That is odd how even details seem vivid in these odd but profound circumstances. I distinctly remember Carl Kasell announcing the news on my way to class. Was unimportant, because there weren't really any details. But the the instructor arrived 15 minute late for class, wheeling in an AV cart, and turned the news on just in time to watch one of the buildings collapse through a super grainy signal. Everyone was stoic, until this one lady who worked for American Airlines realized that it was AA planes involved and she had a meltdown; I guess they must have had a kind of family type environment at AA. I don't know, but we never saw her again the rest of the semester. The instructor, after several minutes more, got rid of the TV and we continued with the lesson, to everyone's astonishment. My afternoon class was then cancelled.
