According to Los Angeles Airport Police, at approximately 10 a.m. EST., an unidentified passenger, wearing a striped red and navy blue sweater with black pants, rushed to the front of the plane, while the plane was pushing away from the gate, and asked the flight attendant, "what do I do now?"

Passengers told FOX 11 that the flight attendant insisted that the man sit down, but he ran from the Delta Air Lines flight attendant and went to the plane's emergency exit doors, turned the latch, opened the door and slid down the deployed emergency slide. 

The plane was forced to stop, and passengers told FOX 11 that the man jumped onto the back of a baggage cart, where luggage workers held him down until LAX Police got there.

"Delta was great. The flight attendants were amazing," said Gillian Sheldon, who was on the plane. She told FOX 11 that the whole thing happened so fast that no one had any time to react.

"Just glad it didn’t happen when we were midair, or it would have been a whole different outcome."
