Passenger opens emergency door mid-flight

This is scary! A passenger on an Asiana Airlines flight in South Korea opened the emergency door mid-flight. I didn't think that was actually possible, but apparently it is. 12 people were hospitalized. But this video does show that the movies have it wrong because no one was sucked out of the plane. It was just REAL windy, like sitting in the back seat of a convertible racer car.
