And their actions that day, banding together to fight the terrorists, would inspire the nation.

Our first full report on this incredible story aired in early October 2001. With the country still reeling from the 9/11 attacks, family members introduced us to the heroes of Flight 93.

They told us how they remember that awful day and how they've coped with their loss. They also brought us up to date on their lives today, 20 years later. It's a story of remarkable resilience.
