A firefighter / chief who thought that uncontrolled fires generally burn themselves out, causing local collapses (floors, sections) at worst, before 2008 (the publication of the NIST report), will feel "greater urgency" about getting fires under control after 2008, since there seems to be more at stake, i.e., the total collapse of whole skyscrapers.In hindsight, what do you think the firefighters could have done with regards to WTC7 to have shown "greater urgency"?
If firefighters had known then (on 9/11) what they know now, they might have spent those three hours (from 2:30 onwards) working very deliberately (and with great urgency) to get water to the building (from the Hudson) in hopes of avoiding further thermal expansion. Remember that in the days and weeks after 9/11 a lot of water was eventually poured on the site. So the water problem did get fixed. I'm saying they would have worked to the last second -- i.e., up to the moment of collapse -- to expedite this solution.
Obviously, they would also be very wary of actually entering the building. But some effort to avoid the complete collapse of the building (knowing that the relevant effort to be made is to reduce the temperature of the steel, i.e., get water on the fires) would surely have made sense, if they had known the mechanism that eventually brought the building down.
