This from Steve Redick:

I want to share something of historical significance. This is a tape recorded interview with Bill Bingham in 1976. “Coach” was a senior fire alarm operator and one of the many bosses I was fortunate to work for. He was a fire telephone operator in the office the day of the tragic Our Lady of Angels school fire. In this interview Bill recounts his memories of that terrible day. It provides a lot of insight into the CFD and its operations as well as the fire itself.
