In July 2011, a tragic hot air balloon accident in Brazil claimed the lives of at least 16 people near the city of Carambeí, Paraná state. The balloon, carrying passengers on a recreational flight, reportedly caught fire and crashed into a field. Investigations pointed towards a possible propane gas leak as the cause of the blaze. The disaster highlighted the potential risks associated with hot air ballooning and prompted calls for stricter safety regulations within the industry in Brazil.
