Workers at Savannah River Site returned to their jobs - also under heightened security. The site was back in operation and tritium production resumed.

Stranded air travelers rented cars or checked into local hotels. The passengers were aboard four flights that were forced to land at Augusta Regional Tuesday morning after the Federal Aviation Administration grounded all aircraft.

Augusta Regional made plans to change security procedures when flights resumed. The changes included: allowing only ticketed passengers at the airport gates; closing off access to the property except for the main entrance on Tobacco Road; stopping all cargo shipments; and requiring all passengers to show photo identification. All vehicles and luggage also would be subject to search.

Augustans continued to pack local blood centers and donate money to relief funds.

American flags flew off shelves, and red, white and blue ribbons began to show up on trees, homes, lapels and blouses.

The attack also brought out the worst in some. A maintenance worker was out early Wednesday morning trying to clean anti-Muslim graffiti off a sign at the Islamic Center of Augusta. A profane message to Osama bin Laden, along with the words ''coward'' and ''U.S.A.'' were spray painted late Tuesday. Shariq Hashmi, a Pakistani-born Muslim, said he was not surprised by the attack at the center or angered by it. He had expected it.
