l. Introduction. To formulate tho possible tactic• of

sions have beon reached on both the exiotonce pnd origin of the r oported
flying objects. The current status of information on such incidents
and overall analys1o doec not cllow subotentiation for auoh concluaione.
However. the lack of such firm concluaions points to the necessity for
an immodiato and sound statisticnl annl7oiA of every nepect of the aituo.
tion and doeo not proclude a concurrent examination of the reported in
cidents to develop explanatione of their possible tactioe. The latter
will be useful at oome future date ohould tho exictencea.ndoririn of the
flying objocts be definitely e•tabliahed. Theroforc , tho followint;
anolyais of availablo information ii advanced in order to praeent evi
dence on the actunl exhtenoa of somo tn,e fl7ill(; object and to relate
samo to tactical purposen for which the objects are pose1bly deeiEned.

Silver disks or balls have, or the greater part, been observed in

A few accounts toll of ·eks havil'.l,f; u rough eigar- ahapo whon

out the 1t'ostern Coast states, and a . few sightiru?s

Distribution of incidonts by configuration of object snd description
of maneuverability is approximately equal in each of theoo araaa and
this i o believed to further 's ubstanti ate the possibility tbet one type

completion of annlyaeB, it 1c inrlicated that nome or nll of the reported

from a logical viewpoint, be couaidered Soviet. It is evident from the
perforaance character1et1oe attributed to the un1dnntified objectn at
thiu time that 1f they are foreign, the1 involve efficiencies of por
formanoe which hnve not been ro&liz•d in nn~ op~rat1ollt\l airborne de

technical n,weets of the situation within th• limtt, of our cwn knowl

the 0\1ter llmiti, of poealble Soviet develop11entfl and objecti1.ve11 in nt•

of all, the objectiveG of ihe u.s.s.R. ha.ve
- been st tod many times and indicatod i n many f orms, The most clear
cut statement of this obJoctive is prob bl7 the one contained in the
prea ble to the ourth five- year Plan (1946-1950) which states that
the objective of Soviet science ie to overt ke and surp an the seienti-
.fio and technical development ,of the ca 1tali t nat1ona~ It appar ntly
.would be · n imnosoible tosk for the Goviet Union to ocoopliah such an
.objoctive by proce ding st~- by- atep lone; the same lines of develop
ment already achieved in the capitalist tione. This would menn that
it would b-e ne oossary to rapidly proceed through en.ch phase of aero-
n utic I development that bae lr aa,- been accomplished in thia country, and
this ~robably would never have any pro pecto of ace ler ti Soviet dev lop
ment b yond any point re ched by the U. S. Th obviou an wer to coom

objects first appeared over he Scandinavian coUhtriee in 1946. The ob-
jects observed there had unu ual range and unusual performance oharacteris-

tho U. S. was making a v1goro s campaign for t he economic and political

foilure to i dent ify such a object would give them inval uable in

not been made over what we consider strategic industrial arooe . The
reason for thia mi~ht be either thnt the flying_objecto have boen ob

during thoir World War II liaioon with u.s. industry to natiafy tho1r

5. Concluaioa. !he conclusion thot some tYPe of flying object
has been observed ovor the U.S. seems to be substantiated. It is not
known at this time whether these obae:r"V'at1ono are mioidontifieations
of do~estically launched devices, natural phenomenn, or foreien un
conventional aircraft. It is, therefore, i mpossible to noke any re
