Yes it happined at the gate. it was in the old termnal 4. the way it was set up was soon as u got through security there were gates right there. Some one ran through security and onto the first plane which was National. He then told people he had a gun and had the flight attendant shut the door. He ran and locked himself in the flight deck.
After he locked himself in the f/d the paxs wanted to get off the plane but the idiot f/a told them to sit down and remain calm, they pushed her out of the way and ran off the plane. the man surrendered that night it never left the gate
