here is a fairly complete article on the engineering of the building..
http://www.newyorker.com/fact/content/?011119fa_FACT

and no, i happen to work in a building that was build to "california earthquake standards" it is reenforced, very strong... (but it did quiver when the planes hit) the explodsion was so big, our building felt it, and its about .5 to .7 miles away (almost a k)but there wasn't much between us an the twin towers.

since last year, all of the windows in the building have been coated with protective sheets that help keep the glass for shattering, and when it does break it helps it to break into crumbs (roundish fractures) not shards..

it is a handsome building. (ask Jazzo! or Rubrick!)
