A mysterious sonic boom rattled homes across the South Carolina Midlands on Thursday night, May 29, 2026 [1].
The event caused widespread alarm among residents and prompted immediate investigations by federal agencies to determine if the rumble was a natural disaster or man-made.
Hundreds of residents [2] reported hearing a loud boom and feeling a physical shaking in their homes. The phenomenon was felt across a wide area, including Columbia and surrounding counties [3]. Some reports indicate the boom was felt up to 100 miles away [4].
The U.S. Geological Survey (USGS) investigated the reports and ruled out an earthquake as the cause [5]. Similarly, NASA officials said the sound did not originate from a rocket launch or a meteor entering the atmosphere [6].
While the exact source remains unknown, some experts suggest the event was likely caused by an aircraft breaking the sound barrier [7]. The rumble was significant enough to shake roofs and windows throughout the region, creating a momentary panic for those unaware of the cause.
Authorities have not yet identified a specific flight or military exercise that corresponds with the timing of the boom. Local residents said the experience was a sudden, jarring shock that echoed through the Midlands [3].
“Hundreds of residents reported hearing a loud boom and feeling a physical shaking in their homes.”
The exclusion of seismic and celestial causes by the USGS and NASA narrows the origin of the event to atmospheric or man-made sources. Because the boom was felt over a 100-mile radius, it suggests a high-energy event, typical of supersonic aircraft, though the lack of an official military or aviation announcement leaves a gap in the public record regarding regional airspace activity.
