Ok, then no insults.  But the question stands:

Are the firefighters in the video lying?

Is the one firefighter's description of "boom, boom, boom - floor by 
floor, like detonators" just his imagination?

I would imagine that the sound of the upper floors collapsing onto the 
floors below may tend to make a booming sound, or in your world would all 
of that falling concrete and steel be whisper quiet?

In "my world" NYC professional firefighters would have some idea of what 
falling concrete and steel would sound like, and it would not prompt them to 
gesticulate and say that it was like a series of detonators going off.

We can leave it to other readers here to decide if your position makes more 
sense than that.
