FORT LAUDERDALE, Fla. -- In the airport of the future, security may begin even before you enter the terminal.
Among the possible changes: As soon as you buy a ticket, authorities would probe whether you're on an FBI watch list. Pull into the airport garage and imaging machines, similar to those at checkpoints, would scan your car. And motion sensors would sound alarms if an airport perimeter is breached.
As the nation reflects on the 10 years since the Sept. 11, 2001, terrorist attacks, the Sun Sentinel asked five prominent security experts how they would redesign airport security systems.
