Then you have to consider the Other ones on that day's list:
Twin Towers - BIGGEST thing around NYC and perfectly exemplifying the Wealth aspect er 'Symbolised' - no?
Pentagon.
White House? OR Congress?
That third one failed, thanks to cel- *communication* of the actual intent! to simply ordinary courageous people - who behave in such ways when they know enough to see Why. Did anyone ever suggest that cowardice aided the successful ones? I sure didn't - they Did Not Know, and rationally expected merely to be hijacked. As all surely realize.
Surely more people damage could easily have been caused than by picking the Symbolic and massively-walled Pentagon. (There were no Armies compressed inside there).
Surely too, the White House (never did hear how 'certain' was that guess) would contain a paltry number of bodies. Congress, for having even more bodies than WH: cannot be other than Symbolic. IMhO.
So.. was it Just to kill lots? then why not not [fill in the blanks for people-dense locales in every big city] or wait for a full stadium a la Black Sunday, was it?
I Don't Know {how the targets were weighted for Effect} ...
Do you think You Do?
