The FBI's 62-HQ-83894 case file includes investigative records, eyewitness testimonies, and public reports concerning Unidentified Flying Objects and flying discs documented between June 1947 and July 1968. The records include high-profile incident accounts, photographic evidence from sites like Oak Ridge, TN, and technical proposals regarding potential propulsion systems. Additional topics include convention programs, researcher accounts, and extensive media coverage from the period. This file is partially posted on FBI vault with more redactions and some pages missing. Included here is the complete case file with several newly declassified pages and only minor redactions.

described as green fireballs, discs and meteors in the vicinityµ~

Expert of the University of New Mexico, reported that the phenomena

with Land-Air Inc ., Alamogordo, New Mexico, to make scientifi?·c ri
study of the unexplained phenomena.

NATURE OF PHENOMENA
Observations of aerial phenomena occurring within the
vicinity of sensitive installations have been recorded by the
Air Force since December, 1948. The phenomena have been
classified into 3 general types which are identified as follows :
1. Green fireballs, objects moving at high speed
in shapes resembling half moons, circles and discs emitting
green light.
2 . Discs, round flat shaped objects or phenomena
mouing at fast ueloci~y and emitting a brilliant white light
or reflected light.
3. Meteors, aerial phenomena resembling meteor ic '
material moving at high velocity and varying in color.
The above phenomena have been reported to vary in
col or from brilliant white to amber, red and green.
Since 1948, approximately 150 observations of aerial
phenomena referred to above have been recorded in the vicinity
of inst allations in New Mexico . A number of observations have
1 been reported by different reliable individuals at approximately
the same time.

RESULTS OF AN INQUIRY BY PROFESSOR LINCOLN LA PAZ
Dr. LaPaz, Director, Instttute of Meteorittcs,
University of New Mexico, submitted an analysis of the various
observations on May 23, 1950. He concluded, as a result of
his investtgation, that approximately half of the phenomena
recorded were of meteoric origin. The other phenomena
commonly referred to as green fi reballs or discs he believed
to be U.S. guided miss-iles being tested in the neighborhood
of the installations. Dr. LaPaz pointed out that tf he were
wrong in interpreting the phenomena as originating with U. S.
guided missiles that a systematic investigation of the obser­
vations should be made immediately. Dr. LaPa2 pointed out that
missiles moving with the velocities of the order of those
found for the green fireballs and discs could travel from the
Ural region of the USSR to New Mexico in less than 15 minutes.
He suggested that the observations might be of guided missiles
launched from bases in the Urals.
i)'
On the basis of the investigations made by Dr. LaPa2
and the Air Force, it was concluded that the occurrence of the
unexplained phenomena in the vicinity of sensitive installations
was a cause for concern . The Atr Force entered into a contract
)
with Lard-Air, Incorporated, Alamogordo, New Mexico, f or the
purpose of making scientific studies of the green fireballs and
dtscs. It was pointed out in the summary furnished by OSI on
July 19, 1950, that the unexplained greenfireballs and discs
are still observed in the vicinity of sensitive military and
l)
Go,pernment installations.
RESULTS OF AIR FORCE INVESTIGATION
The Air Force together with Land-Air, Incorporated,
have established a number of observation posts in the vicinity
of Vaughn, New Mexico, for the purpose of photographing and
determining the speed, height and nature of the unusual
phenomena referred to as green fireballs and discs. On May 24,
1950, personnel of Land-Air, Incorporated, sighted 8 to 10
objects of aerial phenomena. A 24~'fljur day watch is being
)
maintained and has been designated ~ roJ·ect Xw}qkl~_."

CONCLUSIONS
The Albuquerque Office, in a letter dated August 10,
1950, advtsed that there have been no new developments in connection
with the efforts to ascertain the identity of the strange aerial
phenomena referred to as green fireballs and discs . The Albuquerque
Office advised that Dr . Anthony o . .Mirarchi, Project Engineer,
had been informed of the Bureauajurisdtction relative to espionage
and sabotage and arrangements have been made so that the Bureau
will be promptly advised in the event additional information relative
to this project indicates any jurisdiction on the part of the
)
Bureau. .

SAC Cornelius of Philadelphia called at 10:45 A.JI. Be!Jlollt__
today and stated that yesterday evening while two offi cers of 11011r__
the Philadelphia Police Depar-tment were cruising in their Tole. Hooa_
scout car they saw through the windshield an object descending
slowly to t he earth which appeared at first glance to be a
parachute .
When the of ficers first noticed the object, it was a
tree-top level and was described as being six feet in diameter.
It landed in a field near-by and the officers, upon examining tt,
noted that it gave out a purplish glow which was almost a mist.
The officersrummoned two other police officers. After looking
at the object for some time they attempted to pick it up. The
object broke, leaving a slight odorless residue. Over a period
of about 25 minutes which the officers spent watching the object
it completely disintegrated. The officers further commented that
the object was so light that when it hit the field, it did not
even bend the weeds or the grass it fell on .
Jlr. Cornelius said that he has called the local of fi• e
of the Air Force but the individual with whom he sp oke there said
he knew nothing about them and was not aware that his office was
looking into reports of this type•
.Mr. Cornelius desired to know what furthe r action should
be taken by him.
I told Jlr. Cornelius that he was correct in referring
this matter to the local office of OSI and that he should direct
a letter to the Bureau incorporating all available information
concerning the matter and that we here, upon it s receipt, in turn
would bring it ~o the attention of OSI Headquarters.

craft will be included in this report.
b. Priority of tran~J!lisaion accorded the report will be
that a.:p-propriate in the Judgm1a1~t of the forwarding agency, accord­
ing to its apparent authenticity and importance as intelligence.
c. Reports will be forwarded to Commanding General, Air
Materiel Command, Attention: MCIS.
d. Renorts forwarded by electrical transm1es1on will
include, as far aa possible:
(l) A brief description of the obJect(e); its ehe.pe,
