Ubatuba (Brazil) — September 10, 1957

Approximate date. Anonymous witnesses saw a disk dive down and explode, shower- ing the area with flaming fragments. Some samples were gathered, sent to a Brazilian newsman, analyzed by friends of Dr. Fontes, of Rio, and were found to consist of surprisingly pure magnesium. (Lor.190; 110)
