We are marking the 20th anniversary of the 9/11 attacks in New York City, Virginia and Pennsylvania.
It was a day that changed so much about life in America, including how first responders respond to emergencies.
Joining "All Things Considered" for a discussion about this is Brian Foley, spokesperson for the Department of Emergency Services and Management.
He talks about what first responders learned from that day and how the coronavirus pandemic has likely made all of us more ready to respond to disaster.
