“Barring hallucination, these two incidents and 17, 75 and 84 seem the most tangible from the standpoint of description, of all those reported, and the most difficult to explain away as sheer nonsense.” Case 17, I found, was that of Kenneth Arnold. But in spite of the above admission that this case cannot be explained away, it is officially listed as answered. Case 75 struck a familiar note. This was the strange occurrence at Twin Falls, Idaho, on which _True_ had had a tip months before. A disk moving through a canyon at tremendous speed had whipped the treetops as if by a violent hurricane. The report was brief, but one sentence stood out with a startling effect: “Twin Falls, Idaho, August 13, 1847,” the report began. “There is clearly nothing astronomical in this incident. . . . Two points stand out, the sky-blue color, and the fact that the trees ‘spun around on top as if they were in a vacuum.’” Then came the sentence that made me sit up in my chair. “Apparently it must be classed with the other bona fide disk sightings.” _The other bona fide sightings!_ Was this a slip? Or had the Air Force deliberately left this report in the file? If they had, what was back of it—what was back of releasing all of these telltale case summaries? I skimmed through the rest as quickly as possible looking for other clues. Here are a few of the things that. caught my eye: Case 10. United Airlines report . . . despite conjectures, no logical explanation seems possible. . . . Case 122. Holloman Air Force Base, April 6, 1948. [This was the Commander McLaughlin White Sands report.] No logical explanation. . . . Case 124. North Atlantic, April 18, 1948 . . . radar sighting . . . no astronomical explanation. . . . Case 127. Yugoslav-Greek frontier, May 7, 1948 . . . information too limited. . . . Case 168. Arnheim, The Hague, July 20, 1948 . . . object seen four times . . . had two decks and no wings . . . very high speed comparable to a V-2. . . . Case 183. Japan, October 15, 1948. Radar experts should determine acceleration rates. . . . Case 188. Goose Bay, Labrador, October 29, 1948. Not astronomical . . . picked up by radar . . . radar experts should evaluate the sightings . . . . Case 189. Goose Bay, Labrador, October 31, 1948 . . . not astronomical . . . observed on radarscope. . . . Case 196. Radarscope observation . . . object traveling directly into the wind. . . . Case 198. Radar blimp moving at high speed and continuously changing direction. . . . Case 222.
