Hazmat crews boarded to scope things out, but were unable to trace the smell to any substance or chemical leak.
"After specific monitoring and hazmat crews entering into the fuselage no substances were found,” Myrtle Beach Fire Department Lt. Christian Sliker said, per a report from NBC New York. “The plane is all clear.”
Eventually, passengers were able to board a supplemental aircraft that was sent to continue them on their journey, and they made it to Ft. Lauderdale by around 5am Friday morning, roughly five hours after they were scheduled to land.
As of now, it's still unclear exactly where the smell was coming from, but let this serve as a friendly reminder that it's kind of gross to go shoeless on a plane, and that if you do decide to let your barking dogs breathe, for the love of god make sure they don't stink.
