here is the deal, someone, in a car driving in their car near the airport saw the smoke, they knew someone who knew a pilot. The called them, they confirmed that smoke was bad coming from an engine(that person once knew an airbus rep from the factory). So anyways, that pilot, once shared a crash pad with a NWA pilot, so they called him, that pilot contacted the company and they sent a message that they should abort the takeoff. so, thats how it happened.......in case you are not figuring it out, i am kidding........
