Security Expert: 11 Years After 9/11, Airports 'Remarkably Safer'

The two planes that pierced the North and South towers of the World Trade Center in New York City 11 years ago Tuesday departed from Boston's Logan International Airport — a fact that heightened scrutiny at Logan, and led to an overhaul of security procedures.

Peter DiDomenica, a state police veteran, was brought in as Logan's director of security policy after 9/11.

Since then, through his own private company, DiDomenica has trained airport and mass transit security screeners around the world.

Now a member of the Boston University Police Department, DiDomenica joined Morning Edition Tuesday to discuss airport security.
