15. No evidences of outward propulsion were evidenced by objects.

16. Object definitely had no fins, stabilizers or elevators.

17. Objects had no slots or duct openings.

18. Objects had a sveed of about 1500 miles per hour, Informant

was not able to accurately estimate this speed. Speed rating was

obtained by finding the time the objects took to pass between knom

ints.

196 Objects according to informant, sounded like a siren and the
sound was continuous,

20. Six of the objects faded from view according to informant. Two
of the objects crashed in the surrounding area. The possibility
of fragments or other physical evidence was taken into consideration
and a three day search was instituted, grappling hooks being

employed for the object that was supposed to have crashed into
the water.

RELATIVE TO THE OBSERVER

1.
2. Semcon. West Yellowstone, Montana
36

l. Hebgen Lake Lodge, ‘Jest Yellowstone, Montana

a. age is employed by Mr. age, ,
of theggeiNe and has been employed as a

for

roximately two months as of 9 august 199. Mr.

duties entail that he also be in charge of the

boat landing and dock area.

S.- Observer's hobbies are his business, namely, huntinz and fishing,
Observer has had limited exmerience, little formal education
and is virtually without qualification as pertains to aeronautical
matters,

6. The observer should be a good judge as to the determination of
color, size and speed of objects, however, after conversing with
observer for a period of three days, it was felt that he is
extremely prone to exaggerate, particularly as to the speed
and number of things.

7- The employees of the Lodge seemed to agree that hr, GUE was
a very reliable individual, regarding him as a sort of "jewel"
in the rough. They believed that because of his experience as
a guide that he would be exceptionally well qualified to judge
speed, color, size, and to be possessed of a quick and discerning
eye. They stated that he knew nothing of "flying discs", never
having read about them at all, (This statement was open to
doubt, inasmuch as an article about "flying discs" was in the
boathouse where informant worked), It was agreed by all
that the would be able to take us directly to the
objects. This he failed to do in almost three days of searching.
A check with uty Sheriff @umg§ky .est Yellowstone, indicated
that Mr. had an excellent reputation, was considered an
excellent ggm@lleand had a fair reputation for being truthful,

Mr. “Q0M employer of Mr. QM stated that
he would unqualifiedly believe pee that ethe latter

stated as being the truth. Mr. ‘and Mr, ii.

have both known Mr, QM for a period of at least five
years.

Informant states that his attention was brought to the
object by the sound thereof; that it had a high, continuous
sound analogous to a siren,

There were no other witnesses obtainable other than the
observer. The observer reported that there had been a camper
in the area who observed the same incident at the same amd
time and place. He had not obtained the camper's name and
the camper had since moved on, No information could be
obtained from the records of the £2 OES relative

to the name of the camper. The “est Yellowstone area has a
great number of similar tourists during this time of the year.

1. Enclosed is a consolidated report of unidentified serial ob fects
observed by me~bors of the Field Force between the hours of 2700 - 11 August

2. While the reports obtained from interviewing various sembers of
the Field Force, wetek differed in some details, there was goneral agreenent
on the followings

a. The umisual lights were initially observed in the north and
moved in a southernly direction. .

b. Color of objects and trails was white.

¢c. Distance from observer to light was unestimable.

Gd. Period of observation from 3 to 5 seconds.

ce. Straight level flight of object.

f. Moving light went out in a fraction of a second.

3. It is the considered opinion of the interviewer that the six (6)
reports of 10 August and the attached report of 11 August can be explained
as the natura) phenomena of a shower of meteors from the vicinity of the
estar Perseids which reaches its maximum display at this time.

4. These reports of natural phenomena by army personnel who assume
they see unidentified aerial objects. bears out the necessity, as vrevicusly
recommended, for assignment of qualified technical personnel with special
equipment to carry out the mission of observing and recording unidentified

acrial phenomena,

SYNOPSIS

On 9 August 199, this District Office was teleohonically advised by the Federal
Bureau of Investigation (Sutte Office) of the pursorted sighting at 0930 A. w.,
that date, of eight (8) alleged "flying discs" in the Hebgen Lake, ‘est Yellow-
stone, Montana, area, Mr.
the informant, was contacted telenhonically and the essentials as previously
outlined by the Federal Bureau of Investigation was confirmed by this office,
Further information was forthcoming that two of the "flying discs" had
crashed in the immediate surrounding area. On August 10, ll, 12, 1919,
investization revealed that only one (1) individual actually saw the "flying
discs", a ir. "gO, employed as a "guide" by SM. A pro-
longed search was instituted for the two discs that crashed in the immediate
area with negative results. Interrogation of the only witness revealed him
to be indefinite as to the physical characteristics of "objects" sichted,
ditness further declined to make any signed sworn statement regarding the
sighting of the discs. Inquiries revealed Mr. “Ripa to have a
good reputation in all respects in the surrounding community, However, dis-
cussion with Mr, @MMMMll indicated to this AGENT that witness had a decided
tendency to exaggerate, Mr. Qe was informed by this AGENT that if he
found either of the tro "objects" which crashed, he was to immediately contact
the 15th OSI District (IG) USAF, Great Falls AFB, Montana,

Rape knew the avproximate location of both of the "discs" that had

objects. Mr, SBE stated that he believed that the eyewitness, a guide,
knew to within a few hundred feet the specific location of the "discs",
This AGENT questioned Mr, “MMMM closely, attemoting to eliminate all pos-
sibilities such as jet aircraft, radio-sonde devices, pilot balloons, rawind
devices, etc., with negative results. Mr. 49MM further asserted that

the objects were the approximate size and shape of an automobile tire, and at
the time of sighting were not flying in formation, ir, aaa stated that
they were definitely not balloons, having the appearance of being constructed
of metal and were grayish white, At the time of the sighing, Mr.
was standing on a boat siding at the edge of Hebgen Lake, the oojects came
across a ridge on the eastern shore of Hebgen Lake, just barely skimming the
top of the ridge, (This ridge is approximately 1500 feet higher than the
surrounding terrain) and were proceeding rapidly in a southwesterly direction,
Two of the objects in the first flight crashed, the one which crashed in the
lake threw up a large geyser of water, and the one which crashed in the woods
on the opposite shore (a distance of two miles from the point at which ‘Syme
was standing) raised a large cloud of dust as it hit into the woods. No fire,
explosion or smoke of any kind accompanied the crashes. The remaining five
objects disappeared rapidly from view across the ridges wnich are two miles
from the western shore of Hebgen Lake. Mr, QM could not estimate the speed
of the objects, however, he stated thet none of the objects were visible to
him for more than five to ten seconds, and the objects that crashed were visible
for about two (2) seconds, From maps of the general area this would place the
speeds of the objects at approximately fourteen hundred miles per hour, Xr,
AME stated that at the time of the appearance of the first seven objects,
there was no one in his immediate vicinity who actually saw them. ‘hen the
next one appeared, one-half hour later, he attempted to call the attention of
his assistant to them; however, it had disappeared before the Assistant could
view it. Mr.@@@M@llrurther stated that he had not intended to make an
official report of the sightings, but that when he told his employer, Qyp
Eee, Mir. “NM, took it upon himself to call the Federal Bureau of
Investigation relative to the matter,

5S. An attempt was made by this AGENT to contact other witnesses of the
same phenomena as reported by Mr. In this respect all employees
and guests of thesia Were interviewed with negative results, It
was learned that there was possinly one additional witness, a camper who had
camped on the shore of the lake overnight and had since moved on. In addition
to the employees and guests of the Lodge, attempts were made to find witnesses
among residents in the imnediate area, residents in the town of jest Yellowstone
(17 miles away) and from the U. S. Ranger Station, jest Yellowstone, Montana.
No witnesses were able to be obtained,

AGENT'S NOTE: There seemed to exist an apparent attempt by a number of individuals
to convince this AGENT that thea was absolutely reliable, trustwortity

and beyond question, that if he said this incident occurred, it did. The
statement was made by the euapumuair, Mr UMM that if anything was found,
the WP might become a "Mecca" for tourists, and it was this AGENT'S impression
that. whether anything was found or not, Mr. would have welcomed the
attendant publicity. Frequent conversations with the qgggamly Liv. .@aamyigiliivas

Clearly indicated that he had a decided tendency to exaggerate, and that
his conversation was often made up of grossly exaggerated stories,
