It’s hard to believe that the September 11 terrorist attacks happened 20 years ago this month. Of the nearly 3,000 people killed at the World Trade Center, the Pentagon, and in rural Pennsylvania, more that 400 were emergency responders, including 343 firefighters.   On today’s podcast, we consider how that day forever changed the US fire service. First, we’ll look at the dedicated responder network FirstNet and how incident communications have been revolutionized since 9/11(1:02). Then, we’ll talk to two national leaders in the US fire service, who reflect on their own experiences in the aftermath of the attacks and tell us what they think are 9/11’s lasting legacies (23:44).
