RB-47H electronic-intelligence aircraft incident

Record summary

An RB-47H electronic-intelligence aircraft crew reportedly encountered an unusual target during a training or operational flight in July 1957. Accounts describe emissions detected by the aircraft’s electronic-support equipment, later radar tracking, and a visual observation by crew members, with the reported track extending across several states. The case became prominent in UFO literature because of the apparent correlation among airborne sensors, ground radar, and crew testimony. The exact route, chronology, and official interpretation require checking against Project Blue Book and Air Force records.
