Analysis ot "Utah" Film
That the air turbulence necessary to account tor their movement if' they
were nearby inspects (even the single obJect's motion!) is possible, can be
concluded. trom examination of reference (8). However, if the objects were
nearby spider vebs the lack ot observed or photographed streamers is unusual.
Furthermore, the f'aet that they were visible from a moving car for several
minutes is hard to reconcile with localized insect activity.
The phenomenon of atmospheric mirages, reference (9), might conceivabJ.¥
account tor the images.
Such a hypothesis is hampered by the clear weather
conditions and the persistence and clarity of the images.
Also no "shi.Jmler­
ing" can be detected end the motion is steady.
Again the object which breaks
awec, would be dif'f'icult to explain.
It has been suggested that spurious optical ref'lect·1ons or light leaks
in the camera might be responsible.
Examples of' such effects have been ex­
amined and found to be quite different from the UFO's.
The evidence remains rather contradictory and no si:cgle hypothesis of a
natural phenomenon yet suggested seems to completely account for the UFO
involved.
The possibility of multiple hypotheses, i.e. that the utah UFO's
ere the result of two simultaneous natural phenomena might possibzy yield
the answer.
However, as in the case of the "Montana" analysis, no definite
conclusion could be obtained.
