On the morning of Friday, September 27, residents from Volta Redonda, Pinheiral, and Piraí in southern Rio de Janeiro reported hearing two loud explosions around 10:48 AM. The noise was intense enough to rattle windows and doors and alarm the population. As of now, there has been no official confirmation regarding the cause of these loud sounds, leading to numerous speculations and fears among the locals.

Witnesses described the phenomenon occurring in a short time frame, with many expressing their fright over the unexpected disturbance. For instance, a local law graduate, Jordana Prata, provided her account of the terrifying experience, stating that the noise was not only heard in nearby neighborhoods but also as far as more distant areas. This level of disturbance typically signifies something unusual, raising questions among the community about potential causes including a sonic boom, an explosion, or even an aircraft incident.

At this moment, local authorities and official bodies have not issued definitive statements clarifying the cause of the explosions, which complicates the situation, as residents seek answers. The discussions surrounding the incidents also include what's known as a 'Sonic Boom,' a phenomenon that occurs when an object travels faster than the speed of sound, but no concrete evidence has yet emerged to confirm this or any other theory. The lack of official information continues to fuel anxiety among residents of the affected areas, highlighting a need for clearer communication from local authorities about the situation.
