Cargo Aircraft as Terror targets
Terrorists could still get a bomb aboard a commercial plane in cargo, which is virtually unscreened.
Kathleen Sweet, a lawyer, author and retired U.S. air force lieutenant-colonel, said air freight, and the workers who load it, are "a huge gap" in aviation security.
Very little has been done to secure cargo even though passenger-screening techniques have improved dramatically in recent years, said Sweet, an expert in aviation security.
