🇺🇸 USAF — Project Blue Book
In 1949, in La Porte, Pennsylvania, a mysterious object was reported hovering at low altitude with explosions and lights. The object was recovered and turned out to be a donut-shaped structure made of thin iron or steel, painted matte black and weighing 20 pounds. Although initially considered a balloon or astronomical phenomenon, investigators concluded it was a hoax. The case was meticulously documented and stored in military archives, but no evidence of extraterrestrial activity was found.
