🇺🇸 USAF — Project Blue Book
In November 1961, a witness in Diboll, Texas reported observing an object that initially appeared to be the Echo I satellite. The object was seen for about 5-8 minutes, moving eastward, and was described as bright, star-like, but with motion. The curious part was that although its appearance matched the satellite, its movement direction was unusual. The report concluded it was a satellite, as it matched the known orbit of Echo I at that time. The witness, a professional engineer, confirmed the object showed no aircraft lights or other signs of planes. The night was clear, with many visible stars, aiding the observation.
The report includes detailed location, time, and weather conditions, and was reviewed by the U.S. Air Force as part of Project 10073. Although initially thought it could be a balloon or aircraft, the final conclusion pointed to a satellite. The witness even sketched the object's movement and described its sudden disappearance, which caused some confusion. This case is an example of how observers reported phenomena that, after analysis, were identified as known objects, but generated doubts and required investigation at the time of observation.
