Nov. 8 (UPI) -- Federal officials on Saturday canceled more than 800 flights at airports across the United States as the federal government shutdown entered its record-long 39th day on Saturday.

Transportation Secretary Sean Duffy and FAA Administrator Bryan Bedford jointly announced a temporary 10% reduction in flights at 40 high-traffic airports.

They said the reduction in flights is necessary to ensure safety and ease the strain on air traffic controllers, who are working without pay.

"My department has many responsibilities, but our number one job is safety," Duffy said.
