This left 56 per cent still unknown. By weeding out the hoaxes, the reports that were too nebulous to evaluate, and reports that could well be misidentified airplanes. Project Grudge disposed of another 33 per cent of the reports. This left 23 per cent that fell in the “unknown” category.
There were more appendixes. The Rand Corporation, one of the most unpublicized yet highly competent contractors to the Air Force, looked over the reports and made the statement, “We have found nothing which would seriously controvert simple rational explanations of the various phenomena in terms of balloons, conventional aircraft, planets, meteors, bits of paper, optical illusions, practical jokers, psychopathological reporters, and the like.” But Rand’s comment didn’t help a great deal because they didn’t come up with any solutions to any of the 23 per cent unknown.
The Psychology Branch of the Air Force’s Aeromedical Laboratory took a pass at the psychological angles. They said, “there are sufficient psychological explanations for the reports of unidentified objects to provide plausible explanations for reports not otherwise explainable.” They pointed out that some people have “spots in front of their eyes” due to minute solid particles that float about in the fluids of the eye and cast shadows on the retina. Then they pointed out that some people are just plain nuts. Many people who read the Grudge Report took these two points to mean that all UFO observers either had spots in front of their eyes or were nuts. They broke the reports down statistically. The people who wrote the report found that over 70 per cent of the people making sightings reported a light-colored object. (This I doubt, but that’s what his report said.) They said a big point of . these reports of light-colored objects was that any high-flying object will appear to be dark against the sky. For this reason the UFO’s couldn’t be real.
I suggest that the next time you are outdoors and see a bomber go over at high altitude you look at it closely. Unless it’s painted a dark color it won’t look dark.
The U.S. Weather Bureau wrote an extremely comprehensive and interesting report on all types of lightning. It was included in the Grudge Report but contained a note: “None of the recorded incidents appear to have been lightning.”
