A passenger on Southwest Airlines Flight 1702 to Las Vegas about to depart from Los Angeles International Airport was arrested after he punched a flight attendant and opened the plane's rear door. The attendant was treated for minor injuries. No one else was hurt. Authorities said the Las Vegas-bound plane was pulling away from the gate when a 6 foot 2, 210-pound passenger stood up. "He approached the rear of the aircraft with a shoe in his hand and as a flight attendant tried to prevent him from opening the rear door, he hit her in the head with his fist," FBI spokesman Matthew McLaughlin said. The man, who authorities said was believed to have been drinking, got the door open but surrendered when two male passengers moved to subdue him. He was jailed without bail pending an appearance in federal court Tuesday, the FBI spokesman said. The flight departed about two hours after the incident.
