🇺🇸 USAF — Project Blue Book
In August 1954, a witness in Iceland reported seeing a dark cylindrical object about 25 cm in diameter and 60 cm long. The object made a whizzing sound and traveled at high speed before falling into a sandbar in the Lagerfljot River. Authorities attempted to recover it, but the river had changed its course multiple times, complicating the search.
The investigation concluded that other explanations like a meteorite or aircraft could not be ruled out, but the object was never found. The nature of the phenomenon remains unresolved, adding another mystery to the UFO files of that era.
