🇺🇸 USAF — Project Blue Book
In March 1956, a witness in California observed a white, luminous object oscillating in the sky. The object, described as the size of a match head held at arm's length, was seen for a few minutes before fading away. The person spotted it while driving on the highway, adding a mundane context to this mysterious encounter.
The official investigation concluded that the object was a balloon, as it matched recorded launches in the area. Two MDH-type balloons had been launched hours before, supporting this explanation. Despite that, the object's unusual appearance and oscillating motion keep a sense of mystery, typical of many UFO cases.
