AI-Generated Summary
A Boeing engineer reported a bright, steady, fast-moving object over Seattle on June 9, 1963. The Air Force concluded it was likely a Navy aircraft conducting high-altitude strobe light experiments.
On June 9, 1963, a research engineer from the Boeing Aircraft Company, along with four other individuals, observed an unidentified object in the sky over Seattle, Washington. The sighting lasted approximately 20 minutes, from 100045Z to 100105Z. The witness, who possessed experience in plotting satellites such as Sputnik, described the object as a brilliant white light with no color or blinking features, moving in a straight path from SSW to NNE at an estimated altitude of 300 miles and a speed of 15,000 mph. The object was noted to be brighter than Sputnik but moving slower. The witness observed the object through 8x binoculars. Dr. Hynek was involved in the follow-up of the report. Official investigation by the Air Force considered the possibility that the object was a Navy aircraft from Whidbey Island that was experimenting with a high-altitude strobe light at the time of the sighting. The report notes that the satellite ECHO I was not visible in the area during the time of the observation.
Since the Navy a/c was in the area at the time and experimenting with a high alt strobe it is possible that this was the a/c observed.
