'60 Minutes' Looks At Sept. 11

Have Americans recovered from last year's terrorist attacks? How has life changed? Is the nation prepared for another attack?

These are some of the questions 60 Minutes considers Sunday in a special two-hour edition devoted exclusively to the events of Sept. 11 and their impact around the globe.

Among the reports scheduled:

• Correspondent Ed Bradley returns to Summit, N.J., a commuter town that lost many of its residents in the attack on the World Trade Center. His report focuses on the healing process taking place in town, looking specifically at how the Rancke and Thompson families have fared in the year since they lost their husbands, fathers and providers, Todd and Ian.
• New York Fire Department Commissioner Thomas Von Essen, who was in charge the day 343 firefighters died at the World Trade Center, is interviewed by Correspondent Morely Safer. With a year's perspective, Von Essen looks back on the events of 9/11 and discusses what has been learned since then about his department's actions that day.
• The investment banking firm Sandler O'Neill lost a third of its employees and all its business records in the attack on the World trade Center. In a new report, Correspondent Steve Kroft finds that business is flourishing as the firm helps the families of its Sept. 11 victims and continues to hire new employees to replace those who were lost.
• Correspondent Mike Wallace speaks to Secretary of Health and Human Services Tommy Thompson on America's readiness for future attacks, especially from biological or chemical threats.
• In Saudi Arabia, Correspondent Lesley Stahl looks at one detail: terrorist leader Osama bin Laden and 15 of the Sept. 11 hijackers all hail from that country. Does Saudi Arabia, an American ally, harbor any animosity toward the U.S.?
