“These abnormal aspects included the shapes of UFOs and their behavior. Most of the UFOs seen in the daytime were said to have had simple geometric shapes-discs, ovals, spheres, cylinders-and surfaces that looked like metal. Such shapes are not only nonexistent among known aircraft, but contrary to all known theories of flight, in most cases offering control and performance disadvantages rather than advantages.” SaidSimpleKnownCasesTheoryShapesBehaviorAdvantageAspectPerformancesSurfaceContraryFlightSpheresMetalsOfferingUfoDisadvantagesAbnormalAircraftDaytimeDiscsOvalGeometricCylindersGeometric Shapes Author:Don Berliner
“For more than 50 years, men and women around the world have reported sights in the sky that are strange to their experience and understanding. Inasmuch as many of these sights appeared to be solid objects having impressive performance, they have become known as Unidentified Flying Objects (UFOs) or, colloquially, flying saucers. Their positive identification is one of the major public scientific challenges of the era, with a significant number of these sights so far defying all reasonable efforts at classification.” MenWorldYearsUnderstandingChallengesNumbersEffortKnownSkyObjectsStrangeMajorsMen And WomenPerformancesSightFlyingSignificantAround The WorldErasReasonableImpressiveUfoIdentificationClassificationDefyingFlying SaucersSignificant Numbers Author:Don Berliner
