We had a fire drill this morning at work. The fire official who addressed us capped off his little speech with the caveat that all he had just told us was contingency for a fire orginating within the building. He then went on to say that it does not cover a circumstance where, say, a plane flies into the building. I think he illustrated this scenario by describing how you might hear a loud "boom" and feel the building shake. I guess there is no contingency for the plane scenario. Great, thanks, I feel better about working in the heart of Manahattan now.
