Wichita's Eisenhower National Airport experienced passenger growth and American Airlines added a direct flight to DC a year before the deadly crash.

That’s because American Airlines has retired that number after the deadly plane crash in Washington, D.C., said Jesse Romo, Wichita’s director of airports. But on Friday, Wednesday’s flight information was still on the departure screens at Dwight D. Eisenhower National Airport.

Officials from Wichita, Kansas provide updates on the deadly plane crash at DCA. In order to enable safe flight, airspace is split into categories ranging from very tightly controlled areas around airports to other zones – mostly rural – where rules are much more relaxed.
