10, BRIEF SUMMARY OF SIGHTING Round white objt size of |1). COMMENTSReport contains very little

pea. Appeared 45° elev, 160° az. Disappeared jinfo, but what there is give no reason to

75° elev, 200° az. Larger than stars.

ATIC FORM 329 (REV 26 SEP 52)

believe that objt was anything other than
a/c which was in area. Absence of unknowns

reported by radar units in area support
this conclusion. There are many possible
situations where movement of a/c could be
mistaken by ground observers to be for
example right angle turns; it all depends
upon what plane the a/c is maneuvering in
and its xkxk relationship to observer.

BEEN CAUSED BY AN F-192 DOING EXTENSIVE FLYING AND MANEUVERS IN THE
LOCAL AREA WITH AFTER-BURNER. THERE WERE NO MISSILE FIRINGS OR : e*
AERIAL TESTS IN THE AREA. A STRONG POSSIBLITY EXIST THAT A DIS

BOTH OBSERVERS SAW AN OBJECT LARGER THAN THE STARS, MOVING TOWARD

TO MAKE SHARP FAST MOVEMENTS SIDE TO SIDE AND VERTICALLY CONTINU
ING.-IN GENERALLY THE SAME DIRECTION. THE OBJECT THEN STOPPED,
HOVERED FOR A FEW YECONDS, THEN BEGAN TO MOVE IN A WIDE GRADUAL TURN
AND PROCEED SOUTH. AT ZS POINT THE OBJECT WAS LARGER THAN THE:
