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
accepted as reliable and accurate. When psychological and physio-
logical factors are taken into consideration, all of these incidents
can be explained rationally, as pointed out by Rand Corporation and
The Fitts of Air Material Command Aero-Medical Laboratory (See

Incident No. 76 -- 13 August 1947, Salmon Dam, Idaho.

Two men reported simultaneously hearing a roar, and looking up observed two objects of undetermined size, several miles distant at a great height which they thought might have been 4000-6000 feet. The objects were "circular", "reflected light", and were traveling at "great speed". Although occurring on the same day as Incident No. 75, the descriptions vary widely.

AMC Opinion: There is no information contained in this report to refute the assumption that these men saw two ordinary aircraft at too great a distance to discern details.
