A passenger aboard a British Airways flight from London to Boston was taken into custody after trying to open the emergency exit door mid-flight.

Investigators initially thought the passenger—a woman around 30 years old—had tried to gain access to the cockpit. But after interviewing the crew and witnesses, the police determined the cockpit was secure and she was actually attempting to open the exit door. She was then restrained.

The Massachusetts State Police said over Twitter that the woman has no terrorism ties but was simply just intoxicated. She'll most likely face charges for interfering with flight crew.

This isn’t the first time something like this has happened. In September, a man mistook the plane’s exit for a bathroom door, and was later fined for his mistake. Just add, “read the door before you open it,” to your handbook for how not to be a jerk on an airplane.
