An official the meteorological station said that it meteor-

of meteorites breaking up in flight and leaving no trace. Meteorites vary in size and the
larger variety, often as big in diameter as a table radius of
fifty miles. Other sources claim it was a comet but the general opinion seems to accept
that the explosion fact caused fiarly substantial size.

holder was used. These cameras have maximum shutter speed 1/1000 of a
second. The depth of field this photograph extends from the vegetation in
the foreground to the mountains in the background. Therefore, any object
between these two points would be focused critically The blurred
area of the negative, reported to be an unidentified aircraft, is focused
as critically by the lens. For the blurred area to be formed by the lens, the
object would have t closer to the camer vegetation in n the foreground.
3. states that the object shiny attracted the attention
of the observer, thereby indicating that the object was brighter than the
surrounding sky area. The report also states that the underside of the aircraft
was in shadow. From these conditions the image should be of greater density at

no indication of greater density unidentical than that of

4. The photographic technique displayed by this negative The
negative is light struck or fogged by extraneous light probably was caused by
light leaks in the camera or cut film holder. (Exhibit l, arrow 1) At the
end of the negative opposite the coding notches edge of the film which is
covered by the holding edge of cutfilm holder is fogged indicating the
film was fogged during processing or was out of date. (Exhibit 1, arrow 2)
The surface of the nega ative is pock-marked with numerous blemishes which may
have been caused by contaminated processing baths or higher than recommended
processing temperatures. (Exhibit 1, arrow 3) The image may ha ve been caused
by foreign material in the developing solution which adhered to the surface
of the film and locally retarding development. Such foreign material may have
been a piece of paper ma filmpack.

sible to confirm this negative as being a photograph of an unconventional
of aircraft nor is it posible to confirm that the image on the negative
was formed photographically by ‘the camera. It is wnfortunate that the m jority
of exhibits sutmitted as being photographs of unconvention type of aircraft are

of such notably poor quality that they offer practically no basis for technical
