It includes Portland police officers' accounts of a silvery object over the city on September 11, 1947, an Alaska pilot's July 1947 sighting near Bethel, citizen letters answered by J. Edgar Hoover, and a 1948 Air Defense Command directive on disc investigations. The FBI replied that it was conducting no flying disc investigations. Later items concern William Albert Rhodes's disc photographs and a Los Angeles letter judged a probable prank.

vapor trail being left by an aircraft moving at extreme~ high speeds or extremely
high altitudes, the vapor trail usually will be from the wing tips and/or the
exhau~t of the engines, thus presenting several lines. But, in any event, even
~ouslj onJJ, one line were visible, it would be ~ther quick to dissipate. This
indif1ted to him that the vapor trail represents some atmospheric change along
t he :path or the missile, which voul.d not be the case were it any presently known

not deemed it advisable to advise him of all information pertaining to the missile.
He continued, however, that in his conversation w1th representatives at Wright
Field and in re&d.ing reports returned to this country by f'ore1gn agents, he had
gathered together certain information which might be of assistance in determining
whether or not these so-called missiles were authen:tf.o, usable and of claxJser to
the United Statee. First, he pointed out that knowledge o£ such a possible
aircraft is not by aey meaDS new, it having been known as early as four years
ago that same type of flying disc was be1ns experimented with by the Russians.
In addition thereto, he stated that more recent reports have been received
from representatives of the Central Intell.igence Agency in Southern Europe and
Southern Asia to the effect that the Russians were experimenting with some type
of radical aircraft or guided missile which could be dispatched for great dis
tances out over the sea, mde to turn in flight and return to the base from which
it was launched. Thie fact was extremely worthy of notice as experiments in
this country have so far only developed to the point where we are concerned with
deliverine a missile to the required point of impact, and no consideration has
been given to imparting to that missile the ability to return. Seconcll.y, he
stated that it is a known fact that the Russians are attempting to develop
some type of nuclear energy, that they received a wealth of information concern
ing nuclear energy at the time of their occupation in Ge.rmany, and that they too
have at their dispoeal the limited supply of the necessary fissionable materials.
He stated that insofar as aey opinion as j;o hether or not they have the ability
and scientific lmowledge to create such • u - o elled missile is etrictl.J'
a matter o£ conjecture, and that he wou esitate o nite statement.
He pointed out, however, that the Russians have acme very capable scientists in
the field of atomic energy and that, in addition thereto, they took into their
custoc:'cy sane of the most advanced and capable scientists of the Ge:r,mn Nation.
Re also etated that a peculiar fact concerning the missiles exists
from reports he has received which is worthy of notice, and that is that from
all appearances, they usually approach the United States from a northerly direc
tion and have been reported as returning in a norther.cy direction. None have
ever been lmown to crash, coll.ide or disintegrate over American soil, but it
woul.d appear that they come to the United States, cruise around, and go back
over the North Pole. He states that insofar as is known to him, there has never
