Lyric discussion by BarbedWireSocko 

I'm pretty sure the whole first verse is from the point of view of a firefighter going into the towers. I like your interpretation, but this seems to make more sense. The "On my back's a sixty pound stone On the shoulder half mile outta line" part is talking about his oxygen tank and his hose.

I dunno....with something so very serious....the job they had to do and what happened...such an upbeat sounding song...too much hope in the end...speaks of resolution, facing forward, helping each other, not the first responders going to their possible deaths
