they attempt to manuever around them on file - which results with the
illusion or appearance that the ob,ject w moving around the aircraft -
instead of vice versa, This invariably ppens at very high altitudes
where there is o horizon, deturn or perspective points. Many reports
show that pilo stating that the object (balloon) was closing on on the
aircraft, wh ctually the balloon was standing still. This could
possibly account for r pilot's statement object circled around him. Correl-
ating this with his apparent, somewhat doubtful reliability in judging or
estimating size and distances (shown here) - this honest mistake or
belief on his part is understandable.
ADDITIONAL COMMENTS:

of controlled AIRWAY (AMBER) No. 1 - Running SE and NW,which carries
considerable traffic. Although the flight of the object pilot
observed closely parallels this traffic airway heading - which would
indicate the object was an aircraft - the characteristics, description,
flight pattern rule out aircraft, but strongly point out balloons.
On the basis of data given, analysis of the pilots information and his
personal reliability check, there is no compelling reason to conclude personal reliability check, there is no compelling reason to conclude
that the object observed was not probably a balloon.

UNIDENTIFIED FLYING OBJECT SUMMARY George T. Gregory
SUMMARY AND EXTRACT SHFET Capt., USAF
JFOB REPORT # 9-J-58
DATE OF INCINENT: 9 June 1958
LOCATION OF INCIDENT: NC-4320 (Position approx. midway TIME: 1817Z (1017 A.M. Local)
between Tacoma and Seattle, Washington
SUMMARY OF INCIDENT: Pilot of F-102 aircraft, while between 40,000 to 50,000 ft.
alt. at Mach. 9 (6oo+ MPH) observed a pinkish-white object, cylindrical in shape,
whose diameter was approximately l2 times.its depth (Comment: b believe Source
meant length). Pilot was going g South (18o ), when he observed object moving
due North which appeared to oscillate as it moved. Pilot made a left turn. Object
continued North. Then it appeared to (Note!) climb, slowdown, then do a left turn.
Pilot claims the object then circled his aircraft three times before he
descended to lower levels. !?
It is significant to point out (as a routine "source reliability" check or
clue), that pilot gave figures of 3/4 in: (diameter), 1/16 in. to 1/32 in. for
depth in estimates. Almost indredible that measurements like this could be given
while flying at 6oo MPH+. Hairbreadth measurements of this nature require
precision rulers, calipers or instruments. uiexs, ears
INVESTIGATIVE EFFORTS:
(1) Wind plots for area show winds from SE to NW for 40,ooo ft. (consistent
with flight path of object at estimated 40,ooo feet). with flight path of object at estimated 40,oo0 feet).
(2) Wind plots for area show winds from West to NE for 50,ooo ft alt and above
(consistent with pilots statement object made large turn at these estimated
altitudes).
(3) Balloon was Balloon was released about 20 minutes before sighting, and officially releesed sbout 2o minutes hefore and icially
reported to have reached at least 40,O00 by U.S. N. Wx Svs. in that area.
(4) Other pilits, radar units, others sin area did not see anything unusual.
Pilot states he did not make an effort to check if object was on his radar
PHYSICAL EVIDENCE: scope (?)
NONE
FINAL ATIC EVALUATION: PROBABLY BALLOON:
(1) Balloon released 20 minutes before sighting and up in that area.
(2) Up to est. 40,oo0 feet object on N. V-NW track. Wind was blowing in that
direction. At est. 50,ooo wind shifted, blowing from W-SW up to N-NE
(as showm by official check). This would account for change of
direction at that altitude (Object therefore was moving with wind,
generally).
(3) Pilot states object oscillated, slowed down, climbed, turned: these are
well-known, proven balloon characteristics.
(4) A word on pilots probable reliability (reporting officer did not evaluate):
note estimated measurements given in para. A.2 of report. Most observers
from fixed positions on ground cannot estimate within one or two inches.
