Around 7:30 a.m. Wednesday, numerous people across Jefferson Davis, Lawrence, Lincoln, Franklin and Amite counties reported hearing a loud boom.

An hour later, no related emergency reports had been made in Lincoln County.

The chatter on social media was divided as to what it might have been, from an earthquake’s aftershocks to natural gas fracking. But one theory found its basis in the early morning sky.

Smithdale resident Kelsey Kyzar submitted a photo to Jackson weather station WLBT that shows a contrail from the SpaceX Crew-4 launch this morning — along with the alignment of the moon, Jupiter and Venus. Photos of the contrail were also submitted from Hattiesburg and Mobile. Could the sound have been caused by the craft passing over the area, or the booster re-entering the atmosphere?

At 4:52 a.m. CST Wednesday, the science expedition mission Crew-4 was launched from NASA’s Kennedy Space Center in Florida to the International Space Station. The vessel named Dragon will autonomously dock with ISS at approximately 9:15 p.m. CST, according to the SpaceX website. Webcast coverage of the event will resume at approximately 7:15 p.m. CST.

Updates will be posted when the source of the noise is identified.
