Flight 93 heroes remembered 25 years after 9/11

It's been 25 years since the 9/11 attacks, when Al Quaeda terrorists hijacked four commercial planes, crashing two into the twin towers in New York City and one into the pentagon. There was also that 4th flight, where passengers fought back and stopped the hijackers from reaching their intended target in Washington D.C. The plane eventually, crashed into a field in Shanksville, Pennsylvania. Pete Cuddihy joins us from Shanksville at the Flight 93 memorial.
