================================================================ PROJECT 10073 RECORD CARD -- TRANSCRIPTION File: Pg-1_1963-08-9733466-Vandalia-Ohio.pdf Transcribed from document image by Claude Sonnet 4.6 ================================================================ FIELD 1 -- DATE: 30 August 1963 FIELD 2 -- LOCATION: Vandalia, Ohio FIELD 3 -- DATE-TIME GROUP: Local 1915 / GMT 31/0015Z FIELD 4 -- TYPE OF OBSERVATION: Ground-Visual [X] Ground-Radar [ ] Air-Visual [ ] Air-Intercept Radar [ ] FIELD 5 -- PHOTOS: No [X] FIELD 6 -- SOURCE: Civilian FIELD 7 -- LENGTH OF OBS: 30 seconds FIELD 8 -- NUMBER OF OBJECTS: Two FIELD 9 -- COURSE: [not recorded] FIELD 10 -- BRIEF SUMMARY: Two bright red lights moving very fast. Disappeared behind clouds. No positional data obtained. Appeared like childs rulers about 3 inches apart. Observed through windshield of moving car. FIELD 11 -- COMMENTS: No mention of disappearance other than disappearing behind clouds. This tends to rule out reflections and indicates that the objects were in the air. Nothing conflicting with a/c analysis. Sighting of airborne lights at night for brief duration. Case considered as an a/c sighting.

Red lights are consistent with aircraft navigation and anti- collision lighting. Disappearance behind clouds is expected behavior for any airborne object. The windshield-reflection hypothesis was considered and ruled out. On a pure checklist basis this case closes cleanly. WHAT GIVES ME PAUSE The "childs rulers" description is the most unusual element here and it is the one the official record passes over without comment. The observer did not say "two lights side by side." They reached for a specific geometric metaphor -- parallel rulers, approximately 3 inches apart in apparent angular size, held presumably at arm's length through a windshield. That is a very precise spatial comparison for a 30-second observation from a moving vehicle at night. It suggests the two lights maintained a rigid, consistent separation throughout the sighting -- they moved together as a unit rather than as independent points. For conventional aircraft this matters. Navigation lights on a fixed-wing aircraft appear to change their angular relationship constantly as the aircraft banks, turns, or passes overhead. A rigid, ruler-like parallel pairing held steady for 30 seconds is more consistent with an object moving directly away from or toward the observer on a constant heading -- or with a single object carrying two lights at fixed separation. THE SPEED QUESTION "Moving very fast" combined with a 30-second observation and no recorded compass bearing is an odd combination. If the objects were crossing the observer's field of view at high angular velocity, 30 seconds would place them across a wide arc of sky -- yet no course was recorded and the only termination event noted is cloud cover. If they were moving fast in terms of true airspeed but at high altitude (reducing apparent angular velocity), the "very fast" description would be harder to account for from a ground observer's perspective. The investigator did not attempt to reconcile these details. THE OBSERVATION CONDITIONS A civilian observer, moving vehicle, 7:15 PM local in August (civil twilight or just past it in Ohio), looking through a windshield. These are genuinely degraded conditions that favor misidentification. Two aircraft in formation or on converging approaches to Dayton's airports (Vandalia sits immediately north of what is now Dayton International) could reasonably produce this observation. The area's proximity to Wright-Patterson AFB is also worth noting -- military traffic at that location was common and sometimes fast. BOTTOM LINE "Probably Aircraft" is the most parsimonious explanation and I would not argue it is wrong. But the geometric precision of the observer's ruler description deserved more attention than it received. A formation of two aircraft on a constant heading away from the observer, at relatively low altitude given the proximity to Dayton approach paths, accounts for most of what is reported. What it does not fully account for is why a civilian familiar enough with aircraft to not report the observation as extraordinary nonetheless described the lights in terms specific enough to note their parallel geometry and approximate angular spacing. Most aircraft sightings do not produce that level of spatial detail. Not unidentified. But not fully explained either. ================================================================ END OF DOCUMENT ================================================================
