Excerpts from cbsnews.com:

Hundreds of firefighters from across the Chicago area gathered in Glenview for high-rise fire training. The victims are fake, but the first is very real. The training comes one week after a Chicago firefighter collapsed and died in the stairwell of a Gold Coast high-rise. The importance of practice is not lost on anyone.

All of the radio traffic from the training has been recorded so the instructors can go over it with each department and figure out what went right and what could be improved. For many of the firefighters, this is the only chance they’ll have to train in these conditions unless they face the real thing.
