In 1954, Hary Rogen and Derick Noidon’s hot air balloon while participating in a hot air balloon show, suddenly mysteriously vanished into the Demon Triangle. After much search effort, there was no trace of the ball and its two owners. In 1990, the missing hot air balloon suddenly appeared in the same spot where it had been missing for 36 years, in front of thousands of astonished eyes of the public participating in the hot air balloon contest in Cuba.
