A mixed 1954–55 file that includes a 6 July 1955 Newfoundland event involving KC-97 crew observations and ground-radar returns. The reviewing committee could not explain the simultaneous radar and visual reports, but provisionally accepted an electrical phenomenon for the radar and aircrew misinterpretation for the visual account. It classified the incident as UFOB while recommending immediate fighter scrambles for future comparable events. The record is notable for preserving both the unresolved correlation and its cautious, prosaic provisional explanation.
