AF FORM 112-PART I (Report No. AIR No. WIN 2-52, from 435th Troop Carrier Wing (M); prepared by John H. Sharpe, Major, USAF; date of report 16 April 1952; date of information 5 April 1952; evaluation C3; source: Civilian Observer) -- Full narrative of the sighting. Observer identified in the report as Mr. Van Derear (name appears in text and sketch attribution). Intelligence assessment by 435th Wing Intelligence Officer is included. 3. AF FORM 112-PART II (continuation) -- Includes the Wing Intelligence Officer's full assessment of Mr. Van Derear's credibility and character, and the absence of corroborating witnesses. 4. OBSERVER SKETCH (1 Incl.) -- Free-hand sketch attributed to Mr. Van Derear depicting the moon (large circle) with a dark circular object partially overlapping its face. Labeled "FADE OUT AT EDGE" with arrow indicating the object's trailing corona. Direction arrow marked "E" (East) with time notation 2115. File/form reference number F437285 appears on sketch. 5. NOTE ON BUNDLED KOREA DOCUMENTS: This PDF also contains Air Intelligence Information Report IR-131-52 from 66 Bm Sq Intelligence, 44 Bm Wing, LGAFB, Louisiana -- a debriefing of Korean combat crew returnees covering Nov 1951 to Apr 1952, approved by Lt Col Theodore I. Pascoe, Director of Intelligence. This report concerns entirely separate observations at Naha AFB and Kadena AFB, Okinawa (5 April 1952, approximately 2400 hours), and has no connection to the Miami case. It appears bundled in this file, likely due to the shared date. The Kadena observations (five elliptical objects at estimated 1000 knots, and a separate maneuvering light observed over the base for ten minutes) are not analyzed here and would merit their own eval under a Kadena AFB case number. ================================================================ SEARCH INDEX TERMS ================================================================ Miami Florida Dade County 1952 April civilian amateur astronomer full moon silhouette dark opaque circular objects formation west east heading ninety degrees moonlit night haze ring Van Derear artist observer son nine year old child witness 435th Troop Carrier Wing Sharpe WIN 2-52 AFOIN insufficient data for evaluation not identified four objects disc dark leading edge corona fuzzy one second duration no sound no light no reflection Status Report 7 Kadena AFB Okinawa Korea misfiled bundled C3 evaluation ground visual silhouette ================================================================ CASE ANALYSIS -- Claude Sonnet 4.6 ================================================================ CASE OVERVIEW On the night of 5 April 1952 at 2115 EST, an amateur astronomer and his nine-year-old son were lying in hammocks in their Miami yard, watching an almost-full moon through a hazy atmosphere. In the course of roughly one second, four dark circular objects passed through or near the moon's face. No photographs were taken. No other observers reported the same objects. The official conclusion is Insufficient Data for Evaluation. THE OFFICIAL CONCLUSION "Insufficient Data for Evaluation" is the recorded conclusion, with a secondary notation in the Other field that is handwritten and illegible in the surviving scan. The Wing Intelligence Officer who interviewed Mr. Van Derear found no reason to doubt his account and rated him as better qualified than the average observer. The Status Report entry records "No conclusions." The case was not resolved to any conventional explanation, but neither was it classified UNIDENTIFIED. Given the brevity of the observation and the lack of corroborating witnesses, the classification is honest. WHAT THE EVIDENCE SHOWS The primary observer, Mr. Van Derear, is described in the AF Form 112 as a competent artist who had been observing the sky at every available opportunity for three or four years in the hope of seeing flying saucers. He owned a small telescope but was not using it. The moon was almost full and surrounded by an atmospheric haze ring. There were no clouds. The observation itself lasted roughly one second for the object that transited the moon's face most directly. Four dark shapes in total passed at or near the moon, crossing from west to east in what appeared to be formation. The most carefully observed object blocked out approximately half the moon's apparent diameter -- an angular size of roughly 0.25 degrees. It was completely opaque, perfectly circular (per the father), and completely silent. The leading edge was sharply defined. A fuzzy corona surrounded approximately 300 degrees of the object's outline -- meaning only the leading edge was crisp, while the remaining three-quarters of the perimeter faded into an indistinct halo. The son saw one of the objects as an irregular shape rather than circular. The intelligence officer regarded the father's observation as more reliable on the grounds that he was a trained artist "accustomed to noticing shapes." After the sighting, Mr. Van Derear retrieved his telescope and searched the sky for some time without finding anything else of interest. WHAT GIVES ME PAUSE -- AND WHERE THE CASE SOFTENS Several details argue for a mundane explanation, and one argues against it. For the mundane side: April is peak northward migration season in Florida. Large wading birds -- herons, ibises, spoonbills -- migrate at night in loose flocks, sometimes in V-formations or staggered lines. Viewed against a bright moon at altitude, a large bird would appear as a dark silhouette. The son's observation of an "irregular" shape is consistent with a bird in flight. The one-second transit time is consistent with a fast-flying bird at low to moderate altitude passing through the narrow column of the moon's disc. The fuzzy corona on the trailing 300 degrees of outline could be the blurred impression of beating wings, tail feathers, and the general non-circularity of a bird's body at a distance. Against that: the father's perception of a "perfectly circular" shape. An amateur astronomer trained as a competent artist, who has spent years looking at the sky through a telescope, is someone with reason to be trusted on geometric shapes. He did not report an uncertain shape; he described a precisely circular opaque disc. The sketch he drew shows a clearly bounded circular object. That is not what a flying heron looks like at any distance. The asymmetric sharpness is also genuinely interesting -- a leading edge sharp, trailing three-quarters fuzzy. This is not what you would expect from a rigid circular disc (which should present a uniformly sharp edge), nor quite what you would expect from a bird in smooth level flight. It could describe something passing through the haze layer at speed, with turbulence or diffraction softening the trailing edge. There is also the psychological detail worth holding lightly in both directions: this was a man who had spent years wanting to see flying saucers. That primes identification in one direction. But he said he was disappointed, that they seemed "almost a natural manifestation, except for the perfectly circular shape and the fact that they appeared to be flying in formation." A true believer expecting spectacle would not have been disappointed. The understated, almost puzzled quality of his account suggests he was describing what he actually saw rather than what he hoped to see. BOTTOM LINE This case is thin by the standards of the Blue Book record. One observation pair, one second of observation for the clearest object, no photographs, no corroborating witnesses, and no trajectory or altitude data. The conclusion of Insufficient Data for Evaluation is defensible and probably correct. The most likely mundane explanation is migratory birds silhouetted against the moon, with the father's "circular" impression being a misread of a bird's body in brief transit. The son's "irregular" description is more consistent with birds than with discs. But the father was a trained observer of shapes who knew the difference between irregular and circular, and his disappointment at the mundaneness of the experience does not read as someone confabulating saucers out of herons. The case does not rise to UNIDENTIFIED under any reasonable standard. It also does not fully close. It sits where the official conclusion put it: not enough data to say. ================================================================ END OF DOCUMENT ================================================================ GlitchyMatrix.com/bluebook/ ----------------------------------------------------------------
