A Cessna airplane that breached restricted airspace and prompted evacuation of the White House and Capitol on Wednesday was escorted to Frederick, Maryland and the pilot is in police custody, a U.S. Homeland Security official said. The official said the light aircraft was escorted by fighter jets and helicopters and ordered to land in Frederick, which is just outside the restricted airspace around Washington, according to Reuters. The official said state police had the pilot in custody. He was not sure if there were any other people on board the airplane or where it was traveling from.
