(Getty Images) (Newser) – A passenger who tried to open an emergency door on a Delta flight from Orlando to Boston was quickly subdued by an off-duty cop. The incident, the fourth in-flight security scare on a domestic flight in the space of 3 days, appears to be have been alcohol-related rather than terror-related: Multiple passengers describe the man as a foul-mouthed drunk who had been drinking in the airport bar in Orlando before the flight. "I actually saw him in Orlando and he asked me to go to the bar with him,’’ one passenger tells the Boston Globe. ‘"He was very intoxicated." The police officer who subdued the passenger sat with him until the flight reached Boston, where the passenger was arrested on suspicion of interfering with a flight crew.
