This from Drew Smith:

In July of 2018 the PHFD faced its largest ever fire, and one of the largest fires in the northern suburbs, at the River Trails condos. Reaching 5 alarms, two special alarms, and an interdivisional task force, more than 200 firefithers and 50 companies fought the fire.

Fire photographer Steve Redick, a retired Chicago FD dispatcher, created this compilation of radio traffic and his photos and videos that chronicles the start to finish. The 45 minutes is worth a look.
