March 19 (Reuters) - The U.S. Federal Aviation Administration (FAA) said Thursday it had closed the air traffic control tower at Las Vegas International Airport after a controller was presumed to have contracted COVID-19.
A flight tracking website, flightradar24.com, said nearly 500 flights had been canceled at Las Vegas airport Thursday, which is receiving flights at a reduced rate.
Earlier this week, another control tower at Chicago Midway International Airport was closed after three technicians tested positive, resulting in the canceling of more than 50 Southwest Airlines flights Wednesday. The Las Vegas tower is being cleaned and the FAA is determining how many controllers will need to self-isolate. (Reporting by David Shepardson, Editing by Franklin Paul)
