Incident No. 68 -- 24 June 1947, Daytime, Cascade Mountains, Washington.

A prospector reported sighting five or six round objects with tails, 1000 ft overhead, heading S.E., and banking in the sun. The objects were in sight 45-60 seconds, and alleged to be thirty feet in diameter. They made no noise. While the objects were within sight, the observers compass fluctuated wildly. He states that he read of a former sighting (incident No. 17) also occurring on 24 June 1947, and submitted this report solely to add credence to the person who provided that story. While there appears to be an attempt …

Incident #68 -- Portland, Oregon -- 24 June 1947

There is no astronomical explanation for this incident, which should be considered together with the Kenneth Arnold case (#17), which occurred on the same day, and in which similar discoid objects were observed. (The present objects appeared to have tails, however; another major difference between this and the Arnold incident is the inferred size of the objects, as determined from the estimated distance.)

It is difficult to take seriously the peculiar action of the compass, for this would imply fantastically large magnetic fields.

METHOD II. Direct use of Earth's Magnetic Field.

One observer (incident 66) noticed a violet motion of a hand-held compass. If we assume from this that the objects produced a magnetic field, comparable with the Earth's field, namely 0.1 gauss, and that the observer found that the object subtended an angle θ at his position, then the ampere-turns of the required electromagnet is given by

$$
ni = \frac{30 R}{\theta^2}
$$

where R is the range of the object.

For instance, if R is one kilometer and the object is 10 meters in diameter, then $ni \pm 1$ billion ampere-turns.

Now if the object wer…

While prospecting in the Mercede for June 3, 1929 it shows was found he noticed a reflection. When looking up he saw a Miss presenting in a comparatively discussion. When sighting it he showed his telescope to his eye and observed it for some 45 to 50 seconds. At the time the Miss was sighted it was looking in the sun. He observed 3 or 4 but concentrated no man. Held they did not fly to any particular direction and he estimated them to be about 1,000 ft from there he saw standing. He estimated that they were around 30 feet in diameter and that they had a tall. They made no noise. He noticed th…

With 194 incidents thus eliminated, there remain thirty-four
which contain some evidence but have no apparent ready explanation.
This statement is true only under the assumption that the evidence is
expected as reliable and accurate. When psychological and physio-
logical findings are taken into consideration, all of these incidents
are explained materially, as paints are by hand for
the use of Air Material Command Aero-Medical Laboratory (see
192 Incident considered)

There are sufficient psychological explanations for the
incidentified flying objects to provide plausible explanations for
rep…
