As the machine went by the place, the trees over which it almost directly passed (Morman Poplars) did not just bend with the wind as if a plane had gone by, but in words, "spun around on top as if they were in a vacuum."

eight years of age, said he first saw the machine coming down the canyon, heading from east to west and following the contours of the ground, age ten, saw it almost immediately. Both watched it fly out of sight behind a tree in a matter of moments. They said they then ran to their Father and learned that he too had seen the machine.

had sent his sons to the river for some tops from his boat. As they were overdue he went to look for them, when he noticed some 300 feet away some 75 feet in the air a sky-blue object silhouetted against the steep walls of the canyon on the far side. (The canyon is about 400 ft deep and 1200 ft across at that place.) The object was traveling 75 feet in the air (300 ft below the rim of the canyon) and so was plainly visible. states that the sky-blue color would probably not be noticed against the sky. He states that "it did not spin like a top". However, he did say that the trees over w…

With 134 incidents thus eliminated, there remain thirty-four

This statement is true only under the assumption that the evidence is
accepted as reliable and accurate. When psychological and physiological
factors are taken into consideration, all of these incidents
can be explained rationally, as pointed out by Rand Corporation and

Incident No. 75 -- 13 August 1947, 1300 hours, Smoke River Canyon, Idaho.

A farmer together with his two sons, ten and eight years of age, witnessed an object move down a canyon. It was in view only momentarily at a distance of 300 feet, and approximately 75 feet above the ground. The object made a swishing sound, and was sky-blue in color. The farmer doubted the possibility of its visibility if viewed against the sky. The children told of smokeless turbine or exhaust flames shooting from the device through which could be seen daylight. The object passed over some trees, which in the words of…

Incident #75 -- near Twin Falls, Idaho -- 13 August 1947

There is clearly nothing astronomical in this incident. Apparently it must be classed with the other bona fide disc sightings.

Two points stand out, however: the "sky blue" color, and the fact that the trees "spun around on top as if they were in a vacuum." Could this, then, have been a rapidly travelling atmospheric eddy?
