Six people were killed in Rio de Janeiro when two helicopters collided in mid-air, sending one plummeting into an electric vehicle dealership. The explosive impact and subsequent secondary explosions ignited a massive fire that engulfed approximately 20 cars before emergency crews could extinguish the flames. The second helicopter, carrying a lone pilot, crashed upside down nearby without catching fire, leaving no survivors from either aircraft. Authorities have launched a formal investigation, noting that with wreckage scattered hundreds of meters across the area, the effort to determine the exact cause of the crash is still in its preliminary stages.
