Puerto Maldonado UFO sighting — 1952

Peru, Puerto Maldonado: On July 19, the attention of Customs Inspector Sr. Domingo Troncoso, on the jungle frontier with Bolivia, was called to a very strange cigar-shaped flying object over the river area. The big dirigible-shaped craft was flying horizontally and fairly low in the sky, passing from right to left from the observer’s position. It was leaving a dense trail of thick smoke, vapor, or substance on its wake. This object was a real, structured, physical machine and may be seen from its reflection in the waters of the Madre de Dios river underneath it. The object was estimated to be over a hundred feet long.
