St. Louis-bound AA Flight Returns to NYC

St. Louis, MO – Shortly after the plan took off, a passenger complained of eye irritation. But three people who say they were passengers on the flight say that after security guards escorted a man off the plane, smoke began billowing from behind where the man had been sitting. They say security guards then removed a man with a backpack who was sitting at the back of the plane. The three say the plane finally took off after the remaining passengers were taken off the plane and checked in again. Officials say they can't confirm that.
