DOW-UAP-D100 — Air Materiel Command Report on Unidentified Flying Objects, 1947-1948

TL;DR

November 1948 report recommends silence, because balloons make more noise than UFOs.

• DOW-UAP-D100, Air Materiel Command report, Department of War, covering 1947‑1948.
• Investigated ~180 sightings; identified balloons, Venus, few unexplained high‑speed cases.
• No conclusive proof that unidentified flying objects are real aircraft.

l. By letter dated 30 December l947 from the Director of
Research and Development, Headquarters USAF, your Headquarters
was required to establish Pro ject "SIGN".
2. The conclusion appears inescapable that some type of
flying object has been observed. Identification and the origin
of these objects is not discernible to this Headquarters. It is
imperative, therefore, that efforts to determine whether these
objects are of domestic or foreign origin must be increased until
conclusive evidence is obtained. The needs of national defense
require such evidence in order that appropriate countermeasures
may be taken.
3. In addition to the imperative need for evidence to permit
countermeasures, is the necessity of informing the public as to
the status of the problem. To date there has been too little data
to present to the public. The press, however, is about to take it
into its own hands and demand to be told what we do or do not know
about the situation. Silence on our part will not long be accept-
able.
4. Request immediate information as to your conclusions to
date and your reconmendations as to the information to be given
to the press. Your recommendation is requested also as to
whether that information should be offered to the press or with-
held until it is actively sought by the press.

1. In attempting to arrive at conclusions as to the mture of uniden­
tified .flying object incidents in the United States, this Command ha.a me.de
a study of approximately 180 such incidents . Data derived from initial re­
ports have been supplemented by .further information obtained from check
lists submitted by mail, from interrogations of other field agencies, and
by personal investigation by personnel of this Command in the case of in­
cidents that seem to indicate the possibility of obtaining particularly
significant information.
2. The objects described fall into the following general classifica­
tion groups, according to shape or physical configuration,
a.
b.
in flight.

Flat disc of circular or approximately o:l.rcular shape .
Torpedo or cigar shaped aircraft, with no wings or fins visible

c.

Spherical or balloon shaped objects.

d.

Balls of light with no apparent form attached.

3. Some of the objects sighted have definitely been identified, upon
further investigation, as weather or upper air scientific balloons of some
type . A. great many of the round or balloon shaped objects indicated in
paragraph 2c above are probably of the same nature, although in most cases,
definite confirmation of that fact has been impossible to obtain.
4 . Some of the objects have been identified as beiilg astro - physical
in nature . For example , in daylight sightings, the planet Venus has been
reported as a round, silvery object at extremely high altitude . Action is
being taken to obtain the services of a prominent astro-physicist as a oon•
sultant, to study all of the incidents to determine l'lhether some can be
identified as meteors, planets or other manifestations of astral bodies .

.,

s. Arrangements for accomplishing a study of the psychological problans
involved in this project are being made in coordination with the Aero-Medical
Laboratory at this Headquarters . The possibility that some of the sightings
are halluoir:a tions, optical illusions or even deliberate hoaxes has been considered.

s. Although explanation of many of the incidents can be obtained from
the investigations described abOV'e, there remains a certain number of re­
ports for which no reasonable everyday explanation is available. So far,
no physical evidence of 'the existence of the unidentified sightings has
been obtained. Prominent scientists, including Dr. Irving Langmuir of the
General Electric· Company, have been interviewed to determine whether they
could advance any reasonable explanation for characteristics exhibited by
the objects sighted. In an early interview, Dr. Langmuir indicated that
these incidents could be expl&ined, but insufficient data were available
at that time on which to base definite conclusions. It is planned to have
another interview with Dr. Langmuir in the near future to review all the
data now available, and it is hoped that he will be able to present some
opinion as to the nature of many of the unidentified objects, particularly
those described as "balls of light."
7 • All information that has been made available to this Headquarters
indicates that the discs, the cigar shaped objects, and the "balls of light"
are not of domestic origin. Engineering investigation indicates that disc
or wingless aircraft could support themselves in fli1?11t by aerodynamic means.
It is probable that the problems of stability and control could also be
solved for such aircraft. However, according to current aerodynamic theory
in this country, aircraft with such configurations would hl.ve relatively
poor climb, altitude and range characteristics with power plants now in
use.

a. The possibility that the reported objects are vehicles from another
planet has not been ignored. However, tangible evidence to support con­
clusions about such a possibility are completely lacking. The occurrence
of inoidents ill relation to the approach to the earth of the planets Mercury,
Venus and Mars have been plotted. A periodic variation in the frequency of
incidents, which appears to have some relation to 'the planet approach curves,
is noted, but it may be purely a coincidence•
9. Reference is made to "The Books of Charles Fort" with an introduc­
tion. by Tiffany Thayer, published 1941, by Henry Holt & Co., New York, N. Y.
It appears that simular phenomena have been noted and reported for the past
century or more.
10.

In view of the above, the following conclusions are drawn,

a. In the majority of cases reported, observers have actually
sighted son-, type of flying object which they cannot classify as en air­
craft within the limits of their personal experience.

T-73017

Page 9

Ba.sic ltr fr Hq USAF, 3 Nov 48 to CG, AMC, "Flying Object Incidents in
the United States"
b. There is as yet no conclusive proof that unidentified flying
objects, other than those which are known to be balloons, are real aircraft.
c. Although it is obvious that some types of flying objects have
been sighted, the exact nature of those objects cannot be established witil
physical evidence, such as that which would result from a crash, has been
obtained.
11. It is not considered advisable to present to the press information
on those objects which we cannot yet identify or about which we camiot pre­
sent any reasonable conclusions. In the event that they insist on som,
kind ot a statement, it is suggested that they be informed that m.a:cy ot
the objects sighted have been identified as weather balloons or astral
bodies, and that investigation is being pursued to determine reasonable
explanations tor the others .
12 . A report, summarizing the results obtained from analysis of the
data and a technical investigation of the engineering aspects of -the objects
described, is nearly complete, and a copy will be forwarded to your Head­
quarters in the near future .

Assceiation was with the understanding that such srrangencnts sere to be
made, or had been made, by Projeet sIGn personnel. This was the deaision
made as a reault of the ccnference held at this Headquarters 27 July l948.
JAnap la6 was forwarded marely as being of possible value in the estab-
lishment of a direct reperting systen by airline pilots.
2. It is thorefore requested that Projeet Si gn pursotuel make ar-
rangemonts to onlist the serviees of the Air Tranaport Anscciaticn in
order to develop a aystun whereby U. S. airline pilots could make flash
reports of any unusual aerial sightings direct to your Headquarters.
3. In this cennection it.is suggested that the "Eesential Elenents

EXHIBIT "A"
Projeet Sign Study Requirements
The possibility that some of the unidentified aerial ebjects
that have been reported both in tne United States and in foreign
lands may have been experimental spaceships, or test vehieles for
the purpese of assisting in the development of spaceships, has been
given consideration by this Command,
If sueh craft actually have been sighted, it is believed more
likely that they represent the effort of a foreign nation, rather
than a produet from beyond the Earth.
Present world knowledge, techniques and resources are probably
adequate to meet the requirements for spaceship construction, or at
least to establish the preliminary experimental foundation for such
an accomplishment in the near future.
In any case, the design and periormance parameters of the craft
would necessarily be in confermance and consistent with the established
principles of our sciences.
To assist in the collection of infermation, relating to unidenti-
fied aerial objeets that may possibly represent spaceships or spaceship
test vehicles, and to assist in the analysis and evaluation of such re-
ported craft, technical information that includes the distinguishing
design and periormance parameters for spaceships is considered neces-
sary.
While such information is contained outright, or implieitly, in
the series of Rand Project reports, it would be of much value to this
Command to have a list of the special design and performsnce charac-
teristics that are believed to cistinguish spaceships, together with
any further scientific elues that might assist in their deteetion
and identification, prepared by Rand scientifie personnel.
