1951 Project GRUDGE Status Report No. 2 ATIC Reported UFO Sightings

This U.S. Air Force document is Status Report No. 2 of Project Grudge (Project No. 10073), authored on or near 31 December 1951 by the Air Technical Intelligence Center (ATIC) at Wright-Patterson AFB, Dayton, Ohio. It was classified Confidential and later declassified per a Secretary of Defense memo dated 2 August 1960; it is archived by the Defense Technical Information Center (DTIC) as AD0128982. The report covers the project's activities from 30 November 1951 to 31 December 1951, including sorting and filing of Project Grudge and Project Sign records (roughly 800 incidents dating back to 1946), preparation of summary and cross-index cards, a national map for plotting sightings, and the engagement of scientific consultants in physics, nuclear physics, astronomy, and psychology. It notes delays in obtaining sighting information and a belief that many sightings go unreported. The bulk of the file is a tabulated summary of unidentified-object sightings from August through December 1951 with date, location, time, description, speed, altitude, heading, source, and conclusions. Eight appendices provide detailed accounts, including the Lubbock, Texas lights observed by Texas Technical College professors (with photographs analyzed by Wright Air Development Center), an Albuquerque flying-wing sighting by a Sandia Base security guard, the Matador, Texas pear-shaped object, the March Air Force Base F-86 interception attempts (assessed as possibly a radiosonde balloon), and sightings over Terre Haute and Paris, Minneapolis, and Southern Michigan. Many incidents are recorded as having no conclusions or being attributed to meteors, fireballs, or balloons.

Description

The second monthly status report of Project Grudge, produced by the Air Technical Intelligence Center at Wright-Patterson Air Force Base. Originally classified Confidential (later declassified), it summarizes unidentified aerial object sightings reported from 30 November to 31 December 1951, describes the overall status of the project's files and investigations, and details specific incidents in eight appendices, including the Lubbock Lights and the Albuquerque flying-wing sighting.

Claims

  • A prominent research organization and other engineers and scientists concluded, after inspecting the files, that there were enough reports unexplained by known objects or phenomena to warrant a detailed scientific investigation.

    75%
  • Approximately 800 UFO incident reports dating back to 1946 were on file at ATIC and were being sorted, filed, and cross-indexed.

    80%
  • The Lubbock lights photographs were inspected by Associated Press and Life Magazine representatives and, per WADC analysis, were not obviously a hoax; lights varied in intensity and changed position.

    70%
  • The March AFB object was very possibly a radiosonde balloon released from Long Beach Municipal Airport, though the third attempted intercept could not be explained.

    65%
  • Many sightings of unidentified objects were believed not to be reported at all.

    70%
  • Some sightings were attributed to migratory birds (ducks reflecting city lights), meteors, or the green fireball phenomenon.

    65%

Events

  1. Aug 24, 1951

    Matador, Texas pear-shaped object

    Two women reported a pear-shaped aluminum object that hovered then ascended rapidly north of Matador, Texas.

  4. Sep 20, 1951

    March Air Force Base F-86 interceptions

    Multiple F-86 aircraft from George AFB attempted to intercept an unidentified object near March AFB; assessed as very possibly a radiosonde balloon, though one turn could not be explained.

  5. Nov 23, 1951

    Southern Michigan multi-witness sighting

    Seven people from four locations observed an unidentified aerial object in southern Michigan traveling faster than a jet.

+hfi inridents dating back to 1946 that are in ATIC have been sorted and filed.
S:rrj:?a^roJlSLr800 on file. Each incident has been put in a separate
folder and filed in chronological order.
Sumoary cards are being made on each incident. These sum^ c^ds

B.

Missing Reports and Photographs

It is apparent that the details of some of the reports between early
1949 and mid-1951 are missing. An attempt will be made to obt^n these r^rts
other agencies so that the ATIC file will be complete.
ferred to in some reoorts are also missing. Although there have ^t been
many photograohs of alleged unusual aerial objects ^^t^ to
^
been a few and an attempt will be made to obtain prints of these photographs.
C.

Map for Plotting Sightings

A large nap of the United States is being prepared and is nearly comnleted. All of the sightings will be plotted on this man in an attempt ^
establish some pattern in the sightings. A color code win be
that as much information as possible can be granhicany mustrated on the map.
D.

Delays in Obtaining Inforiaation

It wni be noted in the list of incidents that is contained in this
report tlaat the investigations of sightings reported several months
still pending or that some sightings have not been investigated due to the tame
that has elapsed since the sighting. The investigations being conductea in
conjunction with the project are still being hampered by the aelays in receiving information.
*•
On ?5 October 1951, it was requested that AFOIN-GG-1 letter dated
8 September 1950 subjects -Heporting of Information on Unconventional aircraft
be revised and recirculated to all ivF commands. It is honed that as soon as
this is done the situation will improve.

CONFIDENTIAL

i/-.:

I
‘

A

confidential
In addition to delays in receiving additional infomation, it is believed that many sightings of unidentified objects are not being reported at all*
Thie belief is founded on the fact that ATIC has received newspaper clippings or
requests for information on sightings about which there is no information in the
records.
E,

Consultants

Several conferences have been held with members of a prominent research
organization to determine whether or not there is enough information available
on the xmidentified aerial objects to warrant a thorough scientific investigation.
These peoole have inspected the files, discussed the oroblem, and it is their
opinion that there are enough reports that cannot be explained by known objects
or phenomena to warrant a detailed investigation.
Several other prominent engineers and scientists have been contacted
and their opinions are much the same as those stated above.
Negotiations are underway to obtain the services of consultants in the
fields of physics, nuclear physics, astronomy, psychology, etc., to assist in
the analysis of the reports. These consultants will also attempt to make a
continuing statistical analysis of the reports in an attemot to determine
whether or not there is any significant pattern or characteristics in the
sightings. In this respect, it is hoped tliat the project can receive tlie full
cooperation of all AF commands in promptly reporting all sightings of unidenti^
fied aerial objects, so that as many authentic reports as possible will be
available for study by statistical analysis.

LUBBOCK. TEXAS - 25 August 1951
I.

DISCUSSION OF THL INCIDENT

The first of a series of sightings related to this incident occurred the
evening of 25 August 1951 at approximately 2110 CST. Foinr Texas Technical College
professors were sitting in the backyard of one of the professor's homes observing
meteorites in conjunction with a study of micrometeorites being carried out by
the college. At 2120 they observed a group of lights pass overhead from N to S.
The lights had about the same intensity as high cirus clouds on a moonlight night.
The altitude was not determined but they traveled at a high rate of speed. The
pattern of the lights was almost a perfect serai-circle containing from 20 to 30
individual lights. Later in the eveniug a similar incident was observed and
dviring a period of about three weeks a total of approximately twelve (12) such
flights were observed by these men.
The group of men included;
a.
b.
c.
d.

The Head of the Petroleum iingineering Department
Professor of Geology, has PhD.
Professor of Physics, has PhD.
Professor of Chenical Engineering, has PhD.

Besides the above four men, the following have observed the incidents;
a.
b.

Professor of Mathematics, has PhD.
Graduate student working on PhD.

In addition, a Professor of Astronomy was consulted on tlie incident, but he did
not observe any of these flights.
The above mentioned men took a personal interest in the phenomena and xmdertook a study of the objects. Attempts were made to obtain an altitude measurement by laying out a measured base line perpendiciJ.ar to the usual flight path
of the object and placing angle measuring devices at the end of the base line,
however, all their attempts failed because the objects did not appear on the
nights the observers were waiting for them.
Prom the series of observations, the following facts were obtained;

-i

a.

The angular velocity of the object was very nearly 30° of arc per second.

b.

There was no sound that could be attributed to the object.

c.

The flight path of the object was from N to S in the majority of the
flights although some were KE to SW.

d.

On several nights there were two or tliree flights.

■CONFIDENTIAL

■3,

e.

The color of the lights was blue-green.

f.

There were from 15 to 30 peparate lights in each formation.

g.

The first two flights observed were a semi-circle of lights but in
subsequent flights there was no orderly arrangement.

h.

The object always appeared at an angle of about 45° from horizontal in
the north and disappeared at about 45° in the south. The object did
not gradually come into view as would an aircraft aporoaching from a
distance, neither did it gradually disappear.

i.

There was no apnarent change in size as the object passed overhead.

j.

The "angular span" was estimated to be 10°.

Attempts were made to obtain the relative height of the object in respect
to clouds. However, these attempts were also unsuccessful due to the fact that
the objects passed between widely scattered clouds.
Attempts were made to determine whether or not there was any form between
the lights by trying to see stars between the lights. These also was unsuccessful due to the short time the object was in view.

li

This ohenomena was observed by at least one hundred people in ano around
I^bbock, Texas. Some ol* these people were of the ooinion that the objects
were birds reflecting lights from the city.
On the evening of 31 August 1951 at about 2330 GST, a college freshman from
Texas Tech observed a flight of the unidentified objects pass over his home. The
flight was observed through an open window. Upon observing the first flight of
the objects, the observer obtained his camera and went into the backyard of his
home in an attempt to get photographs of additional flights of the object.
(Comments This would be logical as by 31 August 1951 these flights of the objects, and the fact that several flights might occur in an evening, was well
toown.) Two more flights of the object allegedly did occur and were photographed.
Two photos of one flight and three of another were obtained. ATIC has foxir of
the negatives but the other one was lost or misplaced by the photograoher. The
photographs show a V-shaped fonation of lights. In one j5hoto a singie-V of
lights appear, while on three photos there is a double-V. The seoarate lights,
which appear to be pinpoint light sources, vary in intensity.

A trip was made to Lubbock. Texas, on 6^9 November 1951 to obtain more

Pfess and Life i-lagazine representatives. It was their opinion that the ohotos

or not the photographs were of the sane objects that they had observed because:
1. They had never observed a V-shaped formation of lights. This is
not too significant, however, as the arrangement of the lights that they observed
varied and s^ce there were several flights the college professors possibly did
not see the flights that were photographed. In addition, the ohotogranher states
that toe object appeared to be U-shaoed but when he developed toe negatives, the
object was V-shaped.

On the evenin^r of 25 Auprust 1951, at 2158 MST, a Sandia Base Security Guard
and his vrife observed what they described to be a flyinp wing type aircraft
similar to the Northrop Fly-Uing Bomber (B-49) pass over the backyard of their
trailer home in the east part of Albuquerque. Ihey judged the wing span of the
aircraft to be about one and one half tines the wing span of a B-36, with which
they^were familiar. Ihe object was fljdlng low, the 'altitude was thoiight to oe
about 300 ft. - 1000 ft., and there v;as no soima that coxild be attributed to
the object, ihe color of the object was not apparent due to the twilight but
dark chordwise stripes were noticed under the wings. Six to eight pairs of soft
flov/ing lights were noticed on the trailing edge of the wing. The speed was

On 31 Aupust 1951 at approximately ld45 GST two ladies were driving in an
automobile several niles north of Matador, Texas. The object was described as
a pear-shaped object about the length of a B-29 fuselage, aluminum or silver in
color, which readily reflected the sunlight. The object had a port or some type
of aperture in the side and moved throvigh the air with the smal1 end forward.
There was no sign of any exliaust and no noise was heard.

As the two ladies were driving north from Matador, Texas, the driver of
toe automobile first noticed the object about 150 yards ahead of the automobile.
They stopped and both ladies got out to observe the object. It was drifting
slowly in ^ eastward direction at a sneed they judged to be 'less than the
speed required to take off in a Oub aircraft and an altitude of about 120 ft.
Seconds later the object began to ascend rapidly and moved out of sight into
tne wine in a circular ascent. {The wind at this tine was from IE at about
5-7 knots.;
A background investigation showed that both womm were of evcellent
character.
This incident is of interest because it was observed during toe same

I.

DISCUSSION OF INCIDErrr

The first report of this incident, which appeared in Status Report No. 1,
proved to be incomplete and misleading. Further investigation has corrected the
discrepencies and the following account of the incident is considered to be
accurate.
r

At approximately 0700 PDST, two F-86 aircraft were scrambled from George Air
Force Base, California, on a routine mission. The flight was vectored to 118°
40''.! - 33® 50'N by GCI. (See inclosed overlay.) The flight orbitted the position
and took up a heading ujward Long Beach Radio. At approximately 0755 PDST the
flight reported to GCI that they observed an unidentified object high at 12 o'clock.
The flight was 30 seconds out of Long .ieach Radio at this time. The object appeared to be in a left orbit at about 50,000 ft. The object could not be picked
up by the ground radar, however, visual contact was maintained. The object continued a left orbit and passed over tJie two aircraft. Attempts were made by
the F-86's to identify tho object but they were unsuccessful due to the altitude
of the object and a fuel shortage. At approximately 0810 or 0815 the flight was
released by the ground controller and they returned to George Jiir Force Base.
The object appeared to be an aircraft with 45® swept wings and bright silver -in
color. When last seen the object was in a left orbit, or circling to the left.
The pilot's opinion was that it was a swept xdng type aircreift.
At approximately 0800 PDST four additional F-86 aircraft were scrambled
from George AFB to relieve the two above mentioned F-S6's. The four aircraft
split into two, two-ship elements, denoted as Flight 2-A and 2-3 on the inclosed overlap". Flight 2-A was vectored to a position at 117° 30'W and 30°
20'N. They arrived at this position at approximately 0810 and sighted the
object high at 1.: o'clock at what appeared to be over ihiroc AFB. A steady
climb was made to 43,000 ft. and tlie object was found to be near March AFE.
The object appeared to be in a controlled orbit to the right and left at 50,000
to 55»000 ft. The two aircraft stayed in the area for 10-15 minutes before breaking off the intercept due to a fuel shortage and landed at 0845 KDST, The object
appeared to be a swept wing aircraft.
The second element of the group, noted as Flight 2—B on the overlay, observed
the object soon after take-off. The object appeared to be going south. The
flight made a series of climbing turns under the object as they climbed to 4?,500
ft. The object was in a wide right turn. At approximately 0925 PDST the aircraft
broke off the attempted intercept and returned to their base. This flight reported that the object apoeared to be round and silver.
No more intercepts were attempted. At no tine was the object observed on
the radar screen nor was it reported to be observed visually from the ground.
The F-86's, however, were contin ally tracked by radar.

DISCUSSION OF THE INCIDENT

On 9 October 1951 at 1342 CST, a CAA Chief Aircraft Conaiunicator observed
a silver object pass directly overhead while he was at ifulman hJunicipal Airport
five miles east of Terre Haute, Indiana. The object was judged to be approxi- *
mately the same size as a 50 cent piece held at arm's lengtli. The object passed
overhead at a very high rate of speed going in a southeasterly direction, passing
from direcUy overhead to the horizon in about 15 seconds. There was no sound ot
vapor trails. 'Ihe shape and general form of the object could be seen as the object
passed over the horizon and out of sight.
