Harrington was working on the installation of new furniture in Wedge One, when he was called out to the parking lot to talk about security with his customer moments before the crash.
"About two minutes later one of my guys pointed to an American Airlines airplane 20 feet high over Washington Blvd.," Harrington said. "It seemed like it made impact just before the wedge. It was like a Hollywood movie or something."
Doesn't contradict NoC.
