ing high overhead after 8 hours of continuous observation. It appeared low on
the Eastern horizon, much brighter than the surrounding stars. It was reported
to hover an n move at terrific speeds by several local inhabitants, includ-
.ing several county sherif Ground'Observer Corps members. Two of the police
men pursued the object in without gaining any noticeable ground.
A telescope was employed to phenomenon by the GOC members. The weather
during the time of sighting was unusually clear with a few scattered clouds
carried on a north heading by the wind.
II. DISCUSSION
A newspaper account of the sighting came to the attention of ATIC and as a
result an officer and an astronomer were sent to the area the sighting. They
variety of reports. Estimates of azimuth and elevation readings were obtained
from different observers at varied locations in Monroe and Darlington for .
evenly spaced time intervals during the 8 hour period. he description of the
object turned out to be the same with all observers bright white The des-
cription of the maneuvers varied, however, some stating the object r rose slowly,
others saying it moved at great speeds, and then hovered. The latter description
usually came from observers while riding in a car. usually came from observers while riding in a car. All agreed that the object All agreed that the object
was too bright to be a sta reover it was seen in the daytime.
It was determined that the path of the object in question across the esky,
its position appearance and disappearance, very closely paralleled the path
of the plane on 31 May 1953. Venus on this day rose at O3lo CST and was
at its approximate maximum brilliancy. Under ideal weather conditions it can be
seen in the daytime, although this is rare. The fact that Goc personnel first
sighted it at night and had the object pin-pointed for daylight observation al-
lowed them to keep it under constant surveillance. Reports that man-
euvered radically usually from persons driving in cars whil observing the
object. If Venus is stared at for any length of time without any balancing ref-
GOC personnel alerted the Chicago filter center and jets were scrambled to
investigate. This was during daylight observation and the jets, although vec-
tored toward the object by visual directions from Darlington, were unable to locate
the unknown.

The airway station will normally answer on the radio range or radiobeacon frequency. If reply is desired on other than the
radio range or radiobeacon frequency, pilots should indicate the frequency on which the station reply is expected.
Example: "CLEVELAND RADIO - THIS IS - STIN ISON ONE THREE SIX FIVE - REPLY ON ONE ELEVEN
POINT ONE MEGACYCLES - OVER".
After the airway station has answered your call, proceed with your message without further call up other than preceding the
message with the aircraft identification. Your message may consist of y your position
other information that may be required to assist you to your destination.
Example: "STINSON ONE THREE SIX FIVE - OVER CLEVELAND AT ELEVEN TWENTY - FOUR THOU-
SAND FEET ON VFR FLIGHT PLAN FROM YOUNGS THE WEA-
THER AT TOLEDO - OVER".
If you are f flying VFR, a position report is not required, however, it is to your advantage that the stations along your route
of flight know your position at all timnes in order that assistance can be rendered should you encounter difficulty.

The word "ROGER" is used to acknowledge receipt of a message.
The word "OUT" is used when a conversation is ended and no response is expected.
Example: Example: STINSON ONE THREE SIX FIVE - R STINSON ONE THREE SIX FIVE - ROGER, OUT". GER. OUT".
The words "SAY AGAIN" are used if a message was not understood and a repetition is desired.
The words "STAND BY" are used to indicate that a return call will be made as soon as practicable.
Examples: "STINSON ONE THREE SIX FIVE - SAY AGAIN, OVER".
"STINSON ONE THREE SIX FIVE -STAND BY". STINSON ONE THREE SIX FIVE -STAND BY".

V.H.F. OM
The V.H.F. omni-range operates within the1 112-118 megacycle band. In this band it is relatively free from atmospherie and
precipitation static and interference from other radio stations. Furthermore, it is not limited t to four courses as is the A-N
range, but provides definite guidance on any course, to or from the station, the pilot may select. That is why it is called the
Omni (Directional) Range. At minimum instrument altitudes the VOR gives reliable indications up to about 50 miles, depend-
ing on enroute terrain.
In flying the V. H. F. omni-range, the pilot uses three basic instruments. The first is the Flight Path Deviation Indicator (cross-
pointer instrument), the same type used for the visual-aural range (VAR) and the ILS localizer. The vertical needle of this in-
strument tells s the pilot whether he is right or left of the desired course. The second is an Omni-bearing Selector, manually oper-
ated by t the rotation n of a small knob, by which the pilot selects the course he desires to fly. When the cross-pointer needle is
centered, the omni-bearing selector indicates the magnetic bearing of the aircraft either to or from the station. The third is a
"TO-FROM" indicator which shows whether the bearing indicated by the Omni-bearing Selector is from or to the station.
Furthermore, the "TO-FROM" needle can tell a flier when his aircraft is too far from the VOR or is others ise receiving a weak
sector instead of TO or FROM,
In operation, the pilot selects a course by adjusting the omni-bearing selector to the desired magnetic bearing, and then main.
tains it by keeping the cross-pointer needle centered. If the aircraft is correctly aligned with the TO-FR cations, when
the needle swings to the right, for example, it indicates that the course selected lies to the right.
N For example, an aircraft is due south of a VOR station. If its pilot desires to fly to the station, he sets the omni-bearing selector
to indicate 0°. The "TO-FROM" indicator will then point to the word "TO". As the aircraft passes over t the station the
"TO-FROM" indicator will point to the word "FROM". If a turn of 180° is made north of the station, although the vertical
or cross-pointer needle will again become centered, the "TO-FROM" indicator will still point to "FRC M". The pilot, however,
will now find that he must fly "Away from the needle" to stay on course. This shows him that the "'TO-FROM" indieator is
incorrect. So, the pilot now rotates his omni-bearing selector to 18o. After he has done this, the "TO-FROM" indicator shifts
3A to the "TO" position, and flying "Toward the needle" will keep him on course.

All continuously operated CAA radio range and radio beacon stations h having voice facilities on the range or radio beacon fre-
quencies broadeast weather reports and airway information at 15 and 45 minutes past each hour. The 15-minutes past-the-
hour broadcast is an "airway" broadcast consisting of weather reports from important terminals located on airway (s) within
approximately 400 miles of the station. The 45-minutes-past-the-hour broadcast is an "area" broadcast consisting of weather
reports from locations within the flight information area of the station.
The broadcast consists of the local weather report and the latest available surface reports from other locations. Reports more
than one hour old are not broadcast. Local winds aloft are broadeast 4 times after the broadeasts 5 A.M., and
P.M., E.S.T. The velocities of winds aloft are broadcast in knots - not miles.
At selected stations the Weather Bureau provides a local terminal forecast covering the next two 'his forecast is broad-
cast, when available, immediately following the local weather report.
Pilots enroute are requested to avoid, if possible, calling airway communications stations at or about 15 and 45 minutes past
the hour (which are the scheduled broadcast times) to request weather information, as such calls may delay starting of
scheduled broadcasts and cause inconvenience to other persons who are pendent on the broadcasts for weather reports.

VISUAL FLIGHT PLANS
The Civil Air Regulations do not require that a VFR flight plan be filed for a VFR flight. However, the filing of such a flight
plan is desirable, and the CAA urges that VFR flights be covered by flight plan whenever practicable as such filing materially
assists in search and rescue operations if such action becomes necessary. Flight plans may be submitted to the nearest CAA
airway communications station either on or by telephone. Flight plans may be filed by radio if no other means are
available but this practice should be avoided whenever e to reduce congestion of radio channels.
If filing the flight plan, the pilot should state the name of the CAA communications station with which he will close his flight
plan. If the destination is not served by a CAA communications station, or is in Canada or Mexico, the method by which the
arrival report will be filed must be clearly understood by all concerned. VFR flight plans are transmitted via CAA communicx-
tions facilities only to the CAA communications station with which the pilot has stated his arrival report or closing of
E flight plan will be filed. One hour after the estimated time of arrival, if no notice of arrival is received, queries are sent out over
CAA cornmunications systems to determine the location of the aircraft. If no information concerning the aireraft is obtained
after an exhaustive communications inquiry, search and rescue operations are inaugurated. In as much as the government
may be put to considerable expense ind determining g the location of aircraft when an arrival report is not filed, it is vitaily
necessary that all pilots make certain that notice of a arrival is filed. If flight is terminated prior to reaching the point of intend-
ed destination specified in the flight plan, pilots should contact the nearest CAA commnunications station and the request that
an arrival report be transmitted over CAA facilities to the CAA communications station with which the pilot stated the arrival
report would be filed.
Pilots of aircraft operating on VFR flight plan who desire to make flight progres , should include in the report the
(blank)."
The flight plan shall contain the items listed under INSTRUMENT FLIGHT RULES - Flight Plan, except "Alternate
Airport" and except that a visual flight rule flight plan should always specify "VFR" as a cruising altitude. The use of this
term in lieu of an actual altitude indicates that the pilot intends to fly in aceordance with Visual Flight Rules. Aircraft may
be operated in accordance with VFR above a well defined cloud or r other formation provided, climb to and descent from such
"on top" flight can also be made in aceordance with VFR.

be added for a temperature of 1oo° and pressure

temperature sea level take-off distance, in order to

LOSS OF AIRCRAFT PERFORMANCE DURING HOT WEATHER
Thin Air Reduces Lift. You get thin air at high altitudes and in hot weather. hotter the temperature, the thinner the
nir.
Do you realize that Kansas City Airport with an elevation of 744 feet above sea level can have an effective elevation identical
to Stapleton Field, Denver, at 5325 feet above sea level, under conditions of extreme heat and low pressure?
titude of your aircraft during hot weather?
Note: The effective elevation of Brees Airport at 86°F, for example, is 10,250 feet-Caution!
The rarified air at higher altitudes lowers the efficiency of engine and propeller, and lessens a plane's rate of climb. A typical
light plane has a maximum rate of climb at sea level of 420 feet per minute, whereas its maximum rate of climb at 5,000 feet
altitude is only 225 feet per minute.
This plane might be able to clear a 400 foot hill or factory stack located a few miles from a sea level

A syn
this:
Between 3:20 A.M. and 11:30 A.M. on 31 May eleven persons
in the Darlington-Monroe area in Wisconsin sighted an unidentified
aerial object. The object appeared as a steady white light coming
generally out of the east and disappearing high overhead after oight
hours of observation. It was reported to hover and then attain
torrific speeds several local inhabitants including several coun-
ty sheriffs and Ground Cbserver Corps members Two policemen pur-
sued the object in their at 70 mph and said that the object

Police dispatchers in Monroe alarted the local COc post

paralleled the path of the planet Venus. Venus 3 on 31 May 1953 is
near its maximum billiancy and under idaal weather conditions can
be seen in the daytime, although this is rare. Usually only trained
obs ervers can detect 1t. If Venus is stared at for any longth of
time, it will appear to man euv er erratically and attain great
speeds, all these characteristics having been attributed to the
unknown object sighted lington.
General Outlook on Project Bl
Since 1947 3,000 reports of unidentified aerial objects have
been turned in to the Air Force. In 1952 alone 1700 reports were
recorded. The Air Technical Intelligence Center objectively ex
amines each report and feels that it can explain 80 to 90% as known
phenomena or marmade objects. There is, however, the remaining
15% which cannot be explained to the Air Force's satisfaction.
Some of these are truly perplexing, these are truly perplexing reports from highly from highly credible
people, others are so sketchy that they aren't worth scientific orth scientific
investigation.
Some of the phenomena which Some of the phenomena which have caused "flying s have caused "flying saucer" saucer" re- re-

however, majority of them caused by frequency intereference,
temperature or dew I point inversions, and thumderstorms. The best
type of sighting ATIC receives as far as instrumentation scienti-
fic data is conc erned are combination visual an adar detections.
The Air Force does not pretend to be able excplain all "flying
saucer" reports but it does feel that it knows enough about the
entire subject to say that there is no exdsting danger to the United
States nor is there anything to cause undue speculation or hysteria
Of all sightings 80 or 90% have been explained. The Air Force be-
lieves that it has the responsibility of assuring itself and the
public with as I much conclusiveness as possible on a sometimes
nebulous subject, that nothing unforeseen is going on in our skies
After reviewing 3,000 reports ATIC and general scientific opinion
which it has consulted find that there is absolutely no proof that
space travel from another planet is going on.
