(Unclassified) Unidentified Flying Objects Reporting (Short Title: FLYOBRPT

  1. Purpose and Scope.  This Letter sets forth Air Force responsibility 
and reporting procedures for information and materiel pertaining to 
unidentified flying objects.  All incidents observed by Air Force 
personnel or received at any Air Force installation from a civilian 
source will be reported in accordance with this Letter, except that 
all airborne sightings by Air Force personnel, Civilian Air Patrol, 
and regularly scheduled United States airline pilots will also be 
reported as provided by JANAP 146 series (CIRVIS).
  2. Definition.  Unidentified flying objects, as used in this Letter, 
relates to any airborne object which by performance, aerodynamic
characteristics, or unusual features, does not conform to any presently 
known aircraft or missile type.
  3. Background.  The Air Force has been conducting a continuous 
analysis of all reports of unidentified flying objects for the past 
several years.  Analysis of these reports has neither proved nor 
disproved the possibility of the existence of such objects.  The 
possibility of future development of some type of flying object, 
unconventional by present standards, dictates a continuing need for 
reports of observations.
  4. Guidance.  Theodolite measurements of changes of azimuth and 
elevation and angular size are of great aid to the evaluation of reports.
Interception, identification, and air search action may develop additional
information important for evaluation purposes.  These actions may be taken
if appropriate and within the scope of existing air defense regulations.
  5. Responsibility:
      a. Analysis.  The Air Technical Intelligence Center (ATIC), Wright-
Patterson Air Force Base, Ohio, has been designated the Air force activity 
responsible for conducting analysis of all information and material 
      b. Cooperation.  All Air Force activities will assist ATIC in the 

development of pertinent investigations, including the furnishing if air 
and ground transportation, as may be requested by ATIC representatives and 
when feasible.  Direct communication between ATIC and zone of interior 
activities is authorized when essential due to time and economic factors.
      c. Reporting.  Installation commanders are responsible for insuring 
that reports are initiated.
  6. Material Evidence.  In the event any actual or suspected items of 
material pertinent to any unidentified flying object incident comes into 
the possession of any Air Force echelon, two actions will be taken without 
      a. Safeguard the material carefully to prevent any defacing or 
alteration which would reduce its value for technical analysis.
      b. Notify ATIC immediately and request shipping instructions or 
other special instructions as may be appropriate.
  7. Reports.  Information relating to unidentified flying objects will be 
reported without delay.  Originators will select the priority appropriate 
for each incident in accordance with its apparent importance as 
intelligence. Reports will be concerned with a single incident.  Reports 
will be forwarded immediately by electrical means and confirmed and 
elaborated upon by a written report within three days.
      a. The symbol FLYOBRPT will appear at the beginning of the text of 
electrical messages and will be used as subject of written reports to 
facilitate identification.
       b. Security.  Reports should not be classified higher than 
"Restricted" unless inclusion of data required by c and d below mandates 
a higher classification.  Local publicity concerning this reporting and 
analysis activity is to be avoided.
      c. Electrical Means. Reports forwarded by this method will include, 
insofar as possible:
        (1)  A Brief description of the object(s); shape, size, color, 
number, formation if more than one, aerodynamic features, trail or exhaust,
propulsion system, speed, sound, maneuvers, manner of disappearance, and 
other pertinent or unusual features.
        (2)  Time of sighting in 24-hour clock zonal time, and length of 
time observed.
        (3)  Manner of observation; visual or electronic, from air (give 
speed, altitude, and type of aircraft), or surface.  Any type of optical 
or electronic equipment used should be described.
        (4)  Location of observer during sighting, given exact latitude 
and longitude as closely as feasible, and/or reference to a known landmark.
Location of object(s) with respect to observer, giving distance, direction,
and altitude.
        (5)  Identifying information of observer(s) and witness(es), 
estimate of reliability and experience, and any factors bearing on 
estimated reliability of the sighting.
        (6)  Weather and winds aloft conditions at time and place of 
        (7)  Any activity or condition, meteorological or otherwise, 
which might account for the sighting.
        (8)  Existence of any physical evidence such as fragments, 
photographs and the like, of the sighting.
        (9)  Interception and identification action taken.  (Such 
action may be taken whenever feasible, complying with existing air 
defense directives.)
       (10) Location of any air traffic in the general area at the time 
of the sighting.
      d. Written Reports.  These reports will be submitted on AF Form 112,
"Air Intelligence Information report," and will expand on the points 
enumerated in c above.  photographs, sketches, and signed narrative 
statements of observers will be appended.  Statements should be recorded 
in as great detail as possible, with particular attention given to times, 
angles of observations, locations, flight paths, etc., should be drawn 
on aeronautical charts or maps.
      e. Channels:
        (1) Electrical reports will be dispatched in multiple address 
             (a) Director of Intelligence, Headquarters USAF, Washington 
25, D.C.
             (b) Air Technical Intelligence Center (ATIC), Wright-Patterson
Air Force Base, Ohio, ATTN: ATIAA-2c1
             (c) Commanding General, Ent AFB, Colorado Springs, Colorado
             (d) Appropriate major air command headquarters
        (2) Written reports will be submitted through channels to:
              (a) Director of Intelligence, Headquarters USAF, Washington 
25, D.C. for ozalid-type reproduction and dissemination.
              (b) Chief,  Air Technical Intelligence Center, ATTN: 
ATIAA-2c, Wright-Patterson Air Force Base, Ohio, one copy for information.
