Passengers on an United Airlines flight at Reagan National Airport had to evacuate the plane after smoke was reported in the cabin as the plane prepared for takeoff, the Metropolitan Washington Airport Authority said.
The Houston-bound flight was taxing for takeoff when emergency crews were called for a report of smoke in the cabin on Sunday at about 1 p.m.
Officials said in a statement that passengers and crew members were evacuated without incident using slides and were returned to the gate. Airport authorities say normal airport operations have resumed.
United Airlines tells The Washington Post that the issue affected a Mesa Airlines flight that operates under the United Express brand. The cause of the smoke was not immediately known.
