Reply #39: And how did the sprinklers survive the impact?

[hack89]

Don't you think perhaps the 767 that plowed through multiple floors would destroy most of the sprinkler heads and piping?

This minor detail of a 100 ton plane slamming into the building at high speed always seems to be forgotten when ever comparisons between Madrid and the WTC are made.

As for the fuel loading of the buildings, go here:

you'll see that there was plenty of material to fuel large fires.
