I don't think the guy with the gun made it on the plane. Think after he was stopped, they profiled the ones who were already on the plane. At least thats what i hope happened. Hard to tell from the article.
Yep - just found on CNN.com (OK, OK, sorry, but I wanted confirmation) - he was NOT, repeat, NOT on the plane, yet.
The other terrorist conspirators WERE (my labeling, but, it seems most likely).
