Most companies with hundreds of billions in market cap would not send many important people on a single plane together. Freescale, not quite that large, arguably made a significant business mistake here, but the market impact so far seems limited.
When was the last time you heard of 20 employees of a company being murdered?
To do so by killing 220+ other people makes such a theory even more absurd.
I knew I should have specified something along the lines of "and as part of a criminal fraud or theft or deliberate talent destroying act, or..."
As you say, the sole purpose of 9/11 wasn't to target those specific companies.
You'll need to explain that one for me.
Right now, it sounds awfully like you're trying to pin a story on an accepted tragedy. (for me at least...)
