More than 100 flights at Dallas-Fort Worth International Airport were delayed Thursday after non-essential employees were evacuated from a government air traffic control facility because of a sewage odor Thursday.
Lynn Lunsford, with the Federal Aviation Administration, told NBC 5 the Fort Worth Air Route Traffic Control Center continued to provide air traffic services at a slightly reduced rate as they rotated personnel in and out of the building.
Thursday afternoon officials said the odor was related to sewage and that plumbers were making repairs.
