Reply #111: Your post (and included image) is what I call...

[AZCat]

an "ignoratio elenchi".

The difference (because you seem unable to determine it) between your photo and the incident under discussion (collapse of the buildings on 9/11/01) is that your example is a seismic example and therefore invalid for a discussion of collapses from other means (something that has been pointed out repeatedly by CTers). In case you didn't know, buildings respond quite differently to seismic activity than than forces applied otherwise - say, energy transferrence from falling floors.
