Looks like a little bit of a hike for the 2nd and deeper due companies. Google Maps says over 10 minutes. That's gotta feel like an eternity when the first due is stretching to the top floor and looking for back up.
Kudos to UnitWithTheUrgent and others for a super rundown, which included the time of the various events. Helps with locating specific events in the archives, especially for a job this long.
Do the math and you see that between 550 and 600 firefighters responded to the scene at one point today. The majority of departments in this country don’t have that many total members. And only like 25 - 30 departments in this country have that many on duty at a time.
