Thousands Evacuated at S.F. Airport By KIM CURTIS, Associated Press Writer SAN FRANCISCO (AP) - Thousands of people were evacuated from San Francisco International Airport early Wednesday after security guards detected explosives residue on the shoes of a man who disappeared into the crowd, an airport spokesman said. ``When they went to stop him, he didn't stop,'' spokesman Mike McCarron said. A search for the man was underway. The explosive material could be anything from fireworks residue to nitroglycerin tablets, McCarron said. It was detected after a gauze-like material was wiped across the man's shoes, then put through a machine.
