FAA halts flights to Reagan, Dulles and BWI after key radar facility evacuated

A key air traffic control facility serving the Washington, D.C. region was suddenly evacuated Friday, forcing the Federal Aviation Administration to halt flights to several major airports, according to CNN aviation correspondent Pete Muntean.

Muntean said on-air Friday that early information suggests smoke may have triggered the evacuation, though officials have not confirmed the cause.

The disruption affects Reagan National, Dulles, Baltimore/Washington International, Charlottesville, and Richmond airports.
