🇺🇸 USAF — Project Blue Book
A round object was spotted over a runway at Eglin AFB, Florida, in 1957. Witnesses described it as a sphere with a white light, resembling a balloon. The object was observed for five minutes and made circular movements. Although no photos were taken, several officers confirmed the description typical of a balloon. It was noted that night-launched balloons often carry lights, supporting this explanation. Weather conditions and high winds also suggest it could have been a balloon.
