RB-47 Multi-Channel Radar-Visual Encounter (1957)

July 17, 1957Mississippi-Louisiana-Texas-Oklahoma flight corridor, South-Central United States, United States

Hynek summarizes the RB-47 case as a roughly 1.5-hour, more-than-700-mile encounter involving six Air Force officers. An intensely luminous object was reported visually, followed by ground radar, and detected by onboard ECM equipment, with several simultaneous appearances and disappearances across the independent channels.
