wynn
For the u. s. Air Force:
Captain Neef
For the University of New Mexico:
Dr. Lincoln La.Paz
For Sandia Bases
Commander Richard Mandelkorn
i. Captain Neef opened the meeting by saying that the problem was
being presented to Loa Alamos scientists in hopes that they would be able /
to indicate some mode of attack on the problem and offer some explana­
tions for the phenomena observed. He stated that this question had been
classified military SECRET under the name,. Project "Grudge",. and that the
investigation was now the primary responsibility of USAF,. Air Materiel
Command,. T-i. He then turned over the discussion to Dr. La.Paz.

18 February 1949
3. Dr. LaPu stated t:tat he had been assisting the Military for
the past two months at their request in the investigation of tho subject
problem. and want on with the general discussion of phenomena attending
normal meteorite fall. postulating the following important character•
istics s
a. Random path of fall.
b. Color and intensity variations in l ight emitted.
o. Sound.
d.
Frightened animal s .
4. Dr. LaPaz then went on to discuss the number of observers re­
porting the subject phenomena and the diversity or their backgrounds•
including commercial airlines' pilots, military pilots. special intelligence
agents. Los Alamos personnel (Mr. Hoyt). e.nd himself, as well as various
and sundry previously uninformed citizens.
5. Dr. LaPaz then described the "Starvation Peak Incident" which he
observed himself• detailing the following characteristics which indicate
that the phmomenon can not be classified as a normal meteorite falls
a. Initial bright light (no period of intensity increase} and
constant intenRity during the duration of the phenomenon.
b. Yellow-green color (about 6,200 angstroms).
c. Essentially horizontal path.
d. Trajectory tra.versed at constant angular velocity.
e. Duration about two seconds.
r. No accompanying noise.
6. Since about 5 December 1948. there have been more than ten in­
cidents analogous to the "green fireball" described, and some twehty more
presenting minor deviations to the above. which should be oonsiderod in
connection with them.
In addition. there have been a number of normal
shooting stars and meteors observed.
7. There ensued a general discussion in which it was brought up that
the majority of the observers whose reports were here under consideration
were not subject to previous psychological infiuences or prior knowledge
as to what they should look for. Furtherr.iore. •seeing.. conditions for
meteor observation throughout the continental United States were at least

average during December., January., and February., yet no green fireballs
have been reported in any other areas. They seem.ad to be confined to the
Los Alamos, Las Vegas., and Vlest Texas triangle.
8. Mr. Teller then took over the discussion and showed that a
material object travelling with the velocity of the subject phenomenon
(about eight miles per second) would have to have a mass of about twenty
grams, assuming all the kinetic energy could be converted to light, under
the assumption that the light output is in the vicinity of 10
ergs per
second. He then went on to show that the shock wave produced by the
passage of an object or these dimensions or greater passing through the
atmosphere at a height of eight to ton miles (the observer fi£ures) with
a velocity of eight miles per second would produce a loud noise easily
audible ten kilometers from the source.
No sound has been observed.
Therefore, Mr. Teller has the tentative opinion they are not material
objects passing through the air.
We should look to electronios and
optics for an explanation rather than in the field of hydrodynamics.
In
any event., it was apparently agreed by those present that it-was almost
incredible that a large object such as a guided missile or informer
vehicle could pass through the atmosphere at a height of eight miles at
a velocity of seven to eight miles per second without producing a loud
noise wnich would have been audible to observers. Mr. Bradbury demurred
so far as the electronic explanation was concerned, saying if it were assumed
that the answer lay in t hat region, many more difficult problems would have
to be solved.
9. The following aotion seems in order:
a .
Recalculation of the data outlined by Mr. Teller with a more
accurate treatment to verify his tentative conclusions.
b. The establishment of woll-equipped and organized observation
stations to give as thorough photometric and photographic coverage as is
possible in the geographic area involved.
c. Assuming that Mr. Teller's theories are borne out by re­
calculation, declassification of the .Project to permit participation and
thinking by scientists tnroughout tho country.
10. Dr. Le.Paz and Captain Neef have fruitlessly attempted to obtain
information from a ?ll8teorite observers' group now at Vlhite Sands, said to
be performing work under contraot for the Navy.
Commander Mandelkorn
offered to assist them in their endeavor to enlist the servicos of the
group for observntions in connection with Project "Grudge".
11. Conclusions It is my belief that these phenomena, •particularly
if there are any further incidents., a.re deserving of serious consideration
•See next page.

until their source and meaning have been sntiefactorily explained.
Although Mr. Teller's discussion tends to disprove the hypothesis that
guided missiles or informer vehicles are responsible, thero is cause
for concern of the continued occurrences of unexplainable phenomena of
this nature in the vicinity of sensitive installations.
•Captain Neef reports blue fireball visible from Sandia at 0530, 17

until 1806, 17 Fobruary.
