Details Emerge About 9/11 Terrorist At Logan Airport

Court documents are revealing more details about hijacker Mohammed Atta's activities at Logan International Airport six months before the Sept. 11 terrorist attacks.

An American Airlines technician first told WBUR in 2002 that he had intercepted Atta at Logan months before the terrorists attacks.

Now, in court documents, American Airlines technician Steve Wallace reveals that after watching Atta and another man videotaping an American Airlines checkpoint in Terminal B, Wallace told a state trooper, "These two clowns are up to something."

Wallace and the trooper watched Atta's bag on the X-ray machine, but then Wallace had to take care of another problem.

He left the trooper at the checkpoint, but the trooper never asked for identification from Atta nor did he interrogate him.

The testimony is part of a lawsuit being filed by the family of Mark Bavis, who was killed on 9/11.
